EZ-FLO Main Line Systems Feed the Entire Landscape Automatically Every time You Water

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.

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. See Backflow Information for more details on what these devices do.

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.
