- Turn Off The Heat: Whether the tank is gas or electric, turn off its heating source the night before. If that is too inconvenient, do it at least 30 minutes prior to working on the water heater.
- Check All Valves: Before you begin, inspect all of the valves. Don't miss the temperature and pressure valves. Lift the lever slightly, and you should hear the sound of water running into the drain tube.
- Check For Leaks: Use a solution of dish soap and warm water. Apply it generously to all joints and pipes while watching for bubbles to appear.
- Drain Your Water Heater: Close the incoming-water valve, connect a hose to the drain valve and run the water out. Don't forget to open a hot water faucet inside the house to allow air in.
- Remove Any Buildup: Once all of the water is out, locate the clean-hole and use a flashlight to look inside. Look for soot, rust or sediment. If you do, use hot water to clean the tank or contact Valley Heating so they can advise you on properly cleaning the glass lining without damaging it.
- Refill The Tank: Close all the valves and turn the incoming water back on. Allow the tank to refill and then repeat Step 2 above to ensure your system is working properly.
- Turn Down The Temperature: A small decrease in the highest temperature will decrease your energy use and prolong the life of your water heater.
