Hot Water Heater Relief Valve Pipe

Place a bucket under the discharge pipe connected to the valve to collect any water and open the t p valve.

Hot water heater relief valve pipe.

The relief valve on your water heater has a pipe attached. The tpr valve will activate if either water temperature measured in degrees fahrenheit or pressure measured in pounds per square inch psi exceed safe levels. 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. You may have an issues with the hot water coming out of overflow pipe.

Water heaters come equipped with a temperature and pressure relief valve also known as a tprv. Instead it is attached with a discharge pipe link with hot water heater. The pipe itself needs to be either copper cpvc or galvanized water piping. When no water exits the discharge pipe from the t p valve close the drain valve and remove the garden hose.

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 for the reason. The valve should be connected to a discharge pipe also called a drain line that runs down the length of the water heater tank. In most of the disasters caused by hot water heater pipe leaking from the top the trp valve is involved. This valve allows water or steam to escape from the water heater if the temperature or pressure gets.

Most residential water heaters have a 3 4 threaded opening for the discharge pipe.
