Step 3 · Connect Hose and Open Faucet

Attach a standard garden hose to the drain valve located at the bottom of the water heater tank. Make sure the connection is secure to prevent leaks. Run the other end of the hose to a suitable drainage point, such as a floor drain, a large utility sink, or outside to a driveway. After the hose is in place, go to a sink inside the house (preferably on an upper floor) and open the hot water tap fully. This will allow air into the tank, breaking the vacuum and allowing water to drain out smoothly.
