I had a zone stop working on Sunday. When I turned it on the first head in the series started sputtering and stopped. The other three zones are functioning normally. I checked the box and there is a small dripping from only this zone so I am assuming that either the solenoid and or the valve itself is bad
I am planning on replacing it with a new valve. I know I need to turn off the water. I believe I have a Stop & Waste valve and need to get a curb key so that I can turn it off. ( it is 6' below ground). Do I need to bleed the valve? do I need to mess with the back flow preventer?
