Hot Water Tank Pressure Relief Valve Drain Pipe

All of our reece store offer a range of valves to help regulate manage stop and direct flow of any water supply.

Hot water tank pressure relief valve drain pipe. Our dura arco and rmc ball valves are made for both water and gas applications to assist in opening and closing the distribution of flow. 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. So this release of its pressure causes your hot water tank overflow pipe dripping towards the floor where the hot water heater is placed. 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.

Temperature pressure relief valve discharge tubes drain lines their piping. This pipe is responsible for routing hot water released from the tpr to a proper discharge location. The valve should be connected to a discharge pipe also called a drain line that runs down the length of the water heater tank. 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.

It s designed to release the pressure when there is too much of a load built up inside the water heater. 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.
