This valve allows water or steam to escape from the water heater if the temperature or pressure gets. Building codes require temperature pressure relief tpr valves with discharge pipes on all new water heater installations. Most residential water heaters have a 3 4 threaded opening for the discharge pipe. 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 relief valve on your water heater has a pipe attached. When no water exits the discharge pipe from the t p valve close the drain valve and remove the garden hose. 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. Place a bucket under the discharge pipe connected to the valve to collect any water and open the t p valve.
