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. 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 25)
6. Rheem Plus models: Service the tempering valve. (Refer to page 32)
