Solenoid failure: If the solenoid is not seating properly, water may leak.

  1. Remove the solenoid and check the solenoid for dirt or debris. There should be no dirt or rust on the inside of the solenoid rod/chamber or on the armature. Clean with water if necessary or replace the solenoid
  2. Clean the holes at the flat base of the solenoid port. Use a paper clip or similar tool to clean debris build up inside the 2 holes passing into the top of the actuator
  3. Ensure the solenoid o-ring is in good condition. Replace the o-ring if broken or damaged.

Damaged Diaphragm: If the diaphragm has lost elasticity or if there are cracks or pin holes, it will cause water to leak into your sprinklers.

  1. Replace the diaphragm and other components using the corresponding repair kit.
  2. Clean the actuator and metering rod using water or an emery cloth

Water Pressure

  1. Check for obvious leaks on the actuator. It should be dry under normal use. Replace O-rings and other parts to stop leaks. Tighten screws if leaks occur between top and bottom brass bodies of actuator.
  2. Check your water pressure. Champion actuators are rated to a maximum of 125 PSI, but the optimal range is 80 - 100 PSI for best performance and water conservation. Pressure above 100 PSI may cause performance problems or abnormal wear on the valve.
