Installation & Use
EZ-FLO systems take little time and effort to install.
Before you install a system you need to understand where the unit will be attached to your irrigation system. This page presents some installation alternatives and shows you how EZ it is to refill and winterize your EZ-FLO system.
EZ to Install and EZ to Use
EZ-FLO systems are simple to install and easy to refill. There is little ongoing maintenance required since the EZ-FLO systems have no moving parts. About the only thing you will need to do is to refill the tank with non-hazardous water soluble or liquid fertilizer on a periodic basis. It’s that EZ! Generally, we recommend a qualified contractor to install main-line units (to make sure that all backflow requirements are met) while the hose and drip units can be installed by homeowners. See our list of Authorized Installers under “Where to Buy”.
All fertigation units require backflow protection. FOLLOW LOCAL CODES
(Winterization will require tank removal prior to “Blowing Out” the irrigation system). See Winterizing Your EZ-FLO System for further details.
EZ-FLO offers MAXX-PRODUCTS premium fertilizers & supplements for use with your system. See the MAXX-PRODUCTS section for more information on fertilizers, pest control, and water treatment.
Determining the Connection Point
EZ-FLO main-line systems are designed to feed the entire landscape but are not limited to that purpose. A system can be installed before multiple zone valves or after a single zone valve. Installation only takes minutes for someone familiar with irrigation systems. Because of EZ-FLO’s patented flow design – the system automatically adjusts to pressure and water flow, enabling a single EZ-FLO fertigation system to feed drip as well as spray zones without having to change out any nozzles or make any modification to the tank or the irrigation system.
A simple schematic of a “before the valve” main line installation is shown to the right. Note that the connection point (EZ Coupling Connection) is before all valves so that when any zone turns on, it will proportion fertilizer with water prior to going to any zone after the connection. Note only main-line systems should be connected before the valve since anything before the valve is under constant (Static) water pressure.
In some larger landscapes, there may be a desire to isolate one or two zones away from the rest of the system as shown in the example to the right. This could be the case where an irrigation system feeds an entire park but the municipality only wants to fertilize the baseball, soccer or football fields. In other cases, a flower bed is isolated from the rest of the turf so only the flower bed is fed. Here is an example of how this is done in an “after the valve” installation. Also note that a Hose and Drip unit may also be attached after the valve.
Hose and Drip Systems are not meant to be connected to a system where the unit is under constant (Static) pressure. All pressure must be relieved from a Hose and Drip System when it is not in use!
There are three primary connection types to connect an EZ-FLO main-line unit to an irrigation system.
• Coupling Ball Valve
• Threaded Coupling Ball Valve
Please see the Couplings section for further information on coupling options and sizes.
Note: Improper installation may cause the unit not to pull fertilizer from the tank. This is NOT a warranty issue.
For detailed installation instructions please review the individual product pages.
A couple of points to keep in mind:
• Ball Valve Couplings can be adjusted to increase the amount of differential pressure allowing the unit to “pull” in this particular situation. Once adjusted the setting on the ball valve will not have to be touched again.
• Almost any water-soluble or liquid fertilizer will work with the system but results are determined by the type and quality of fertilizer applied.
