Actuator Repair Kits
Identify Brand & Date of Manufacture
Start by double checking that you have a Champion brand actuator. All Champion actuators will have “CHAMPION” stamped on the top of the actuator, as in the image below. If the actuator has a different brand stamped on it, please refer to that manufacturers repair information. Next, identify the manufacturing date of the actuator. If the original documentation is unavailable, you can locate the original manufacturing date on the actuator. The date stamp is located between two of the screws around the top or along the side of the hexagon neck above the threads (see images below).
The date stamp should read as follows:
Date code between two screws (i.e. 04/02)
Date code on hexagon neck (i.e. 06/16)
i.e 06/16
If your date code is located like above: · Category 1- Date codes older than 2014, skip to page 4 · Category 2- Date codes from or after 2014, skip to page 5
If your date code is located on the neck, like above,: · Catagory 3- Skip to page 6

Troubleshooting Guide
Common Problems and Solutions
#1: Valve has continuous slow leak or will not fully shut off/close · 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.
· Damaged or worn seat washer or metering screw:
1. Test by opening manual bleed screw. If no water leaks from the bleed screw, it’s likely caused by debris or build up at the washer, the metering screw, or the metering rod inside.
2. Remove actuator from valve and check the seat washer. If washer is pitted, damaged or overly worn, flip the washer over or replace it.
3. Clean the valve seat of any debris. If there are any blemishes or nicks on the valve seat, you can gently polish it with 400-600 grit wet/dry sandpaper.
4. For actuator models before 2014, if the center hole of the meter screw has become enlarged, replace the screw with components from the corresponding repair kit.
· 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.
#2: Valve will not open, or only opens part way, when energized
· Solenoid failure or is not receiving power:
1. With the controller/timer activated to the valve, place your fingers on the outside of the solenoid.
2. If a slight vibration is felt, the solenoid is receiving power and is not the cause. Ensure the solenoid is not screwed too deeply into the seat and that the O-ring is not damaged.
3. If the solenoid does not vibrate or hum when activated, use a volt meter to ensure 24 volts (+/- 2 volts) are present out of the controller as well as at the solenoid. If the controller output is sufficient (24 VAC) but the solenoid does not vibrate or hum, check the wiring using the volt meter at the solenoid
· Damaged diaphragm or brass diaphragm shaft:
1. Disassemble the actuator and check the diaphragm for damage. If the diaphragm is damaged, replace the diaphragm and assembly parts.
2. Check the brass shaft below the diaphragm for damage or enlarged opening. If the shaft is damaged, replace the actuator
Troubleshooting Guide
Common Problems and Solutions
#3: The valve does not shut off automatically · Controller malfunction or clogged /damaged actuator.
1. Check the controller to see if it is sending power to the station.
2. If the valve is not getting power from the controller and valve continues to run, try tapping the actuator with a rubber mallet. If the actuator closes after tapping it, the actuator may need a through cleaning to prevent it from sticking. You may want to disassemble and replace the seat washer, meter screw, solenoid and other parts.
3. If the valve does not turn off after tapping it, ensure the bleed screw is tightened down and the O-ring is intact. Clean out the solenoid ports to ensure it is not stuck open, and check the diaphragm for ruptures, pin-holes or tears.
#4: Water leaks out of the actuator
· Worn O-rings
1. Check the O-ring on the bleed screw and solenoid. Ensure the bleed screw threads are not stripped. Replace bleed screw, solenoid and O-rings as needed.
2. Disassemble the actuator and check the O-ring on the flow control stem. Replace as needed and apply silicone grease to the O-ring before reassembling.
· Leaks between top & bottom of actuator sections
1. Disassemble and check the diaphragm. Clean the actuator and replace parts as needed.
2. Re-assemble the actuator, ensuring the screws are tightened evenly in a cross-pattern order.
3. If water still leaks between top & bottom sections, place vise grips between two screws and squeeze the sections together while tightening the screws. Repeat the process between all other screws.
· Water leaks from where the actuator threads into the valve body
1. Check and replace the red fiber gasket
#5: Loud buzzing from the valve
· Wiring size may be too small to allow enough voltage to turn the actuator on.
1. Determine if the timer is the problem by switching the wires at the timer. For example, if the valve at station 1 buzzes, but station 2 does not, swap the wires for stations 1 & 2 at the controller. If the buzzing at station 1 stops and now station 2 buzzes, the timer is not functioning normally.
2. If the buzzing continues with station 1, check the solenoid and replace as needed.
#6: Constant leaks out of the anti-siphon valve
· Worn out float, washer or gasket 1. Remove the anti-siphon cap (12-sided brass cover). Use Calcium/ Lime/Rust remover if the cap is stuck.
2. Pull out all parts and check for damage: red fiber gasket, plastic float & washer.
3. Ensure the brass cap is not damaged, specifically inspect the brass rod in the center to ensure it is clean & straight.
4. Replace the anti-siphon components with the corresponding repair kit. Ensure the plastic float is centered on the brass rod on the cap when reassembled.
· Sprinklers, gravity or other cause:
1. Ensure the anti-siphon valve is above the sprinklers it is supplying. Water will leak out of the anti-siphon valve if sprinklers are up-hill. Antisiphon valve should not be installed under ground.
2. Blockage in the sprinkler supply lines can cause leaks.
