Many valves leak because of small debris that gets trapped in the solenoid valve. A thorough cleaning of the interior components solves most leaks.

  1. Turn off the water and electricity
  2. Turn off the electricity to the system as well as the main water valve to the sprinkler system.

  3. Access the valve
  4. Access the valve by opening the lid to the sprinkler system and cleaning out the mud and excess water. Twist and pull out the valve from the box.

  5. Push down the plunger
  6. Push down on the spring-loaded plunger on the solenoid. If it sticks, the solenoid should be replaced. Do not apply any lubricant.

  7. Remove the lid
  8. Unscrew the valve lid and gently remove it, taking care not to drop the spring.

  9. Clean the assembly
  10. Carefully clean the white ports, the diaphragm and seat. Replace the diaphragm if it is cracked. Turn on the water to flush out the pipes before re-installing the valve.

  11. Reassemble the valve
  12. Carefully reassemble the same way it was disassembled. Take care not to strip any screws.
