Never installed a sprinkler system but bought a 25 year old house with 15 automatic valves all RICHDEL. I did replace a rubber diaphram once years ago and a couple of solonoids over the years just simple stuff but now i have more difficult issues and not sure what to do. First off there is no water shut off valve at the valve head manifold in the rear of the house, so i have to go out to the curb in front and use the 2 foot main water valve handle shutting off all the water to the house in order...
