TROUBLESHOOTING
FAULT/
SYMPTOM
CAUSE
RECTIFICATION
Either full
hot or cold
flowing from
outlet fixture
• Valve is incorrectly set.
• Hot/Cold water has
migrated to other inlet.
• Refer also to fault/symptom
1 & 2
• Adjust mix temperature
between 35 - 48°C as
required.
• Replace faulty non-return
valves
No flow from
the valve
outlet
• Hot or cold water failure.
• Strainers are fouled
•
Valve functioning correctly.
Restore inlet supplies and
check mix temperature.
• Clean strainers.
Flow rate
reduced or
fluctuating
•
Valve or inlet fittings fouled
by debris.
• Dynamic inlet
pressures are not within
recommended limits.
• Check valve and inlet
fittings for blockages.
•
Ensure operating conditions
are within specified limits
and the dynamic inlet
pressures are nominally
balanced to /- 10%.
Mixed water
temperature
too hot or
cold
• Valve has been tampered
with
• Valve incorrectly set
• Inlet temperatures are not
within specified limits
• Readjust valve to required
set temperature.
• Readjust valve to required
set temperature.
• Ensure inlet temperatures
are within the specified limits
as listed on page 7.
Mixed water
temperature
not changing
when the
temperature
adjuster is
altered
•
Return spring is missing
• Thermostatic element has
failed
•
Install return spring
• Replace thermostatic
element
Mixed water
temperature
adjuster
difficult to
move
• Adjuster at maximum mix
temperature stop.
• Valve piston into overstroke
• Mixed water is at maximum
temperature. No higher mix
temperature adjustment is
available
• Wind adjuster out until set
temperature required is
achieved
Hot water
flows into the
cold water
system or
vice versa.
• Non-return valve has failed • Replace non-return valves
Valve is noisy • Water velocity above
velocity requirements of
AS3500.1 Sec 3.4
• Reduce water velocity.
