Preventative Maintenance
It is suggested for peak performance that the water heater be serviced annually.
1. Check for discharge from the T&PR valve. When the element is operating a small
discharge of water may be evident. Direct access to the valve is via the circular plastic
cover at the top of the unit. Operate the valve-easing lever to ensure the valve opens
and resets properly. Always open and close the valve gently. The T&PR valve should
be replaced at 5-yearly intervals.
2. Check for leaks at all tank fittings.
3. Check for signs of excessive corrosion on the water heater jacket.
4. Isolate power to the water heater and check all electrical connections for signs of
overheating due to poor connection.
5. Conduct an insulation test on the water heater. (Refer to page 18)
