Hot Water Tank Pressure Relief Valve Pipe

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

Hot water tank pressure relief valve pipe.

Super hot and high pressure water gets released to keep the tank from exploding like a bomb. If the water inside the unit gets too hot usually above 210 degrees or pressure builds up too high above 150 psi the water heater can become damaged or even explore. If the hot water worked okay and wasn t excessively hot or steam didn t come out when you turned on a faucet the problem is probably with your pressure relief valve. This temperature pressure relief valve is attached to the discharge pipe.

If at any point the temperature or pressure reaches an. Temperature pressure relief valve discharge tubes drain lines their piping. Scalding water and steam escape the tank through the valve and tube to relieve the pressure. The p1000axl 150c pressure relief valve is set at the p1000axl 150c pressure relief valve is set at 150 psi and utilized on water heating storage vessels for protection against over temperature or excessive pressure not for steam service.

If the pressure in the tank exceeds 150 psi or the temperature exceeds 210 degrees fahrenheit the tpr valve opens to release the pressure. Heated water generates pressure. But if one does it s a big deal. Should that pressure go beyond what it considered safe or into the danger zone.

How often should the pressure relief valve on a hot water tank be replaced. Temperature pressure relief tpr valves rarely go off. It s hard to say without actually examining your hot water tank whether the problem lies with the tank itself or the pressure relief valve. The relief valve is an important safety feature on the water heater.

Primarily used on storage tanks p1000axl materials include cast brass or bronze for the main valve body quality stainless steel 300 series internals. This pipe is responsible for routing hot water released from the tpr to a proper discharge location. A pressure relief valve well as the name implies relieves the pressure in your tank. The pressure relief valve is an important safety component of a water heater and a malfunction can have disastrous.

Local building codes vary but most require a catch pan under the water heater with a discharge pipe that ends. It s designed to release the pressure when there is too much of a load built up inside the water heater.
