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 23).
