The relief valves are installed on every water heater for your safety. If the tank builds up too much pressure inside it can explode. The relief valve is there to relieve the pressure in the tank. They are set to a certain pressure and when the pressure inside the tank exceeds this limit the pressure valve is activated and will relieve the pressure in the tank.
