Backflow
Prevention Assemblies
Protect Against Contamination
by
Terry Nelson |

If
you are involved in the design, installation or
maintenance of irrigation systems, you need to become
familiar with backflow preventers and the role they play
in keeping our drinking water safe. They are more than
just fittings on a system of piping to deliver water.
Backflow preventers are installed in the irrigation
system to protect our drinking water, save lives and
prevent illness. If you understand what they do and why
they are needed, you will be able to ensure that the
projects you are involved with comply with local codes.
A good understanding of backflow preventers will also
help to reduce the risk of litigation against you from
creating a cross connection and putting public health at
risk.
You may think that our water supply is not threatened
by water used in irrigation systems. But, as reported in
the October 31, 1997, issue of the Los Angeles Times,
backflow incidents involving irrigation systems do
happen. This article reported, "Drinking water in
the system serving two schools and as many as 1,600
homes in Calabasas hillside neighborhoods was
contaminated with treated sewage water intended for
irrigation after a plumber working on a landscaping job
mistakenly crossed two pipes." Several people
became ill due to this cross connection and residents
were warned not to drink from their faucets or from
local water vending machines until the fresh water lines
were flushed and tested. The plumber involved was
exposed to potential litigation including the cost of
the clean-up.
This article will provide you with an introduction to
cross connection and backflow prevention to help keep
you within the law and outside the courtroom.
The Safe Drinking Water Act (SWDA) of 1974
established a national program that would ensure the
quality of America's drinking water. It included a
Federal mandate that the local water district provide
safe drinking water and authorized the Environmental
Protection Agency (EPA) to set standards for
contaminants in public water systems.
State and local codes have now been developed to
identify the requirements for ensuring that the water
distribution system provides safe water. Local codes
vary, but most cities have established guidelines on the
type of backflow preventers to install to help protect
the potable water supply. You should become familiar
with your local codes as they relate to irrigation
systems.
First, let's review some basic terms. Backflow
preventers are specially-designed valves used to protect
our potable (drinking) water supply from pollutants or
contaminants due to backflow from cross connections.
Backflow can be defined as the unwanted reverse flow
of any liquid, solid or gas in a piping system. In an
irrigation application, this means that water within the
irrigation system may find its way back into the potable
water system during a backflow incident.
Cross connections are the link or channel connecting
a source of pollution with a potable water supply.
Therefore, the irrigation piping system may create a
cross connection between the potential contaminants and
the potable water supply.
Pollutant is a substance that would affect the color
or odor of the water, but not pose a health hazard.
Applications where pollutants could enter the potable
water supply are considered non-health hazard
applications.
Contaminant is a substance that would cause illness
or death if ingested, and therefore, is considered a
health hazard. For example, water in the irrigation
system could come in contact with fertilizers used on
the lawn, waste from animals, pesticides used in the
surrounding landscape, or muddy water. Contaminated
water, which collects around a submerged sprinkler head
or chemicals in a chemigation system, could be drawn
into the irrigation system. Therefore, most codes
consider irrigation systems health hazard applications.
The appropriate type of backflow preventer should be
installed to ensure these potential contaminants do not
find their way back into the potable water supply.
There are two basic forms of backflow: backsiphonage
and backpressure. In backsiphonage, the water from the
irrigation system is siphoned or "sucked" into
the potable water supply. This can be caused by negative
pressure or loss of pressure. An example of this might
be a hand-held pesticide sprayer connected to a garden
hose. If negative pressure occurs while the sprayer is
connected to the garden hose, such as a break in the
main line water supply, the contents of the pesticide
sprayer could be siphoned out of the container. The
hazardous chemicals could then be carried down the line
into the potable water supply and cause serious illness
or death. If the garden hose had a backflow preventer
(hose bib type of vacuum breaker in this application)
installed at the point of use, the contaminant would be
prevented from entering the main water supply.
Backpressure is another common way contaminants enter
the potable water supply. This occurs when the pressure
in the system is greater than the supply pressure. In an
irrigation system this can occur when an auxiliary pump,
which is intended to boost pressure in the irrigation
system, has greater pressure than the city water supply.
Then the booster pump can "push" the
potentially contaminated water back into the potable
water supply. However, if the proper backflow preventer
is installed at the point where the irrigation system
and the city water supply meet, our drinking water will
be protected.
There are several different types of backflow
preventers available on the market today. Some of the
new designs have superior flow characteristics, shorter
lay lengths, come in multiple body styles and are easier
to service. Based on the application, system layout and
type of hazard, local codes may vary on which type of
backflow preventer should be installed for a particular
application. Consult your local codes or authority
having jurisdiction to determine which devices are
approved in your area for specific applications.

on the market today
Several organizations and agencies have established
guidelines for the design, manufacture, and performance
of backflow preventers. Some organizations and agencies
involved with the approval and/or certification of
devices include the Foundation for Cross Connection
Control and Hydraulic Research at the University of
Southern California, the American Society of Sanitary
Engineers, the American Water Works Association and the
Canadian Standards Association.
The following is an overview of the types of backflow
preventers that are commonly used in irrigation systems.
 Atmospheric
Vacuum Breaker: The Atmospheric Vacuum Breaker (AVB)
is a simple device consisting of a float, which is free
to travel on a shaft and seal against an air inlet. The
poppet seals the air inlet when the unit is pressurized.
When backsiphonage occurs, the poppet drops to allow air
to enter the downstream piping and break the siphon. An
AVB protects against backsiphonage but not backpressure.
There are many restrictions to the installation of the
AVB. The AVB must be installed on the discharge side of
the last shut-off valve. Code requirements vary as to
the height the AVB must be installed, but a minimum of
six inches is usually required. The AVB must be
installed with the air inlet in a level position. No
valve of any type may be installed on the discharge side
of an AVB. Because of the installation restrictions,
most codes consider the AVB for use in non-health hazard
applications. It is not testable but may be serviced
in-line if installed with shut-offs to isolate the
valve.
 Pressure
Vacuum Breaker: The Pressure Vacuum Breaker (PVB)
consists of a single spring-loaded check valve and a
single air relief valve that opens to break the siphon
when pressure drops to one psi. Because the assembly has
a spring on top of the float, it can
be used under continuous pressure. However, it cannot be
used under backpressure applications, since the valve
will open under flow in either direction. To prevent
backpressure on the valve, it must be installed at least
12 inches above the highest piping or outlet downstream
of the assembly. Some local codes allow the installation
of the PVB in health-hazard applications. The PVB is
testable and serviceable in line.
 Double
Check: A double check valve incorporates two
spring-loaded check assemblies. In a non-flow condition,
the check valves hold one psi minimum in the direction
of flow. In a flow condition, the check valves open but
will close should reverse flow occur. Double checks
protect against backsiphonage and backpressure. However,
if both checks were to foul at the same time, backflow
through the valve could occur. Therefore, a double check
is considered a non-health hazard device and may not be
approved for irrigation applications under some local
codes. The double check is testable and serviceable
in-line.
 Reduced
Pressure Assembly: A Reduced Pressure Assembly (RP)
contains two spring-loaded check assemblies with a
hydraulically balanced differential relief valve. Should
either of the checks become fouled, the hydraulic
balance will be disturbed and the relief valve will
open, discharging the potentially contaminated water to
the atmosphere. RPs are used in health-hazard
applications where backpressure and backsiphonage may
occur. They are testable and serviceable in-line.
Other types of backflow prevention assemblies are
available, but are not typically used in irrigation
systems. In some states you must be a certified plumber
to install, service and/or test backflow preventers.
Other states allow installation by an irrigation
contractor, but must be tested by a certified tester.
Consult local codes or the authority having jurisdiction
in your area to determine what is required. If you are
interested in becoming a certified tester or trained in
the maintenance of these valves, contact your local
junior college and local plumbers training programs to
find out what programs are offered in your area.
The quality of our potable water supply is of ever
growing concern. Regulations to protect our water are
becoming stronger. It is important to understand that
backflow preventers are designed to protect our potable
water supply from pollutants and contaminants. To reduce
your exposure to liability and potential damage to our
potable water supply, you should become aware of the
requirements for backflow prevention protection in your
area. Local codes identify which device is appropriate
for specific installations.

Backflow
The term backflow means any unwanted flow of used or
non-potable water or substance from any domestic, industrial or
institutional piping system into the pure, potable water
distribution system. The direction of flow under these
conditions is in the reverse direction from that intended by the
system and normally assumed by the owner of the system. Backflow
may be caused by numerous specific conditions; but, basically
the reverse pressure gradient may be due to either a loss of
pressure in the supply main called backsiphonage, or by the flow
from a customer's pressurized system through an unprotected
cross-connection, which is called backpressure. Thus the term
backflow covers both a backsiphonage condition and a
backpressure condition. A reversal of flow in a distribution
main--or in the customer's system--can be created by any change
of system pressure wherein the pressure at the supply point
becomes lower than the pressure at the point of use. When this
happens in an unprotected situation the water at the point of
use will be siphoned back into the system; thus, potentially
polluting or contaminating the remainder of the customer's
system. It is also possible that the contaminated or polluted
water could continue to backflow into the public distribution
system. The point at which it is possible for a non-potable
substance to come in contact with the potable drinking water
system is called a cross-connection. To prevent backflow from
occurring at the point of a cross-connection a backflow
prevention assembly must be installed. However, it is important
the backflow prevention assembly match the particular hydraulic
conditions at that location and is suitable to protect against
the degree of hazard present. The particular type of backflow
preventer appropriate for specific needs will be discussed
later. First, it is necessary to understand some basic
hydraulics which govern the principles of backflow and
cross-connection control.
Pressure
Pure water at sea level weighs 62.4 pounds per cubic foot.
Thus, if the base of a cubic foot is divided into 144 one-inch
squares, the weight of the column of water one foot high
covering a square inch area would be 0.433 pounds. Or 0.433
pounds per square inch of pressure exists at the base of this
cubic foot of water. Since, pressure is measured in pounds per
square inch, the area covered at the base of a water column is
not relative to the pressure.
As a rule of thumb, it is said that a column of water one
foot high creates a pressure of approximately 1/2 pound per
square inch, or psi.
Another term used for measuring pressure aside from psi is
inches of mercury, or "Hg. This is because mercury
manometers are often used to measure pressure differentials.
However, mercury weighs 13.5 times the weight of water.
Therefore, one "Hg is approximately 1/2 psi.
Backsiphonage
Technically, if one siphons a fluid out of a container or a
pipeline, one causes that fluid to flow up over the rim of the
container or top of the pipe and then down into a lower
elevation through a piece of tubing or, in this case a piece of
pipe that is part of the distribution system. In the vernacular,
the unwanted fluid is "sucked" into the potable water
line. It is important to understand that it is not necessary for
the system main to be under a true vacuum (i.e., zero psia) for
backsiphonage to occur. All that is required is a negative
difference in pressure and a piece of tubing or pipe that is
completely full of fluid.
One of the causes of backsiphonage is a situation that arises
when a temporary shutdown of a water main--or an in-plant
pipe--becomes necessary for repairs. If the repair is at some
point other than that of the highest point in the system, then
there will be a potential for a reverse flow if one of the lower
points of service is opened while the main valve is closed.
Under this condition the water in the internal piping system
will drain to the open valve or point of water use, siphoning
anything it may be in contact with at the time.
Backpressure
Due to the length of a main distribution pipe, the several
pipe fittings and the normal elevation of the service above the
distribution main, the pressure gradient within a service
decreases as the point of discharge becomes further and further
from the main. Consequently, in many processing plants or
high-rise buildings there is need to use a booster pump; or, in
many instances, a recirculating pump. The use of an in-plant
pump can easily increase the in-plant pressure above that of the
supply main. Thus, if there is any pathway whereby this
pressurized industrial water may enter the potable distribution
system, there will be a hazard as the result of this
backpressure.
Types of Cross-Connection
A cross-connection is any actual or potential
connection or structural arrangement between a public or private
potable water system and any other source or system through
which it is possible to introduce into any part of the potable
system any used water, industrial fluids, gas, or substance
other than the intended potable water with which the potable
system is supplied. By-pass arrangements, jumper connections,
removable sections, swivel or change-over arrangements or other
"temporary" arrangements through which backflow could
occur are considered to be cross-connections
General progress in the elimination of cross-connections has
been very slow. It required over a score of years for various
water, health and fire insurance representatives to understand
that no direct connection should be made between the potable
water supply system and polluted auxiliary water supplies. It
was not until the Chicago amoebic dysentery outbreak of 1933
that a general move toward correction of plumbing hazards was
given impetus. And, since that time the recognition of a
backflow prevention program and its value has been very slow,
until about 1970.
There are two basic types of cross-connections: a direct
cross-connection and an indirect cross-connection. The
difference between these two types of cross-connections is very
simple. A direct cross-connection is subject to backpressure (as
shown above); an indirect cross-connection is not subject to
backpressure. An example of a direct cross-connection would be
the make-up water line feeding a recirculating system. An
over-the-rim inlet used to fill an open receiving vessel would
be an example of an indirect cross-connection. Backpressure
could not be introduced into the supply line with this type of
connection.
Degree of Hazard
The type of backflow preventer used to prevent backflow from
occurring at the point of a cross-connection depends on the type
of substance which may flow into the potable water supply. A
pollutant is considered to be any substance which would affect
the colour or odor of the water, but would not pose a health
hazard. This is also considered a non-health hazard. A substance
is considered a health hazard if it causes illness or death if
ingested. This health hazard is called a contaminant.
Sewage and radioactive materials are considered Lethal
Hazards. This is because of the epidemic possibilities
associated with sewage and the tremendous dangers associated
with radioactive material.
Types of Backflow Preventers
There are five distinct types of piping or mechanical
assemblies which are considered to be backflow prevention
assemblies; but, it must be stressed that these are not all
equally acceptable as protection against all types of hazards.
The degree of hazard must be assessed along with they type of
cross-connection present to determine which type of backflow
prevention assembly is most suitable to the situation.
Air Gap
An Air Gap is a physical separation of the supply pipe by at
least two pipe diameters (never less than one inch) vertically
above the overflow rim of the receiving vessel. In this case
line pressure is lost. Therefore, a booster pump is usually
needed downstream, unless the flow of the water by gravity is
sufficient for the water use. With an air gap there is no direct
connection between the supply main and the equipment. An air gap
may be used to protect against a contaminant or a pollutant, and
will protect against both backsiphonage and backpressure. An air
gap is the only acceptable means of protecting against lethal
hazards.
Atmospheric (non-pressure) Type Vacuum Breaker {AVB}
The AVB is always placed downstream from all shut-off valves.
Its air inlet valve closes when the water flows in the normal
direction. But, as water ceases to flow the air inlet valve
opens, thus interrupting the possible backsiphonage effect. If
piping or a hose is attached to this assembly and run to a point
of higher elevation, the backpressure will keep the air inlet
valve closed because of the pressure created by the elevation of
water. Hence, it would not provide the intended protection.
Therefore, this type of assembly must always be installed at
least six (6) inches above all downstream piping and outlets.
Additionally, this assembly may not have shut-off valves or
obstructions downstream. A shut-off valve would keep the
assembly under pressure and allow the air inlet valve (or float
check) to seal against the air inlet port, thus causing the
assembly to act as an elbow, not a backflow preventer. The AVB
may not be under continuous pressure for this same reason. An
AVB must not be used for more than twelve (12) out of any
twenty-four (24) hour period. It may be used to protect against
either a pollutant or a contaminant, but may only be used to
protect against a backsiphonage condition.
Pressure Vacuum Breaker {PVB}
The PVB includes a check valve which is designed to close
with the aid of a spring when flow stops. It also has an air
inlet valve which is designed to open when the internal pressure
is one psi above atmospheric pressure so that no non-potable
liquid may be siphoned back into the potable water system. Being
spring loaded it does not rely upon gravity as does the
atmospheric vacuum breaker. This assembly includes resilient
seated shut-off valves and testcocks. The PVB must be installed
at least twelve (12) inches above all downstream piping and
outlets. The PVB may be used to protect against a pollutant or
contaminant, however, it may only be used to protect against
backsiphonage. It is not acceptable protection against
backpressure.
Double Check Valve Assembly {DC}
The Double Check Valve Assembly consists of two internally
loaded, independently operating check valves together with
tightly closing resilient seated shut-off valves upstream and
downstream of the check valves. Additionally, there are
resilient seated testcocks for testing of the assembly. The DC
may be used to protect against a pollutant only. However, this
assembly is suitable for protection against either backsiphonage
or backpressure.
Reduced Pressure Principle Assembly {RP}
This assembly consists of two internally loaded independently
operating check valves and a mechanically independent,
hydraulically dependent relief valve located between the check
valves. This relief valve is designed to maintain a zone of
reduced pressure between the two check valves at all times. The
RP also contains tightly closing, resilient seated shut-off
valves upstream and downstream of the check valves along with
resilient seated testcocks. This assembly is used for the
protection of the potable water supply from either pollutants or
contaminants and may be used to protect against either
backsiphonage or backpressure.
Double Check Detector Assembly {DCDA}
The DCDA is composed of a line-sized double check valve
assembly with a specific bypass meter and meter-sized double
check valve assembly. The meter registers accurately for very
low flow rates to detect any unauthorized use of water. This
assembly is used when the protection of a double check valve
assembly is required, yet where the added requirement of
detecting any leakage or unauthorized use of water exists.
Normally these assemblies are reserved for use on fire sprinkler
lines.
Reduced Pressure Principle Detector Assembly {RPDA}
The RPDA is very similar to the double check detector
assembly except that the RPDA is designed for situations
requiring the protection of a reduced pressure principle
assembly and detection of unauthorized use of water or leaks. As
with the DCDA, the bypass meter must register accurately at low
flows. This assembly is normally used on fire lines which may
contain contaminants, such as anti-freeze additives or foamite.
The chart above shows which type of assembly is acceptable
for use under certain hydraulic conditions and degrees of
hazard.

Learn Which
Backflow Preventer to Use
and Why to Use Them!
|
| In most homes the landscape
irrigation system and the potable water system are one and the
same -- there is no separation. Here's where the danger comes
in. Sprinkler lines lay in gardens and lawns that are often
sprinkled with weed killer, pesticides, and other poisons.
Irrigation systems occasionally draw water inward (backwards).
This phenomenon is known as a siphon or backflow. Backflow can
result in contaminated water at a tap inside the home. Is there
any wonder why the building code requires that all outside
irrigation lines have some sort of anti-siphon protection?
Backflow
can be defined as the unwanted reverse flow of any liquid,
solid or gas in a piping system. In an irrigation
application, this means that water within the irrigation system
may find its way back into the potable (drinkable) water system
during a backflow incident.
A backflow
preventer is a device designed to prevent potable
water from being contaminated with non-potable water in the
event a cross-connection exists during a condition of backflow.
There are two main types of
backflow: Back Pressure and Back Siphonage.
Back
pressure is when pressure downstream of the device is
greater than the pressure upstream. Water hammer is an example
of backpressure.
Back siphonage occurs when a
vacuum is created upstream and water gets literally sucked
backwards. An open fire hydrant, or water main break can cause
back siphonage. Not all backflow devices are created equal. |

Backflow
Prevention Assemblies Protect Against Contamination
by Terry Nelson |
Backflow
Preventers
These are a must in all sprinkler systems if you want to protect
yourself from physical harm as well as the law. The backflow
preventer prohibits the contamination of your personal water
supply. And while the anti-siphon valve already has such a
stabilizing mechanism built in, the Globe and Angle Valve are
incomplete in such regards. Thus, if you have selected to
install a Globe or Angle Valve, you must also choose one of the
following backflow preventers. |
 |
Atmospheric
Vacuum Breaker
It is Sprinkler Warehouse's recommendation
that you avoid this type of backflow device since it is
extremely unreliable!
If you make this selection, be sure to buy one unit per
control valve located on the landscape. They are the cheapest of
backflow preventers, however, almost all city codes do not allow
the use of this type backflow device for sprinkler systems.
If you have a lot of control valves, specifically 6 or
more, it tends to cost you more in the long run, and a pressure
vacuum breaker becomes the more practical choice. AVBs must be
installed at least 6" above the highest sprinkler head in
the zone that they operate. |
|
Pressure Vacuum
Breaker
Comparable in function to the AVB but only requires the
installation of one breaker for the entire irrigation system.
Accordingly, the number of control valves on your property is
irrelevant. It should be mounted on the mainline leading to all
control valves, 6" above the highest sprinkler head.
This is one of our Best Selling types of
backflow devices. |
 |
Reduced Pressure
Backflow Preventer
The best that money can buy, this preventer is almost always
found in a commercial sprinkler system and can be a great
compliment to a residential system as well. The device allows
for the application of fertilizers or other chemicals into the
irrigation system, a function that no other preventer performs.
Used mostly in dangerous situations, it should be set up 12"
above ground. |
|
|
Double Check
Backflow Preventer
This preventer allows for the flow of pure water that is not
susceptible to contaminants in the air. Though this device does
not allow for the application of chemicals into the irrigation
system, it is cheaper in comparison to the RPBP. Typically, it
is installed beneath the ground in a vault and sometimes in
basements, a tactic that protects them from freezing.
This is one of our Best Selling types of
backflow devices. It works great when installing the backflow
device in a basement or below grade.
The Problem With Double Check
Though the preventer is built with two check valves, in the
instance that dirt or other objects gets stuck in one valve, it
is likely that the same will happen to the other valve at the
same time. Thus, the two valves could fail at the same time, in
turn causing the water supply to be contaminated by noxious
substances. |

Sensors

Sensors
The ability to water only when necessary is the ultimate goal of efficient irrigation scheduling. Today's technology allows for installation of sensors which can measure soil moisture, rainfall totals and even shut systems down in freezing weather. |
Rain Sensors
These units are mounted in a location exposed to normal rainfall, but outside the watering spray of the sprinkler system. There are different designs, but most have settings that allow some sort of measuring to take place. Rain will cause the system to remain off during or after an event if sufficient rainfall is measured. The settings can be adjusted so a light shower will not effect the system operation or eliminate a scheduled watering when rainfall is not sufficient to make up for a normal application.
|
|
Freeze Sensors
This type of sensor is very popular in commercial settings where ice on walkways or streets can cause liability. Freeze sensors have a place in the residential garden as well. Watering before or during heavy freezes can create problems with ice-laden shrubs and trees as well as creating the same liability concerns the commercial user experiences. The freeze sensor is mounted on an outside wall in a location most likely to experience freezing conditions. It will interrupt the signal to the control valves when temperatures fall below freezing. When conditions improve, the system will return to normal operation

How to Connect
Your Sprinkler Head
to the Underground Pipe
There are a few
different ways to connect a sprinkler head to the underground piping. You can
use Hunter Pre-Made Swing Joints, you can make your own Swing Joints using Swing
Pipe Fittings and Swing Pipe, or you can use Cut-Off Nipples. All three methods
will result in the sprinkler head being connected to the pipe, however, swing
joints result in the ability to quickly raise or lower the head if needed in the
future. Once you understand the benefits of swing joints, you will never use a
cut-off nipple again!
 Hunter
Pre-made Swing Joints: If you've experienced trouble installing
sprinklers to correct finish grade because you can't find the right
riser length...if your pipes are buried in shallow trenches and you want to
retrofit to taller pop-up sprinklers...if you're having difficulty raising
sprinklers buried under inches of built-up thatch...if you want to be sure when
a sprinkler has heavy equipment rolling over the top it can easily be properly
readjusted...then here's the perfect solution. Also, the Hunter Swing Joint is
the simple way to adjust a hard-to-place sprinkler to its proper height and
position in mere seconds. This versatile creation is available in two different
versions - for new installations or for retrofits - and, with a simple twist of
the wrist, either can install to virtually any position, making it the ideal
option to add to sprays and rotors at any time. This is an innovative product
you won't want to pass up!
One end of the swing
joint screws into the bottom of the sprinkler head and the other end screws into
the pipe fitting underground. The swing joint consists of a piece of flexible
pipe with a swivel elbow on each end which allows the sprinkler head to be
raised up or down and moved left or right to a perfect position and height.
Therefore, it makes installing the sprinkler heads quick and easy, and in the
perfect position. Moreover, it allows you to come back and quickly and
easily raise or lower the head if the ground settles, you decide to add more
mulch, or if a car or mower runs over it and moves it out of position. Since
these Hunter Swing Joints are pre-made, installation of the sprinkler
heads is very quick and easy.
Swing Pipe Fittings and
Pipe: This method of attaching the sprinkler head to the pipe
results in a similar attachment as described above with Hunter Pre-Made Swing
Joints, however, you need to manually put the swing joints together using the
swing pipe and fittings. These swing joints do not have the swivel elbows on
each end but do result in a lot of flexibility due to the flexible pipe used.
The fittings are inserted into the ends of the flexible pipe.
One end of the swing joint
screws into the bottom of the sprinkler head and the other end screws into the
pipe fitting underground. Allows the sprinkler head to be raised up or down and
moved left or right to a perfect position and height. Therefore, it makes
installing the sprinkler heads quick and easy, and in the perfect position.
Moreover, it allows you to come back and quickly and easily raise or lower
the head if the ground settles, you decide to add more mulch, or if a car or
mower runs over it and moves it out of position.
PVC Swing Joints:
This method of attaching the sprinkler head to the pipe results in a similar
attachment as described above with Hunter Pre-Made Swing Joints, however, these
PVC Swing Joints are only used on large rotors with a inlet of 3/4" or 1".
Excellent for use under sprinkler heads anywhere high quality installation is
required. Allows sprinkler height and angle to be adjusted, and protects under
head piping against damage. O-ring seals provide leak-free joints, ideal for
valve-in-head applications.

it allows you to come back and quickly and easily raise or lower the head if the
ground settles, you decide to add more mulch, or if a car or mower runs over it
and moves it out of position. However, this is an expensive swing joint and
is typically only used in commercial applications.
Cut-Off
Nipples:
This method is the oldest method of the three method described on this page. It
requires you to connect the sprinkler head to the pipe using a non-flexible,
straight piece of threaded nipple which you cut to the correct height. This
Cut-Off Nipple is sometimes referred to as a riser. Made of durable poly
plastic, these 6'' long nipples are handy because you can cut them off to the
desired length. No need to purchase many different lengths. A great value
because one nipple can provide 3 or more short ones. The flexible poly can act
as a shock absorber if the head is jarred, preventing breaks in many cases. The
drawback to using these cut-off nipples is that you have to measure and cut the
nipple the right height and if you mess up you have to cut another one until you
get it the right height. If you want to raise or lower the sprinkler head in the
future, you will have to dig up the sprinkler head and remove the old nipple and
cut another one the new height. However, these are less expensive than the swing
joints.

Sprinkler Heads
|
|
Sprinkler Head Type
The types of heads utilized on a specific project are determined by the dimensions of the area being covered, the water pressure available for operation, and a variety of other factors. Choose between a spray or rotor. |
|
Spray Heads
Spray heads spray water in specific circular patterns and can be changed at your discretion. Spacing between sprinklers varies depending upon the specific nozzle that is installed in the head. To operate efficiently, units should rarely be spaced further than 15 ft apart and should be supplied with 20-30 PSI of water pressure. Ideal for smaller, fragmented, hard-to-reach areas, these heads discharge 2-3 times the water of a rotor. |
| |
Rotor
Rotor heads also disperse water in circular patterns. However, these are used to cover larger areas of un-interrupted space. Small rotors tend to cover radii of 15-52 feet and large rotors can be designed to cover radii of up to 100 feet. To operate efficiently, rotors need to be supplied with more water pressure than spray heads. The PSI level should approximately equal the space between each installed unit. There are two basic types of rotary heads, categorized by the mechanism that causes the sprinkler to rotate. These types are impact rotors and gear-driven rotors. |
| |
|
Impact Rotors
These rotors move in a circular pattern and slowly water the entire area within that circle. Impact rotors are also available as part-circle sprinklers that can be used in corners or along walks or streets. The impact rotor is typically cheaper than a gear-driven rotor and may provide the most uniform coverage of all sprinklers. However, the largest problem with impact sprinklers is their high maintenance requirement. As an impact sprinkler is activated, it rises out of its assembly to approximately 4 inches above the turf. During the time the sprinkler is in operation, this open cavity in the sprinkler case becomes an open catch for all trash, mud, clippings, insects, and types of yard debris. This debris is washed into the mechanism during the normal operation of the head. Periodic maintenance is required to keep sprinkler canisters clean and to keep dirt and debris from causing damage to the mechanism. |
| |
|
Gear Driven Rotors
With these sprinklers, water turns a small turbine (water wheel or fan) in the base of the unit, which drives a series of gears that cause the head to rotate. The gear drive mechanism is sealed from dirt and debris and operates without the irritating clatter of impact sprinklers. The gear driven design has dominated rotary sprinkler sales in the irrigation industry for some time, in both residential and commercial sites. Although the individual gear drive rotor unit is several times more costly than a spray head, its wider spacing capabilities means fewer heads are needed to cover a given area. |
 |
Sprinkler Head Design
Once you have chosen either a spray or a rotor, you must next determine what sprinkler style will best meet the needs of your irrigation area. Choose between either a pop-up or fixed design. |
|
Pop-Up
This is the most common design selected by consumers. Installed below the ground, the sprinkler head remains out of sight while inactive. Accordingly, it will not corrupt or compromise the aesthetic beauty of your landscape. Furthermore, there wont be any pipes sticking out of the ground for you and your children to either destroy or trip over. Once the sprinkler system is turned on, a small portion of the head will emerge above the surface to disperse water to the irrigation area. |
| |
Fixed (Shrub)
Installed above the ground on a riser, this sprinkler design should be utilized if you need to provide water to high-reaching plants. They are sometimes cheaper than pop-ups, but we do advise you that this is not the best selection for an area in the middle of the lawn if it can be avoided. Pop-Ups can usually be designed to perform similar functions and will mitigate the potential problems caused by shrubs (risers) as described in the above paragraph. If a shrub is indeed needed, we encourage you to install them in the corner areas of the landscape not usually walked through. |

By Katherine Woodford
Indian summer, leaves are changing .
. . winter can’t be far away. This has been a tough year for
contractors, especially for those who do winterizations. The weather
didn’t break for most parts of the northeast and central states
until mid-April. Because of this long layoff, they have had to crunch
to get the work they had on the books done and to bring in new
business. Hopefully, the weather will cooperate and they can work late
into the fall.
Professional contractors are already
beginning to think about scheduling their winterization programs, so
as to avoid a crunch for time as the temperatures drop. Some
contractors have found a way to decrease their stress level, and to a
degree, stave off winter. They use one of the best-kept secrets of
winterizing, the automatic drain valve.
While an insignificant part of the
six billion dollar a year industry, automatic drain valves can play a
significant role in conserving time and labor for the contractor, and
helping his customers at the same time. The valve enables contractors
to start installing sooner in spring and work later into the fall
installation season.
The drain valve works very simply.
Most use a pressure-activated rubber valve that closes when the psi
reaches 9 or 10. When the zone cycle ends and shuts off, the resilient
rubber valve reopens and a portion of the water drains out, providing
valuable freeze protection.
Automatic drain valves are not new
to the irrigation industry. Lloyd King invented and introduced them to
the market in 1970. His son, Herb King, continues production under his
company’s name, King Safety Products, after revising the drain in
1992. Seven years ago, Tom King of Tom King Harmony Products, another
son of Lloyd’s, came up with a new automatic freeze drain design. He
calls it the Harmony Drain.
“The contractor doesn’t need a
gravel sump anymore unless installing in extreme clay conditions,”
explains Tom King. “All soils are suitable for drainage. We
recommend mounting lateral line drains at a 45-degree angle to keep
any dirt that may be in the system out of the drain.”
“In the spring there is always a
chance of contaminated water running back into a pipe,” says Herb
King, “but these drains are designed with a backflow check; water
comes out, but can’t go back in. The earth wicks the water out of
the pipe, but you don’t want the dirt going back in.”
Freeze drains are used on both
polyethylene and PVC pipe. They are installed on the main line, the
lateral lines, the middle of the lines, the end of the line and any
additional low spots along the pipe. Three per zone is a typical
installation. Settling some concerns over whether drains will work
long-term, Herb King advises that there are systems over thirty years
old still being protected with King Drains. “It is the only auto
drain with both critical features, backflow check and dirt
intrusion.”
The mainline automatic freeze drain valves are designed to handle up
to 1200psi and the lateral line automatic freeze drain valves are
designed to handle up to 1000psi, to eliminate damage to the drain
caused by the water hammer.
The Harmony drain has a built in
self-cleaning operation; when the pipes start to fill, a small
precision-ground PE rubber ball bounces around inside the automatic
freeze drain valve, eliminating any dirt in the system from clogging
the freeze drain. Both drains have the wicking action drain pad that
protects against root intrusions and sharp rocks.
There are several advantages to
making automatic freeze drains a standard part of your systems. You
can advertise your systems as automatic drain systems. In addition,
you can also offer a 100% warranty against freeze damage. Not only do
you offer your client security against freezing pipes, it is very
profitable as well.
In writing this article, it was
interesting to note that as we telephone-traveled from east to west,
we found that in certain areas of the country they use automatic
freeze drains extensively. In other areas they’re not used at all,
and still others use them in “special circumstances.” In many
cases, whether automatic freeze drains are installed or not often
depends on who trained the contractor in irrigation installation. This
explains why there may be entire regions in a state that do or do not
use automatic freeze drains. The predominant number of contractors
using automatic drains was in the Midwest, and where wintertime
freezing frequently occurs.
Another advantage is in
winterizations. Automatic drains give your customers a longer fall and
an earlier spring watering season, protecting their systems against
premature freezing. You can blow out more systems in less time because
the lines have already been drained. With this time savings, you are
able to install systems later into the season, thereby avoiding the
normal crunch, when everyone wants their systems winterized at the
same time.
In some areas of the country,
contractors are not blowing the systems out if they have installed
automatic freeze drains. As they explain how to operate a new system
to the homeowner, they also explain how to drain the main line when
the system is ready to be shut down for the winter. They give the
homeowner a handout explaining the steps for shutting the system down
and bringing it back up in the spring.
“Most of my customers like this
idea,” says Mark Alexander, owner of Tri-City Sprinklers in Grand
Island, Nebraska. “If they know a hard freeze is coming, they can
drain the system, shut it down, and then, if in the next week or so it
warms up and they want to water, they can bring it up by themselves,
without having to pay me for service calls. The following spring, they
can turn it on whenever they are ready to use it. They like that
independence.”
 Brandon
Phelps, owner of Magic Lawe in Bountiful, Utah, says, “It doesn’t
take an extra minute on each line to install automatic drains. I
guarantee my work for three years, and I just like doing it right the
first time.”
In New Jersey, a spokesman for
Princeton Irrigation stated that unless someone specifies it,
automatic drains are not installed, except where there are exposed
risers. In Pennsylvania, a contractor who installs in a very rural
area feels automatic freeze drains are a “good thing to use” but
his clients have a low price in mind for what they want to pay for a
system and he can’t include automatic freeze drains. He blows all
his systems out, even those with automatic freeze drains, as a safety
measure.
Ted Schellhase, owner of Lake Front
Landscape in West Point, Utah, says he installs freeze drains in
special circumstances. He uses polyethylene pipe and he says that when
coming down a hill he will place a drain past the last sprinkler at
the lowest point. He blows all his systems out.
“I advertise my systems as
self-draining,” says Jerry Lamner, owner of R & L Sprinkler in
Grand Island, Nebraska. “This is upselling, but most reputable
companies in our area install freeze drains. Extending the season is
not necessarily a factor; the big factor is keeping the backflow from
freezing.” Lamner does not blow out his customer’s systems.
Instead, he shows them how to relieve the pressure, preferring to save
his clients money on service calls.
“Installing automatic freeze
drains is standard procedure with my irrigation systems,” explains
John Yowell, owner of Modern Underground Irrigation in Lincoln,
Nebraska. “I don’t give my clients a choice. I give them an
instruction sheet for draining the system in the winter and have had
positive responses. They know how much money they are saving in
service calls, and I like not having the stress in the fall and spring
scheduling shut downs and start ups.”
The majority of contractors
interviewed across the nation still blow out their clients’ systems.
Some were not aware of the existence of automatic freeze drains; some
had heard of them but did not have enough information to try them;
others had heard about them but had concerns about failure and felt
that if they failed, it would be too late, pipes would be frozen.
Automatic freeze drains are still
irrigation’s best-kept secret. It’s time they came out of the
closet! Add security to your irrigation systems for your customer’s
peace of mind. Upgrade the systems with automatic freeze drains to
rise above the competition. Don’t be afraid to ask questions to find
out if they are conducive to your area’s climate. Learn about the
changes and advancements that have been made since the ’70s. With
this knowledge, you can easily make the systems you install state of
the art.

Swing Joint
The joint provides the sprinkler with flexibility so it can be adjusted. It also helps to protect it from being crushed. It is primarily used in aboveground irrigation systems on public grounds such as parks.
Crimp Clamp
A circular metal band which is clamped by a special tool to help it provide leak-proof seal.
Goof Plug
Use to plug a tiny goof hole in polyethylene hose. Can withstand an operating pressure of 60 psi. |

Controllers
|
|
Controllers
Also referred to as timers, these devices are responsible for turning an automatic irrigation system on and off. Controllers can range from very simple to quite advanced computer systems which offer many powerful features. One should base their selection on the nature of their system. For example, if you have a six-zone irrigation system in place, make sure to select a controller with a six-position capacity. A controller is typically either mounted on a wall or in a protective pedestal. |
 |
Electromechanical Controllers
Offer exceptional reliability because of their rudimentary electronic components and design. Simply turning dials or flipping switches will set the controller that is rarely affected by power outages. A potential drawback of such a device is the inability to provide independent scheduling to accommodate complex watering requirements.
|
Electronic Controllers
Electronic controllers can be programmed to water different parts of the lawn based on each plant's watering requirements. Landscape can be watered at different rates or frequencies due to sun exposure, poor drainage or soil conditions. Ideally, these controllers would be reprogrammed as the lawn matured or the seasons changed. |

Control Valves
|
|
Control Valves
These devices are used to turn a sprinkler system either on or off. Though manual valves are available, most modern systems include valves that are connected to a controller for automatic operation. We offer three different types of control valves: a globe valve, an angle valve, and an anti-siphon valve.
IMPORTANT: A BACKFLOW PREVENTER MUST BE BOUGHT OR PROVIDED SEPARATELY TO COMPLETE THE PROPER INSTALLATION OF A GLOBE OR ANGLE VALVE. IF YOU PURCHASE AN ANTI-SIPHON VALVE, THE BACKFLOW PREVENTER IS ALREADY BUILT-IN AND AN ADDITIONAL ONE IS NOT NECESSARY. |
Globe Valves
Commonly purchased for use in commercial irrigation systems. It is typically installed beneath the ground, and to your convenience, is available in almost any size. They are relatively cheaper than the angle and anti-siphon valves. A backflow preventer MUST be bought or provided separately.
|
Angle Valves
Offers the same features as the aforementioned Globe Valve but is constructed with an additional inlet at the base of the valve. This creates a 90-degree angle between the inlet and outlet pipes, a construction that moderates the pressure drop that may occur across the valve. If this is indeed a concern for you, the angle valve is a better choice than the globe valve. Again, a backflow preventer MUST be bought or provided separately. |
Anti-Siphon Valves
This is quickly becoming the most popular choice amongst consumers, especially since some building codes are beginning to require their installation in irrigation systems. The function of this particular item is best explained by describing the problem it solves: -The Siphon Effect-. The backflow preventer is already built in.

Selecting Valves for Dirty Water Applications
|
|
If you're working on sites where the primary water source is lakes, ponds, streams or effluent, it's very likely that you deal with "dirty" water. Since the dirt and debris from this kind of water can choke an irrigation system, picking the right equipment is vital and nowhere is this more vital than in the selection of the correct remote-control valves.
When you select a remote-control valve for a dirty water application, make sure it has filtration features incorporated into the valve by the manufacturer. This is a very important , because not all valves have filters and the area on top of the valve diaphragm and the solenoid area is extremely susceptible to damage from fine particles of dirt and debris. The best method for filtration manufacturers employ to prevent dirt from contaminating the valve and interrupting operation is the "self-flushing" screen.
A filter or screen that is self-flushing prevents water containing dirt and debris from entering the top of the diaphragm and the solenoid. Located on the bottom of a valve's diaphragm or inserted into the side of the valve body with a tube connected to the base of the solenoid, the screen or filter positioned in the stream of water running through the body of the valve. The water flow continuously flushes the filter screen, dislodging particles and debris before they can accumulate and clog the filter.
One manufacturer's valve, which is particularly effective in dirty water, is the Rain Bird series of scrubber valves. This series of unique valves have a scrubbing action, which occurs every time the valve is opened and closed. The fingers of the plastic scrubber removes dirt and debris by scraping the stainless steel filter screen clean as it moves up and down with the diaphragm. The action constantly breaks down debris to prevent build-up and clogging. |

Emergency Valves
These should be installed adjacent to your point of connection with the water supply. Its purpose is to enable you to operate on the mainline or irrigation valves without disrupting the supply of water to your home. There are two basic types for you to choose from: The Gate Valve and The Ball Valve. The Ball Valve is more expensive, but it typically lasts for longer periods of time. |
