RICE – TXLESOP: MODULE 8 – Water Heater Relief Valve Installation

Water Heater Relief Valve Installation

The relief valve temperature sensor measures temperature and pressure. The relief valve temperature sensor should be located in the hottest part of the tank, typically the top 6 inches. The sensing element should be immersed in the hottest water (at the top 6 inches of the tank).

Usually a dripping relief valve is the result of thermal expansion or foreign material at the seat preventing it to close. A valve that relieves in volume is usually due to excessive high temperature. A new temperature and pressure relief valve should be installed when a water heater is replaced. Alterations of parts may result in devastating damage or injuries.
