Water Heater Pressure Relief Valve Pipe Outside

The valve should be connected to a discharge pipe also called a drain line that runs down the length of the water heater tank.

Water heater pressure relief valve pipe outside.

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 temperature in the water heater reaches 210 or the pressure reaches 150 psi the relief valve will open reducing the pressure or releasing heated water to be replaced with cold water. Water heaters come equipped with a temperature and pressure relief valve also known as a tprv. 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.

If at any point the temperature or pressure reaches an unsafe level the water heater triggers the relief valve to open and release water out of the tank until the temperature. When no water exits the discharge pipe from the t p valve close the drain valve and remove the garden hose. It s designed to release the pressure when there is too much of a load built up inside the water heater. Many regions require the t p valve to lead outside for added safety and some may even require two valves for redundancy.

This temperature pressure relief valve is attached to the discharge pipe. T p valve the temperature and pressure relief valve is an important safety device which goes off when your tank exceeds 210 degrees fahrenheit or 150 psi. Then turn it off so that the cold water couldn t enter in the system. This is to prevent a potentially catastrophic failure.

In order to replace the temperature pressure relief valve of hot water heater simply follow these steps. 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. The relief valve is an important safety feature on the water heater. What does the relief valve do.

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. Just image the power that can be generated when the water starts to boil inside the tank. Place a bucket under the discharge pipe connected to the valve to collect any water and open the t p valve. 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 your system is on gas turn off the gas supply. Open the drain valve on the water heater then open the hot water tap at a nearby sink to release the vacuum on the tank. A good solution to this risk is the relief valve. This valve allows water or steam to escape from the water heater if the temperature or pressure gets.
