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 elements are 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 cylinder 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 'Electrical insulation test' on the water heater. (Refer to page 30)
6. Check evaporator fins and fan blade for build up of dust or debris.
7. Check for sludge build up and if necessary drain and flush tank.
