solar water heater T/P valves

The explosion of a tank type water heater can be caused by a malfunction which causes the heater to continue to heat even though the set point of the thermostat has been reached. Water heaters are designed to operate safely with a (T&P) valve to automatically release excessive pressure to prevent an explosion. Manufacturers instructions suggest at least an annual testing of this T&P valve to be sure it would function if such a malfunction were to occur. When was the last time you tested yours? (Note: Home inspectors do not test these valves because they often fail during the test requiring replacement.) In some hard-water areas, as many as one out of every four T&P valves fail this annual test. Such water heaters are a disaster awaiting only the malfunction of a thermostat to explode with devesting fury.

Water heaters are one of the most beneficial component of our homes providing hot water for baths, washing of clothes and dishes for their lifetime if properly cared for. If not cared for they can explode with destructive force comparable to the chaos we see on television caused by suicide bombers in some parts of the world. Why is it that you are concerned about the suicide bomber but pay no attention to the potential for such occurrence in your own home. Any home owner who fails to maintain the T&P valve properly may unknowingly and unwittingly become a suicide bomber in his or her own residence.
