Sprinkler Valve will not close
I replaced two solenoids that were rusty with new ones and I cannot now get the sprinkler valves to close. The system I have installed is a Richdel and it would be approximately 17 years old. The solenoids that I purchased are made by Lawn Genie (L10000) and appear to fit okay. I have checked the electric and each solenoid is being energized when the start and stop commands are received from the control box. I also replaced the diaphrams in each of the valves.
I have tried everything to get the valves to close to no avail. Looking for any suggestions especially if I have chosen the incorrect solenoid as a replacement.
