water heater temperature and pressure release valve

QUICK ANSWER: The temperature and pressure release valve is a critical part of your water heater and your plumbing system. It prevents your water heater from exploding or causing a flood in your home.

DETAILS: The T&P valve is connected to your water heater but can be installed anywhere in your home’s plumbing system. It should always operate properly to insure that your water heater doesn’t explode or cause a flood. The valve is designed to drain water if it senses the pressure is too high or the temperature is too high. The valve can easily malfunction and should be tested to make sure it is operating properly.
