Further Information


Draining a water heater regularly is the best way to extend its life and ensure efficiency. Begin by turning off the power or pilot light. Turn off the valve supplying water to the top of unit, and connect a garden hose to the drain spigot at the bottom. Once you open the drain, you’ll need to flip the pressure relief valve on the top or side of the heater to release the vacuum so the water will drain. Once the draining water has removed the sediment in the tank, you can close the drain, turn back on the water, and restore the power.
