Troubleshooting Guide

Start Up Conditions

THERMAL EXPANSION

Water sup,ply 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

problems. When these devices are not equipped with an internal oy-pass, and no other measures are taken, the devices cause the

water system to be dosed. 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 rea_ed, 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 dosed 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 su_.plier 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 inlet water pressure is higher than 40 psi, the expansion tank's air pressure must be adjusted to match that pressure, but must not be higher than 80 psi.
