Richdel Valve Repair

    I have an older Rain Bird irrigation system with above-ground "jar-head" Richdel 1" valves. One of the valves only works when I open it slightly or loosen the bleed screw. When I do so it leaks water, but I get good pressure. I replaced the diaphram in that valve. Seemed to work for a while, then it went back to the open valve or bleed screw scenario. I am running the other three valves closed. They are functioning, but leaking when opened. Are there O rings and seals that should be replaced in these valves that might solve my problem? Any advice would be greatly appreciated. Thanks.:)

    With above ground valves requiring no digging and all of them leaking, I would cut them out and replace them all. Start with a clean slate.

    Try a repair with an identical valve, which you can find at home centers. Swap the guts and see what happens.

    Modern medicine. By the way the way a Texas legend passed away without much fanfare Dr. DeBakey.

    Sounds like that may be the best way to go. Thanks.

    I was able to get some friendly advice from a local irrigation supply house that is not adverse to dispensing such advice to homeowners without charging for a service call. I switched the solenoid from a working valve and (sure enough) that was the problem. I spent $7.40 for a new solenoid, tightened jar heads, bleed screws, adjusted the flow screw on each valve, and now I'm back in business.:waving:
