Hot Water Tank Pressure Relief Valve Drain Pipe

Temperature and pressure relief valves shall be installed so that the sensing element of the valve extends into the heater tank and monitors the temperature in the top 6 inches of the heater or tank.

Hot water tank pressure relief valve drain pipe. Temperature pressure relief valve discharge tubes drain lines their piping. The temperature pressure relief valve or tpr valve on any heated appliance that contains water such as a heating boiler hot water tank water heater water cylinder must have a drain line or discharge tube properly installed routed and made of proper materials. The valve should be connected to a discharge pipe also called a drain line that runs down the length of the water heater tank. All of our reece store offer a range of valves to help regulate manage stop and direct flow of any water supply.

This pipe is responsible for routing hot water released from the tpr to a proper discharge location. But if the termination of the piping is not readily visible such as if it is located under the house the water will continue to drain until the homeowner gets an amazing electric or gas bill and goes searching. This temperature pressure relief valve is attached to the discharge pipe. All pressurized non storage type water heaters shall be provided with a pressure relief valve installed at the hot water outlet with no shut off valve between the heater and the relief valve.

If the water heater thermostat fails to turn off at its temperature setting and continues to heat the water indefinitely the tpr valve will open and let the overheated water out. So this release of its pressure causes your hot water tank overflow pipe dripping towards the floor where the hot water heater is placed.
