Closed System Thermal Expansion:
Periodic discharge of the T/P relief valve or failure of the element gasket may be due to thermal
expansion in a closed water supply system. The water utility supply meter may contain a check valve,
back flow preventer or water pressure reducing valve which will create a closed water system. During
the heating cycle of the water heater, the heated water expands causing pressure inside the water
heater to increase. The T/P relief valve may discharge hot water under these conditions which results in
a loss of energy and a build up of lime on the relief valve seat.
To prevent this from happening, there are two recommendations:
1. Install a diaphragm-type domestic hot water expansion tank (suitable for potable water) on
the cold water supply line. The expansion tank must have a minimum capacity of 1.5 U.S.
gallons for every 50 gallons of stored water.
2. Install a 125 PSI pressure relief valve in the cold water supply line. Make sure the
discharge of this valve is directed to an open drain and protected from freezing. Contact
your local water utility or plumbing inspector for information on how to control this situation.
Never plug the outlet of the relief valve.
Filling the Water Heater
Caution!
Before plugging the water heater electric cord into an outlet, be sure that the system is
completely charged with water and All AIR IS REMOVED. Before connecting the power, fill the tank and
system with water and check for leaks. To be sure that all air is out of the water system, open the hot
water faucets on your fixtures until constant water flows from them. Otherwise any air remaining in the
tank will cause the water heater element to self destruct.
Procedure:
1. Open the hot water faucet.
2. Open the cold water supply valve.
3. When continuous water flows out of the faucet, the tank is filled.
4. Close the hot water faucet.
5. Check entire system for leaks.
