Irrigation solenoid valve restricting flow
I have a Danner Model 18 magnetic drive pump:
It sucks water out of the bottom of a 55 gallon drum and pushes it up about 5' through 3/4" PVC to a 1" Rain Bird CPF-100 in-line solenoid valve. I'm getting about 160 gallons/hr. This isn't nearly enough for my system.
So I removed the Rain Bird CPF-100 and it increased to around 720 gallons/hr, which would be plenty.
The Rain Bird valve is obviously designed for a city water supply usually ranging from 50-70psi. I assume this pump isn't producing that kind of pressure.
Do I need to look for a new solenoid valve that doesn't restrict flow so badly? Rain Bird makes something for low flow drip irrigation:
Or is there something else that I can do to make more water get through the valve I have? I noticed that in the pump's instruction sheet it says 1 1/2" Inside Diameter is the minimum hose size that should be used for maximum flow:
If I were to change the pump outlet pipe from 3/4" to 1 1/2" (or 2" since I already have it) on the outlet of the pump, would that improve my situation at all? Thanks.
