Guys quick question. Got a new client (I mainly do maintenance mowing etc) and was doing an audit on there system last Fri. There seems to be a zone that runs constantly. Obviously this is keeping the rest of the zones from working do to the pressure loss from the zone that wont shut off. I am assuming the valve has gone bad in regards to the zone in question. Would you say that is a fair assumption. I will be locating the valves after the forth and have done little investigating on the system to this point. The thing that seems strange is that the zone that is running all the time never fully pressurized. Now I didn't go through all the zones so maybe I never got to this one. It's hard to tell cause it's a very large property and there could have been another zone trying to run besides the ones I did see. Anyway any in put would be appreciated. I'd like to have a little idea of what to look for before Mon when I head out to locate the valves.
