Fertilizer injector to fertilize everwhere your drip irrigation reaches

A fertilizer injector is the most efficient way to feed plants. Utilizing your drip irrigation system, it delivers nutrients in liquid form directly to the roots of plants and is a fast and accurate way to feed an entire garden, landscape, orchard, nursery or greenhouse.

The need for accuracy in fertilizer dosing and the ease of use are considerations in selecting a Fertilizer Injector.

EZ-FLOW is the most economical, flexible, and easy to use. It is a best choice for smaller applications.

ADD IT Fertilizer Injector is a smaller system that works well on decks, patios, or rose gardens.

MIX RITE provides very accurate dosing and can handle multiple sones of varying size at a reasonable price. A choice of commercial organic growers.

MAZZEI is a simple, reliable injector that is commonly used on small farms for a single zone or for multiple sones that use the GPM. The injector model must be chosen for the flow and size of the specific system. Rates of fertilizer are not as accurate as the MixRite.

These units will work for backyard gardeners, commercial landscapers and small farms. Just fill the tank, either with dry fertilizer or with a concentrated liquid fertilizer, set the adjustment valve and the rest is automatic. You can see the fertilizer as it is distributed to the system.

The EZ-Flo Fertilizer Injector can connect directly to a hose bib with the included bib adapter, or connected to a main water line with an installation coupler (sold seperately). It has a low minimum flow requirement of 120 gallons per hour, but will work at a flow as low as 7.5 gallons per hour when the included flo-discs are installed. When using these discs, remember to dilute your fert mixture. The mixing ratio is much higher but not known. See flo-disc instructions that come with each unit.
Not for use under constant pressure. --For a unit to use under constant pressure see theEZ-Flo Premium 1 gallon Fertilizer Injector(below)
The Faucet Kit (171-IEZHTR) is perfect to easily switch a Hose Thread EZ-Flo from one faucet to another. Just unscrew the two connector nuts from the cap and remove the entire unit. Move the unit to another faucet, re-connect the 2 nuts and you are ready to go.

Economical, flexible and easy to use. Just fill the tank. (using premixed dry fertilizer or a concentrated liquid fertilizer), set the adjustment valve and the fertilizer solution will automatically flow when the system runs.

EZ-Flo Premium 1 gallon Fertilizer Injector

This is a 1 gallon constant pressure system that can be installed into a main PVC line using the PVC mainline couplers. The fertilizer injector can also be installed into a hose threaded connection using the included bib adapter and flo disk kit for lower flows. Maximum pressure is 100 PSI. This is the ideal unit to use if you have multiple zones and the fertilizer injector needs to be installed before the valves or timer to supply all zones.

1 1/2 gallon high pressure tank (SKU: 177-IEZPR112C)

2.5 gallon high pressure tank (SKU: 178-IEZPR3C)

4.25 gallon high pressure tank (SKU: 179-IEZPR5FX)

ADD IT INJECTOR

Line pressure forces a small amount of water into the ADD IT tank where it mixes with the fertilizer and then re-enters the mainline. There is no pressure loss through the ADD IT, but it does require a minimum of 10 PSI to operate.

30-240 GPH flow rate
1 Pint fertilizer capacity
Gallons to empty: 35
Operating pressure range: 10-100 PSI
Male Hose thread inlet and outlet

BEST FOR ORGANICS, the MIXRITE is preferred by commercial growers for its very accurate dosing and its ability to handle multiple zones of varying sizes at a reasonable cost.

Simple to install, operate and maintain--No external power needed--Shut offs on all models.
Suction tube with stainless steel screen, mounting bracket, UV and chemical resistant
3/4" MPT at inlet and outlet for all models
Excellent dosing accuracy

One of the most reliable, accurate and easy to maintain pump syle injectors. Like other pump style commercial injectors, the MixRite is powered by the water flowing through it, reliably metering the fertilizer solution into your line.The 78-IMR10SO unit injects the fertilizer at a rapid rate and is the BEST FOR ORGANIC FERTILIZERS.

NOTE: fish emulsion is never recommended for use in drip systems.

Back flow prevention is necessary for all fertilizer injectors.

FERTILIZER INJECTOR

The Mazzei is a commercial grade injector with no moving parts. There is nothing to break or to wear out. It works by suction and will draw liquid fertilizer out of almost any container. Thee Mazzei can be plumbed on a bypass for less restriction (the preferred method), or directly into a main water line. It is improtant to choose the model size carefully; too large and the unit will not draw the fertilizer at all, too small and you will restrict the flow of the system. If in doubt always choose a smaller size and use a bypass assembly. This allows you to adjust the flow through the Massei and does not restrict the system floow as much. Remember, ther are not as exacting as the MIx-Rite. You will need to experiment to get the dosages required--but once operating, the Mazzei is incredibly reliable and easy to use. All sizes have Male Pipe Threads on the inlet and outlet.

Injector, Bypass Assembly and Suction Assembly are purchased separately.

BYPASS ASSEMBLY

The Bypass Assembly is pre-made of Schedule 40 PVC with a ball valve to control the flow and unions for easy removal of the injector (for cleaning). The Assembly does not include the Injector (see product illustration in accessories listed below)--items must be ordered separately. The flow chart below indicates the flow at 50 PSI and the fertilizer draw with outlet pressure at 30 PSI and 10 PSI.
