Low Pressure and Low Flow
Typical household water supply pressures range between 30-70 psi. Typical watering device flow rates range between 0.4-5.0 gpm. This feeder can handle pressures ranging from 25-125 psi and flow rates ranging from 0.2-7.0 gpm.
Minimum Flow
.2 gpm x 60 min = 12 gal / hr
This means it will work with a system that has at least 24 of the 1/2 gal/hr emitters (2 per pocket) which is 12 pockets across the top.
Or 6 pockets across the top if you use 1 gal/hr emitters (2 per pocket).
Maximum Flow
7 gpm = 420 gph / 1/2 gal/hr emitter = 840 emitters = 420 pockets across the top (ok thats a lot of pockets).
Minimum Pressure
Can be inserted in our irrigation assembly after the timer and before the regulator so there is no need for adapters.
But also the minimum 25 psi means also can be added after the regulator inline with the irrigation tubing.
