Due to the location of this valve..among tree roots.. I would like to solve its problem rather than replace. I have replaced the Diaphram and the solenoid after noticing that the low point spray head was weeping. THat fixed it for about a month now it is weepng again and nothing I do will stop it? Any ideas? It also turns on quickly but turns to the mostly off state...very slowly and it seems to be getting worse.
