| Backflow
Prevention |
| |
Every
irrigation system is supposed to have a proper backflow
preventer. These devices prevent water from the irrigation
system from flowing back into the drinking water supply.
We have gone to great lengths to design the FertiGator to be
safe for humans and the environment. We have built several
backflow redundancies into the injector, making it no more
dangerous than the irrigation system itself. |
- |
The
fertilizer source is isolated from the water system by
a special 3-way solenoid valve so that there is no way
the fertilizer will siphon out of the container into
the water system in the event of a backflow event and
backflow preventer failure. This has been a problem
with prior attempts to deliver the benefits of
fertigation to the residential market |
|
|
- |
The
FertiGator cannot pulse if there is no water pressure,
such as when there is a backflow event. No fertilizer
can be injected once the pressure begins to drop even
if the system is attempting to operate. |
|
|
- |
Fertilizer
is injected at only one milliliter per pulse. The
miniscule amount of fertilizer in the line at any
given time should not pose a significant health hazard
to anyone. This risk is approximately the same as a
puddle above a sprinkler head containing recently
applied chemical. |
|
|
- |
Even
if there is pressure in a stagnant situation so that
the FertiGator will pulse, the FertiGator will
actually reduce the pressure in the line preventing a
backflow across a PVB backflow preventer. |
|
|
- |
If
our valves should fail whether mechanically or due to
an electrical failure, they will fail closed so that
no fertilizer can enter the sprinkler system. |
| |
|
It
is very important to use the proper backflow preventer.
We believe that it is unlikely, however, that there
will be a contamination of any significance from the
FertiGator if the wrong backflow preventer is used.
Which type is required is determined by State and
local law, and vary from the high hazard reduced
pressure backflow preventer (RP) or pressure vacuum
breaker backflow preventer (PVB), to the low hazard
double check valve assemblies (DC) or anti-siphon
valves (ASV).
We have not reviewed the laws of all of the States and
municipalities and make no representation as to which
backflow preventer is required in any particular area.
We are in the process of educating the governmental
authorities about the features and benefits of the
FertiGator. If you have any questions from local
officials, please have them call Ned Lips at
1-877-337-8442 ext. 6 for more information. |
