Question

What causes a water heaters relief valve to discharge water?

Comments

^{A water heater relief valve discharges water when the temperature of the water in the tank reaches a certain level.}

Answer 1

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.

Answer 2

The pressure relief valve on a water heater may discharge water due to excessive pressure buildup or overheating within the tank. This can be caused by a faulty valve or thermostat, high water temperature or pressure, or a buildup of sediment in the tank.

Answer 3

A water heater's relief valve is designed to open and release pressure and excess heat if the water heater's temperature or pressure becomes too high. This is a safety measure to protect the water heater from damage.

Answer 4

A water heaters relief valve will typically release water when the valve is placed in the "off" position. This water will flow out of the heater and into the air conditioning unit and then finally into the water. This water is heat from the water heater and, as a result, will cause the water heater to work harder to keep the temperature within a set range.

Answer 5

If at any point the temperature or pressure reaches an unsafe level, the water heater triggers the relief valve to open and release water out of the tank until the temperature and pressure return to normal.
