3-Attach Hose to Drain Valve
Near the bottom of the tank, locate the tank drain valve and attach a standard garden hose to the drain valve. Be aware that some models may have a cover over the valve opening. Place the other end of the hose in a floor drain or on a driveway where it can drain safely. If necessary, buckets can be used, but be careful not to be burned by the hot water as you work.

4-Open Hot Water Tap
Open a hot water tap nearest to the water heater, preferably on the floor above. This alleviates pressure in the system, allowing the water to drain quickly from the tank, much like removing your finger from the top of a drinking straw filled with liquid.

5-Open Drain Valve
Open the drain valve and allow the water to drain from the tank. Again, the water will be hot, so use caution. Once all water has drained from the tank, briefly turn the cold water supply on to the tank. This will stir up any remaining sediment. Repeat this process until the water runs clear. Dave Moody has seen some severe cases of sediment build up and says this: “In some cases, sediment may block the opening of the drain valve, limiting the flow of water. If this happens it’s best to call in an expert for assistance.”

6-Close Drain Valve, Refill Tank, Turn Water Heater Back On
Close the drain valve, remove the hose, and turn on the cold water supply. The tank will begin to fill. Go back to the hot water tap opened earlier. Once cold water begins to flow from the tap, turn it off. Turn the gas valve back on from the pilot position or turn electricity back on to the tank. Be sure to check the valve opening once it’s closed to ensure there are no water leaks.
