Question
Hello Jim....Maybe an RC 7bi. The unit is only working in one zone.If I do a manual run through the zones the large wheel will turn and complete the turn as expected, but only the zone already watering will water.Cycle through all zones manually and nothing changes. Watering of that zone mentioned continues.If I go to the "REST" position watering still continues.I then have to manually turn off main valve. Lawn is dying.Please help.
Thank you,
Bob

Answer
Hey bob, the problem is in the valve that is turning on. It is stuck on and either needs to be rebuilt or replaced. With this valve stuck on, the other zones don't have enough pressure to work properly. The problem with the valve is either a faulty diaphram or a faulty solenoid. Go to www.irrigationtutorials.com and this website will show you how to properly rebuild the valve. Good luck and have a great day.
