Metering Air Valve Troubleshooting
Problem: Water is dripping from the showerhead.
Cause: Debris on valve seat or orifices.
Solution: Clean and inspect the valve seat.
1. Remove screws and disassemble metering valve, leaving the
plastic upper body firmly snapped together.
2. Clean the valve seat and inspect for deep gouges or scratches.
Replace if necessary.
3. Remove all debris that may be clogging center hole of plastic
diaphragm assembly.
4. Remove any debris clogging the off-center hole in the rubber
diaphragm.
Problem: Valve will not shut off.
Cause: Timing mechanism is clogged.
Solution: Clean timing mechanism:
1. Remove the entire timer assembly from the valve body. If the valve shuts off immediately, the
problem is in the timer assembly. If the valve does not shut off immediately, the problem is due
to debris in the valve seat or orifice.
2. If compressed air is available, blow water and debris from perforated metal sleeve of timing
mechanism.
3. Reinstall the timer assembly into the valve body.
4. Turn the adjusting screw in all the way but do not force screw.
5. Turn adjusting screw out to desired cycle time.
Cause: There is an air leak
Solution: Check assembly:
1. Check all tubing and fittings for proper assembly.
2. Tighten all screws which hold valve together.
Problem: Timing can not be adjusted for more than5seconds.
Cause: There is an air leak
Solution: Check assembly:
1. Check all tubing and fittings for proper
assembly.
2. Tighten all screws which hold valve together.
