    Rainbird Solenoid (again)

    I didn't see this issue on any other posts, so........ when I turn a solenoid "on" 1/4 turn, nothing happens, not for any of the four of them. 1/2 turn or 3/4 turn, still no water comes out of the sprinkler heads. How can this be? It's supposed to manually turn the water on. I know the water...

One, when it "turns on" (in sequence, it is the third zone of the five) knocks/hammers unstoppingly until I shut off the zone.

    Question: what kind of automated valve to shut off feed to cistern?

    Hi, first posting after a lot of reading and learning from this forum. One thing I cant seem to figure out though: My situation: I have a well pump (Franklin/Grundfos) at about 60 meters (about 180 feet) that feeds a cistern and is activated through a floating switch in the cistern. It delivers...
