Discharges water to prevent cylinder damage from excess high temperature or pressure

Reliance Valves TPR28 Pressure & Temperature Relief Valves are high-capacity pressure and temperature relief valves. The valve protects against over pressurisation or extreme temperatures over 95°C, which can occur within an unvented hot water system if the input temperature or pressure controls fail.

The valves are designed to be installed directly to the upper portions of a hot water cylinder, as this is where the hottest temperature is found. If the valve is opened, it will lift off its seat and release the water to the waste, reducing the pressure or temperature within the cylinder.
