These Devices are literally the last line of defense against catastrophic pressure relief valve failure or even lose of life. As is heated, it expands. In this case, the 's expansion is probably being limited by a backflow preventer or a nonbypass pressure regulator on the inlet pipe. This results in a pressure increase that can be reduced in one of two ways--by someone drawing hot from a tap, or by the relief opening on the heater. Stainless steel pressure relief discharges after the hot- demand has passed because the heater's thermostat is still causing the electrical heating elements to be activated or the burner to fire. The heater is producing hot but the hot- faucets are closed, creating a pressure buildup that is relieved by the . The relief discharges after a large amount of is drawn because a small hot- demand will not cause the heater's burner to fire or its element to be activated. Thermostats in residential heaters let the temperature drop 15 to 25 degrees F before activating a burner or heating element. Backflow preventers and nonbypass pressure regulators are that prevent contamination of a municipal supply system. They stop in the house's plumbing from flowing back into the municipal system. The watt and the watt ball have the great role in it. Its working is very accurate.
