There are two reasons why sprinklers would continue to run with the controller Off or Unplugged:
- It's possible your valves were opened manually. Locate your valve box(es) and turn the solenoid(s) clockwise until snug. The solenoid is located on top of the valve and looks like a cylinder with two wires protruding out of it.
- It's also possible that debris in the valve is causing the diaphragm to remain open.
To fix this problem:
- Disassemble the valve.
- Rinse all parts with clean water.
- Reassemble the valve.
If you cannot locate your valves, contact the contractor who installed the system.
