Hell Gents and Ladies,
I am attempting to self-diagnose my Toro Sprinkler system. I have one station that fails to turn on (station 1) using the controller. I have no way to test wires, so I decided to start with the things I could test/replace.
At the valve for this station, if I manually turn it on, the station functions fine. I have been manually turning the station on an off this week to water that area of my yard.
My first "guess" was the silanoid, so I ordered a replacement. This did not fix the issue, same behavior. In my toro controller, I have 6 Zone Modulars in the controller, each one has 2 wires going to it expect for the last one (which station 6 hole is empty). I moved the wire that runs station one over to station 6, enabled station 6 on the controller to test to see if the issue might be with the zone modular. This did not correct the problem either. I put the wire back into station 1.
My next question is about the value diaphragm; if I can manually turn on the water at the valve and have it work, would this eliminate the chance that it's a bad diaphragm? Does manually turning on the valve circumvent the diaphragm? Or does the diaphragm only work in conjunction with the Silianoid? Should I try replacing the diaphgram?
I'm really hoping this is a mechanical issue and not an electric one.
Thanks for any advice!
