mrfixit - not sure that there is a (remotely-controlled via control box) master valve. That zones 1-2 work - which are not controlled by this particular valve box - would tell me it's not an issue, plus the wiring in the box looks pretty standard (I see 1-5 channels and a common coming out). I dug sideways to the bottom of that PVC pipe to find ... a buried manual valve in the off position! Basically it was your standard plumbing size valve and handle, so I guess this PVC pipe was nothing more t...
Thanks for the insight as to what the valves do. I did as you described and can't get any water out of it. Still just a trickle coming out of the inside valve, but seemingly only when the controller has them on (this could be an incorrect assumption by me, however). I'm guessing this trickle is just a bit of back flow from the zones - again, these valves are significantly below the elevation of the sprinklers. So I guess I've got to go digging for a master valve for this box. I'm guessing it mig...
Hi guys. I recently bought a 20-year-old house here in Albuquerque, and I am now getting around to trying to troubleshoot the sprinkler system. It's a five zone system, with a relatively new controller (Hunter Pro-C). The first two channels are fine, which control the front yard. However, the backyard (three zones) does nothing. Clearly this isn't a new development, as the backyard is also completely dead (I'm trying to change this) and clearly has been for a long, long time ... across at least ...
