    started up a residential system utilizing a lake pump. blew out system in fall and everything functioned properly. reconnected pump filter, primed pump(definitely pumping, got soaked), started test program, no heads come up. system has master valve. checked voltage from controller, mv voltage good. resistance good. any ideas would be appreciated :)

    If the controller is working and firing both the MV and the individual valves but nothing is popping up then obviously you have a problem with the master valve. Try firing it manually (at the valve) and see if you can get water to your main line.

    Make sure there is no isolation valve you've not opened...some valves fail
    open/closed...I'd check the solenoid port for flow first after Purps suggestion.
    Age of system a big part of this...which is why I spec brass valves for mstr.,
    they work so hard! Let us know before we suggest chimney cleaning.

    i manually turned selenoid to open, no change. strange thing, only head to show a sign of water is 1 1800 in zone 4. won't pop up, but spits out a little stream about 4 inches. thought at first it might just take a bit to fill all zone pipes (bout 3 acres, 11 zones)let zone run bout 1.5hr, nothin but the trickle. :(

    if the pump were damaged, would it still put out water(took of cap on top and water was shooting 15' in air.

    Sounds like the pump is not primed. Or it lost prime.
