THERMAL RELIEF VALVES by GENERAL PUMP

Pressure Wash Parts Delivered Verified independent store

The thermal relief valve keeps pressure cleaner pumps operating in a safe range to prevent overheating (caused by recirculating water). At water temperatures above 145º F, packing seals may fail. The pump then overheats. When the system is in bypass mode, the thermal relief valve opens to release hot water. Cold water can then enter the pump so it continues to operate at a safe temperature. Should the pump overheat, thermal relief valves must be replaced.
