EZ Flo EZ005-FX 5 Gallon Tank Assembly Kit

Automatic Application of fertilizers, organic Supplements, weed and insect control. Replaces all other spreaders and sprayers.

EZ-FLO Main Line Systems attach directly to your in-ground sprinkler and/or drip irrigation system. Every time you use your irrigation system, EZ-FLO releases small, precision doses of water soluble or liquid non-hazardous fertilizers into the water stream on a consistent basis. One system will feed through both sprinkler and drip irrigation zones without the need to make any adjustments or nozzle changes to compensate for water flow or water pressure.

Main Line Systems have been designed to connect directly to your irrigation system after an approved backflow prevention device. They are designed to withstand constant static water pressure present in your irrigation system. These units are constructed of heavy-walled, UV-Resistant PVC and have no moving parts making them very reliable, dependable and maintenance-free.

You Will Need A Coupling Connector; please choose the correct connector for your application when adding this item to your cart.

Features & Benefits

  • The system can be installed in minutes
  • Any liquid or water soluble fertilizer or water-borne supplement can be delivered - no pre-mixing required
  • EZ-FLO Premium Fertilizers, Organic Supplements and Premium Tested Products have been proven to provide landscape solutions
  • Simply fill the system every 4 to 6 weeks and it spoon feeds your landscape every time you water
  • Base refill frequency on desired results
  • One System Feeds All Zones Drip or Sprinkler
  • 5 Year Warranty
  • EZ005 Includes:
    • 5 Gallon Tank
    • Bypass fitting, tubing and tubing clamps
    • Pressure relief valve - rated 150 PSI (10 bars)
    • Two (2) EZ Shutoff valves Inflow and outflow shutoff)
    • Air release vent valve and tank cradle (to maintain level)
    • Tank fill valve and lower drain valve
    • Irrigation coupling connector. An EZ-FLO ball valve connector (CBV) or an approved engineered connection is REQUIRED to ensure proper proportioning for all applications. When adding to your cart in the gray box above, you can select the size of the ball valve connector that you need and can add to cart. If you already have one, then select "No coupling tee needed".

Size the Model to your Landscape

What size model you choose to order is dependent on a few factors.

What is the composition of the landscape materials?

Turf uses more irrigation water than a dense ground cover or shrubs with deeper root masses.

What products are you interested in applying through your irrigation system? Some products have higher application rates than others.

In the end, this last point is the one that is the ultimate determining factor. If you want to refill less frequently, simply go up in size. If you do not mind refilling more often, then you can get by with a smaller size than what would be recommended. The following table identifies a typical landscape configuration and sizes that can be served with each EZ-FLO main line model along with other sizing information.

Please note that coverage levels assume a 4-6 week desired fertilizer refill cycle for EZ001CX to EZ010-FX models. High capacity models (designated as HC) are designed for commercial landscapes serviced by professional maintenance companies. Property sizing for those units is based on a 2-3 week refill schedule. Growers and nurseries use other sizing metrics (pounds per square foot and PPM) which can be found in their related web pages.

Fertilizer Distribution Rates

EZ-FLO's patented flow technologies ensure that the proportion of fertilizer to water remains constant from the beginning of the cycle until the tank is depleted of fertilizer. All EZ-FLO fertigation units have an adjustable cap with four reference settings corresponding to the amount of fertilizer mixed with the water: The cap can also be set at points between these four reference settings for unlimited adjustment flexibility within the maximum and minimum proportioning rates for the cap.


  • Tank Capacity (Approx.) - Liquid: 5 Gal. (19 liters)
  • Tank Capacity - Water Soluble Fertilizer: 30-35 lbs (13.6-16.3 kg)
  • Dimensions (LWH) Inches: 28 x 10 x 13
  • Maximum Operating Pressure: 100 PSI
  • Typical Feed Ranges: 0 to 20 or 0 to 12 GPH
  • Connection Options:
    • Ball Valve Connection: Dry water soluble and/or liquid products
    • Saddle Connection with Valve: Dry water soluble and/or liquid products

Tank Sizing

The tank sizing is based on the amount of concentrated product storage that will be required between tank refills.

*The amount of water soluble fertilizer that can be loaded into this model is dependent upon the solubility of the fertilizer and following the suggested fill instructions for this unit. The range listed is the maximum tank capacity using a high quality, water soluble fertilizer. Lesser amounts may be used without affecting the proportioning performance of the unit. Due to variations in the tank fabrication process, the liquid tank capacity may vary from the listed value. Therefore published tank capacities are approximate.

EZ-FLO Systems are Easy to Install and Easy to Use

EZ-FLO Systems can be installed in minutes. We recommend that they be installed in an underground valve box but they can also be hidden under decorative rocks or housed in above ground structures when necessary. The only requirement is that they be installed after an approved backflow prevention device as determined by local plumbing code.

EZ-FLO main line systems are installed after the backflow prevention device and normally before the irrigation zone valves to allow the unit to feed all irrigation zones. A typical installation is shown here:

In this configuration, when an irrigation zone valve is turned on, the EZ-FLO fertigation unit automatically adjusts to pressure and flow and precisely meters out the appropriate fertilizer based on the water volume flowing into that zone.

EZ-FLO main line units can also be installed after the zone valve or directly in-front of a single zone valve or multiple zone valves if you want to isolate a zone(s) from the other zone(s). An example is shown to the right and could be for a larger irrigation system that services lots of open turf but the owner wants to focus on their flower beds or in the case of a municipal park, just the baseball field.

Technical Information

EZ-FLO Fertigation technology has been in development over the last ten years. As of 2007, EZ-FLO has received 9 issued US Patents and 2 International Patents covering its unique fluid flow technologies and has tens of thousands of units operating in actual field use. Our patents cover the connection couplings as well as the flow process whereby fertilizer is accurately proportioned in the tank cap for release to the irrigation water stream.

One of the unique attributes of an EZ-FLO system is its ability to precisely proportion fertilizer concentrate into a water stream in an extremely accurate manner. We call this "Micro-Dosing". Not only is the amount of fertilizer concentrate proportioned accurately but the individual fertilizer elements of N-P-K are also in consistent ratios when exiting the irrigation system from beginning of the fill cycle to the end of the cycle.

Below are actual photographs of a clear tank going through a complete "full to empty" cycle.

Many people erroneously assume that fertilizer in the EZ-FLO tank is simply diluted as it goes through an entire cycle. However as can be seen above, dilution does not really occur in the way most people think. Almost all of the dilution occurs in the tank cap where we can control it and in the irrigation line where the nutrified water rejoins the rest of the clear water.

EZ-FLO�s patented flow technologies effectively create an �invisible bladder� that separates the clear water entering the tank from the fertilizer concentrate at the bottom of the tank. As clear water is introduced into the tank, it arrives in a number of areas. Port water inlets at the top of the tank create a clear layer of water that separates it from the fertilizer concentrate. Additionally a micro-jet agitation nozzle at the bottom of the tank "gently" agitates the heavier fertilizer concentrate, keeping the resulting semi-dissolved solution at even chemical concentration levels leaving the tank. Because of this 'invisible bladder effect" there is no real dilution of thesuspended N-P-K in the tank through out most of the tank cycle. Only when you get to the end of the tank contents do the NPK percentages fall off.
