    I moved into my house a short while ago. When I moved in, the 3 zones of sprinklers in the front yard worked, and one of the three in the back worked. After a short while, the one in the back yard stopped working as well.

    I have since rewired the sprinklers, thinking that would solve the problem but it didn't. The 3 in the back yard still don't work. I tried turning them on manually but they won't come on. I'm wondering what could possibly be the problem. I assume the main line is connected properly because the one zone worked for a short period of time.

    Does anyone have a clue on how I can fix this on my own?

    Thanks,
    Robert

  3. Is your water coming from N. CA? If so I'm philosophically unable to help you but I do wish you well.

    He actually ran out of water thanks to you damming that spring upstream here in FOCO at your new place.

    Ignore the riff-raff, they actually sell shoes but are groupies. What brand controller and valves do you have?

    if it worked before and you dont have a broke pipe it is either clock, wire or valve.
    Assuming you can program the clock properly-

    The old switch-aroo

    To test clock lets say zone 1 front yard works but zone 5 backyard doesnt. Is it the output on the controler or is the module is bad. Take the zone you know works 1 front yard and wire it into the zone 5 backyard. Take the zone 5 that isnt working and put it in zone 1. Does zone 1 still fire off and when it does it is effectivly firing off the zone 5 out back?

    Will zone 5 fire off and run the front yard. then it is controler because you then determined both valves are working so it is a supply issue.

    Take apart valve make sure nothing is in it, bring a coffe cup to bail water so chit doesnt get in it. Do you have water, any heavy equipment, I once had a concrete truck crush a line so bad that water trickled. Also once the town was flushing hydrants and the psi dropped so much that it wouldnt push up the 6 heads on the zone but would get up the 4 head zones.

    find the valves and determine which one is zone 5 disconect the common and zone wire from that valve or just cut the wires halfway up. Fire off zone 1 still connected to the backyard that isnt functioning, you know it has power from earlier, use a new valve solonoid and touch it to the wires if it clicks you got power to the valve if not you have a cut or corroded wire.

    Good luck

    Are you saying that because of his political views or irrigation knowledge? I thought there was another forum for that.

    no water at all 3 rear valves smells of a bad master valve.
