Draining a hot water heater is essential for removing sediment buildup and maintaining its efficiency. Here's how you can drain a hot water heater:
1. **Turn Off the Power**: For electric water heaters, turn off the power at the breaker box. For gas water heaters, set the gas control valve to the "pilot" position.
2. **Allow the Water to Cool**: Let the water in the tank cool down for a few hours. Hot water can cause burns, so it's essential to wait until it's safe to handle.
3. **Locate the Drain Valve**: The drain valve is typically located near the bottom of the water heater. It looks like a spigot or hose bib and may have a handle or knob.
4. **Connect a Hose**: Attach a garden hose to the drain valve. Make sure the hose is long enough to reach a floor drain or an area where the water can safely drain without causing damage.
5. **Open a Hot Water Faucet**: To allow air into the tank and help with drainage, open a hot water faucet somewhere in your home.
6. **Open the Drain Valve**: Carefully open the drain valve by turning the handle counterclockwise. Be prepared for hot water and sediment to start flowing out of the hose.
7. **Drain the Tank**: Let the water drain completely from the tank. You may need to open the pressure relief valve or remove the hot water supply line to help with drainage.
8. **Flush the Tank (Optional)**: If you're removing sediment buildup, you can flush the tank by turning on the cold water supply briefly while the drain valve is open. This will help loosen and remove sediment from the bottom of the tank.
9. **Close the Drain Valve**: Once the tank is drained and flushed, close the drain valve by turning the handle clockwise.
10. **Refill the Tank**: Turn the cold water supply back on to refill the tank. Keep the hot water faucet open until water starts flowing steadily from it, indicating that the tank is full.
11. **Turn the Power Back On**: For electric water heaters, turn the power back on at the breaker box. For gas water heaters, set the gas control valve to the desired temperature.
12. **Check for Leaks**: Inspect the drain valve and connections for any leaks. Tighten fittings if necessary.
