The temperature and pressure relief valve is a safety feature we need to work on any water heater. Many components work together on a water heater so that our water is at the perfect temperature and comes out with just the right amount of pressure.
The temperature and pressure release valve protect us when any components on the water heater go out. It's important to remember that a pressure valve is made to discharge water from the tank if there are any issues. Figuring out if it’s leaking or not can be confusing.
