lets see if I can focus the ADD long enough to get some help. I ran out of time on Friday and will be going back this week. -I'm in the process of getting a hotel up and running. A cement repair hit a 2'' main. The 2'' repair got crap into just about every valve in the system. All valves that were stuck on are now fixed. -2 zones (four valves) aren't coming on by the timer. The four valves are all in a certain area (after the main repair). -I just recently bought a station master and have been doing troubleshooting with both my volt meter (where I have confidence) and station master to see if I can confidently do my trouble shooting with that. -Clock (ICC): correct voltage with meter and checks out with station master. Ohms are high. I forget right now how high. 150+? I know it's two zones with RB 150PGA valves I believe (RB 1.5'') I believe the station master said good when I tried it at the clock. -valve box: Valve checks out ok by ohms (40 I believe). Turns on and off by station master just fine. Getting 26 volts to the valve by meter. When I check volts in the box by the station master another random unrelated zone pops up. I'm guessing they hit the wire when they were digging around the main. What do you think? I don't have a fault locator. What do they rent for? anything I missed?
