Product Details
Brand: Popular Brands
Part Number: PM005402AV (PM063060SV)


This small but very important valve’s function is to relieve or bleed water when it senses the water temperature in the pump is too high, to prevent the pump from overheating. When the pump is in “bypass” mode, hot water is dumped through the valve and allows cold water to enter the pump, keeping it cool. If the pump does overheat, the thermal relief valve should be replaced.
