9.2.4 Continuous discharge from ECV & PTR valves
Discharges of more than 15 litres of water in 24 hours indicates
that the valve may not be functioning correctly. This may be
remedied by gently easing the valve lever for a few seconds as
described under Routine Service to dislodge any foreign
matter.
CAUTION: Continual flow may also indicate
high water pressure which will require a
pressure limiting valve to be fitted by an
authorised person.

Maintenance and repair

WARNING:
The electric storage water heater should
only be serviced by a qualified person, and in
accordance with the Plumbing Standard AS/
NZS 3500.4 and local authority
requirements.
Routine service will assist in prolonging the
life of your water heater, and help ensure
trouble free operation.

10.1 Periodic Inspection

It is recommended that a periodic inspection of the valves,
thermostat, heating elements and wiring should be made by a
service person qualified in electric appliance repair.
Most electrical appliances, even when new, make some sound
when in operation. If the hissing or singing sound level
increases excessively, the electric heating element may require
cleaning. Contact a qualified installer or service agent.
10.2 Pressure and temperature relief valve (PTR
Valve)
At least every 6 months:
▶ Lift and release the lever handle on the PTR valve, to make
certain the valve operates freely.
Allow several litres to flush through the discharge line to an
open drain.
If the valve does not discharge water when the release lever is
opened, or does not seal properly when closed, replacement
by an authorised person must be arranged immediately. The
PTR valve is not serviceable.
DANGER:
Never replace the PTR Valve with one which
has a higher pressure rating than is specified
for your water heater.
