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.

Water heaters come equipped with a temperature and pressure relief valve also known as a tprv. If all goes well a tpr valve never gets used except during testing. Primarily used on storage tanks p1000axl materials include cast brass or bronze for the main valve body quality stainless steel 300 series internals. On the side or top of your water heater tank is a valve connected to a metal or plastic discharge tube pointing downward.

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.

Many regions require the t p valve to lead outside for added safety and some may even require two valves for redundancy.

Without the water heater pressure relief valve the pressure within the water tank could become higher than the tank is meant to handle which could result in an explosion.
