Each water heater is equipped with a temperature and pressure relief valve, sometimes referred to as a “T & P Valve” or a “pop-off”. These valves are designed to relive any overpressure in the tank in the event of a malfunction. If the T & P valve is leaking, it should be inspected by a trained professional because it may be an indicator of a larger problem. WATER HEATER T & P RELIEF VALVES SHOULD NEVER BE REMOVED AND PLUGGED AS THIS CAN LEAD TO DANGEROUS OVERPRESSURE OF THE WATER HEATER.
