Most pumps are protected by a thermal al e. The thermal valve releases water if a
pump starts to run too hot. It will prevent catastrophic heat failure. However, the pump
may have suffered damage and need maintenance, repair, or replacement. If it does
not reset and continues to leak water, the thermal valve may need to be replaced.
