Title: Not enough flow to be useful
Review: It is pretty sturdy even though it's plastic. And it definitely regulated the pressure, but it greatly restricted the flow. So if you need to use it for more than a minimal irrigation system, look elsewhere unless you have very high water pressure or don't mind the system running for a very long period of time. I also bought a 25 psi unit at my local Home Depot and was able to get much more flow through that one.
