Zone was running on its own, but why?

So it all is fixed and the yard is back together. The small leak I had was in another valve, the one I originally thought was the bad valve. I had taken it apart and either got some dirt in it or broke. Since I had three Toro valves that I replaced with Hunter valves I just cleaned one of them and swapped tops. Saving the other two for future repairs.

All fixed!

Some things I have learned that may help another if this ever pops up on a Google search.

  1. My valve failed because the solenoid on my Toro 254 physically broke off.

  2. Like any project take pictures of everything you take apart. This will ensure you can put it back together easily.

  3. The valve wires are all color coded in my system. Somehow I had a brain fart and didn’t realize this right away. This made it easy to see which valve belonged to the zone that failed.

  4. Harbor Freight wire tracer worked very well but you need to wear headphones which means you will need a long wire. Attaching the tracer to a long stick and slowly moving worked great for me. Using it without headphones failed.

4.1 I found it by clamping to both common wires. I have two, not sure if everyone does. Common is on every valve so it makes it constant.

4.2 My valve was 6 inches underground and I found it by digging after a beep. My probe would t go down enough because of tree roots.

  1. Mulch beds grow up and out over time. If you know where your valves are do your future self or next homeowner a favor and map it.

  2. Replacing the valve tops are much easier than re-plumbing a valve. Mine were put in with two touching so it sucked but it was possible. I wanted to re-plumb for some dumb reason or just to show I could haha.

  3. Never use a ratchet PVC cutter on installed pipes. It causes cracking.

  4. Make sure you buy the right PVC cement made for irrigation.

Thank you all for you help. It was wonderful to find this community and I have a new respect for irrigation professionals and a greater love my Rachio.
