Sprinkler System

[Riverratpete]

I have a Toro inground sprinkler system. I now have 3 "dead" zones. I have downloaded the trouble shooting guide off the net, checked the wiring, etc..nothings jumping out at me so i'm thinking it may be the cylinoid..how hard are they to replace? any other ideas?

My solenoid valves are hard piped in, but I wouldn't think it would be too hard to cut and splice some new valves & pipe fittings.

Also on my system there is a manual on/manual off valve for each zone. If you have that, it would be a good idea to try that first to isolate the solenoid / wiring as the problem.

They screw right in to the valve assy.

Before you buy one, swap one from a zone that you know works and try it first to make sure it is indeed the solenoid.

If you have three that went bad at the same time I would guess its a problem with your common wire. Are all three valves that are dead in the same valve box? Like was mentioned before some Toro valves have a flow control that could be turned off at the valve...it isn't impossible for three to go at the same time but would be one heck of a coincidence. Anyway for you to take a picture and post it?
