THERMAL EXPANSION

Water supply systems may, because of such events as high line pressure, frequent cut-offs, the effects of water hammer among others, have installed devices such as pressure reducing valves, check valves, back flow preventers, etc._to control these types of _roblems. When these devices are not equipped with an internal

y-pass, and no other measures are taken, the devices cause the water system to be closed. As water is heated, it expands (ther-

mal expansion) and closed systems do not allow for the expan- sion of heated water.

The water within the water heater tank expands as it is heated and increases the pressure of the water system. If the relieving point of the water heater's temperature-pressure relief valve is reached, the valve will relieve the excess pressure. The temperature-pressure relief valve is not intended for the constant relief of thermal

expansion. This is an unacceptable condition and must be cor- rected.

It is recommended that any devices installed which could create a closed system have a by-pass and/or the system have an expan- sion tank to relieve the pressure built by thermal expansion.

Thermal expansion tanks are available from Sears stores and

through the Sears Service Centers. Contact the local plumbing inspector, water supplier and/or the Sears Service Center for assistance in controlling these situations.

NOTE: Expansion tanks are pre-charged with a 40 psi air

charge. If the i,nlet water pressure is higher than 40 psi, the

expansion tanks air pressure must be adjusted to match that pressure, but must not be higher than 80 psi.
