In a newly installed system, one of the Orbit jar-top valves just will not work. I've tried everything I can think of, short of digging it up and replacing the whole thing. I've swapped out ALL the replaceable parts (diaphragm, spring, solenoid, stainless tube) to no avail. I've tested to make sure I have voltage (which I do: about 26 V). Another valve does work. By opening the bleeder screw, water does flow to the sprinkler heads (so I can operate the system manually). Right now, after researching how these sprinkler system valves work, I think the bypass tube/conduit, that is 'opened' by the solenoid, must be plugged. I tried blowing it out with compressed air, but no change.
Before I go to the trouble of digging it up and replacing the valve body, is there anything else I should try? Any other way to clean the small conduit tube when the valve body is in the ground? Anything else that might be causing the problem that I might have overlooked?
Thanks much!
