SPRINKLER TALK FORUM - You Got Questions, We've Got Answers

Hello friends,

I have a fairly complex system. Everything is built upon Orbit 1" Jar-Top inline valves using Orbit manifolds.

Zones 1 and 2 are drip lines, and the other (at least 12) zones run sprinklers for our lawn.

The problem I am having is that the 2 drip system zones won't turn off. They run 24 hours a day unless I literally turn off the water supply.

I have a carefully prepared map of all zones, so I feel certain I have eliminated the possiblity I am looking at the wrong valves.

I have replaced both valves. I replaced the zone 1 valve last season, and the zone 2 valve today. Nothing seems to help.

If it matters, this system is all installed in my well house. I have a constant-pressure device that was installed last year, along with a new (as of last year) pressure tank. I can provide photos if needed.

Any suggestions?
