Water Heater Relief Valve Discharge Pipe

This pipe is responsible for routing hot water released from the tpr to a proper discharge location.

Water heater relief valve discharge pipe.

These numbers will be printed right on the valve or on a tag attached to the. An air gap eliminates the possibility of backflow from the drain into the discharge piping. This is a very simple video on how to replace add a discharge pipe on a water heater. The valve should be connected to a discharge pipe also called a drain line that runs down the length of the water heater tank.

Not be smaller than the diameter of the outlet of the valve served and shall discharge full size to the air gap. How doers get more done. 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. The discharge piping serving a pressure relief valve temperature relief valve or combination valve shall.

Not be directly connected to the drainage system. This temperature pressure relief valve is not directly attach with the hot water pressure heater. Building codes require temperature pressure relief tpr valves with discharge pipes on all new water heater installations. In most of the disasters caused by hot water heater pipe leaking from the top the trp valve is involved.

Verify the proper valve is installed the tprv on a water heater is set to discharge at 150 psi or 210 fahrenheit. Yes part of the video i have the camera between my teeth lol you ca. You may have an issues with the hot water coming out of overflow pipe. Discharge through an air gap located in the same room as the water heater.

Scalding water and steam escape the tank through the valve and tube to relieve the pressure. Just image the power that can be generated when the water starts to boil inside the tank.

This is to prevent a potentially catastrophic failure.

The purpose of this drain line is to discharge potentially hot scalding water to a safe location so that a bystander is not scalded. If the pressure in the tank exceeds 150 psi or the temperature exceeds 210 degrees fahrenheit the tpr valve opens to release the pressure. Instead it is attached with a discharge pipe link with hot water heater.
