Check for crossed water
connection. Replace the
T&PR valve
Remove the extension fitting
and repair leak using teflon
thread tape
Leak is probably condensate
formed in the combustion
chamber during the heating
cycle. Large quantities of
condensate can be produced
during cold weather or after
large draw offs. May also be
evident on initial lighting.
Normal operation
Replace the T&PR valve with
one of the correct rating.
Do not use reconditioned
T&PR valves
Is
the water leak
intermittent?
Is
the T&PR
valve continuously
discharging
water?
YES
WARNING: Water under pressure and at
temperatures up to 70 degrees may be present.
Isolate water supply to water heater and relieve
pressure through a hot tap prior to removing fittings
Existing pressure limiting valve
faulty - replace.
Fit a pressure limiting valve if
not already fitted.
Replace T&PR valve if
required
Is
the inlet
extension fitting
leaking?
Is
the T&PR valve
extension fitting
leaking?
NO
Is
the anode/s
leaking?
Is
the gas
control sheath
leaking?
NO
YES
NO
The continuous addition of cold
water will cause excessive condensate
to be produced and will also cause
increased energy costs
YES
Is
the outlet
extension fitting
leaking?
NO
NO
NO
Is
the water supply
pressure above
1120kPa?
Is
the correct
T&PR valve
fitted?
YES
NO
Is the
water temperature
above 85 degrees
Celsius?
NO
NO
YES
