Water Heater Pressure Relief Valve Discharge Pipe

Local building codes vary but most require a catch pan under the water heater with a discharge pipe that ends above the rim of the pan to.

Water heater pressure relief valve discharge pipe.

A typical water heater has a safety device known as a relief valve and is sometimes known as a temperature and pressure valve. Water heater pressure relief valve hot water recirculating pump white water heater accessories rheem water heater accessories rheem 50 gal parts rheem gas igniter. Verify the proper valve is installed the tprv on a water heater is set to discharge at 150 psi or 210 fahrenheit. In most of the disasters caused by hot water heater pipe leaking from the top the trp valve is involved.

Scalding water and steam escape the tank through the valve and tube to relieve the pressure. The discharge piping serving a pressure relief valve temperature relief valve or combination valve shall. This prevents an explosion. Attached to the relief valve is a discharge pipe.

This temperature pressure relief valve is not directly attach with the hot water pressure 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. You may have an issues with the hot water coming out of overflow pipe. A trapped tpr dischage pipe is a common defect when a replacement water heater s tpr valve is lower than the original one and the installer connects to the exisitng discharge piping at the wall.

This pipe is responsible for routing hot water released from the tpr to a proper discharge location. Not be smaller than the diameter of the outlet of the valve served and shall discharge full size to the air gap. If pressure builds or temperatures reach dangerous levels the valve opens up and discharges the pressure. Building codes require temperature pressure relief tpr valves with discharge pipes on all new water heater installations.

8 termination of the tpr drain pipe cannot be more than 6 inches or less than two pipe diameters above the floor ground or waster receptor flood rim level. This temperature pressure relief valve is attached to the discharge pipe. So this release of its pressure causes your hot water tank overflow pipe dripping towards the floor where the hot water heater is placed. Not be directly connected to the drainage system.

Instead it is attached with a discharge pipe link with hot water heater. It s designed to release the pressure when there is too much of a load built up inside the water heater. How doers get more done.
