TROUBLESHOOTING:

This troubleshooting table is intended as a helpful guide and is not all inclusive. There could be other causes and solu-

tions for a non-functioning product.

FAULT / SYMPTOM CAUSE POSSIBLE SOLUTION

1. The desired mixed water temperature

cannot be obtained or valve is diffi-

cult to set.

• Inlet temperatures are not within spec-

ification limits.

• Hot and cold supplies are reversed.

• Strainers are blocked.

• Ensure inlet temperatures are within

the specified limits for the valve.

• Refit the valve with Hot/Cold supplies

fitted to the correct connections.

• Clean strainers.

2. Mix temperature unstable or chang-

ing over time.

• Strainers are blocked.

• Fluctuating supply pressures.

• Clean strainers.

• Install pressure regulating valves on

both hot and cold supplies.

3. Either full hot or full cold water flow-

ing from outlet fixture.

• Valve is incorrectly set.

• Hot and cold supplies are reversed.

• Hot/Cold water has migrated to other

inlet.

• Refer also to point 1.

• Adjust mix temperature as required.

• Refit the valve with Hot/Cold supplies

fitted to the correct connections.

• Verify the check valve is not fouled.

Clean if necessary.

4. No flow from the valve outlet.

• Hot or cold water supply failure.

• Strainers are blocked.

• Restore inlet supplies and check mix

temperature.

• Clean strainers.

5. Flow rate reduced or fluctuating.

• Strainers are blocked.

• Fluctuating supply pressures.

• Clean strainers.

• Install pressure regulating valves.

6. Mixed water temperature does not

change when temperature adjuster is

altered.

• Hot and cold supplies are reversed. • Refit the valve with Hot/Cold supplies

fitted to the correct connections.

7. Hot water flows into the cold water

system or vice versa.

• Check valves fouled. • Clean check valves, ensuring debris is

removed.

8. Valve is noisy.

• Excessive water velocity.

• Valve sized incorrectly.

• Reduce water velocity (best achieved

by fitting a pressure regulating valve).

• Check valve specifications and ensure

the appropriate valve is used for

required flow.
