1 Turn off the water heater’s gas valve or electrical power, relying on whether it is a gasoline or electric powered heater.
2 Turn off the water inlet valve that controls the provide of water to the tank. Be positive this is the incoming bloodless water valve, not a valve for the outbound hot water (the pipe should be cold).
3 Attach a hose to the drain valve at the backside of the water heater, and run the hose to a drain, to the outdoors, or to a giant bucket. Make certain the stop of the hose is beneath the degree of the drain valve.
4 Open a hot water faucet somewhere in the residence or the water heater’s pressure-release valve to let in air so the water heater can drain.
5 Open the water heater’s drain valve. If you’re just flushing sediment, enable three or four gallons to exit until the water from the drain valve runs clear. Again, beware of warm water needs.
