Step 3 · Connect Drain Hose
Attach one end of a standard garden hose to the drain valve located near the bottom of the water heater tank. The valve will have a threaded, hose-bibb style connection. Ensure the connection is hand-tight to prevent leaks. Place the other end of the hose in a safe drainage area that can withstand hot water, such as a basement floor drain or a bathtub. Make sure the hose end is lower than the bottom of the tank to allow gravity to drain the water effectively.
