A water heater is a vital appliance in any home, providing hot water for various uses. Over time, sediment and minerals can build up inside the water heater, reducing its efficiency and potentially causing damage. Regularly flushing your water heater can help prolong its life and improve its performance. Here are 13 steps to help you flush your water heater.
1. Turn off the power: If you have an electric water heater, shut off the power at the breaker box. For gas water heaters, turn off the gas by turning the control valve to the “off” position.
2. Turn off the cold-water supply: Locate the cold-water supply valve near the top of your water heater and turn it off.
3. Attach a hose: Connect a garden hose to the drain valve located at the bottom of your water heater.
4. Choose a draining location: Keep in mind that hot water can damage delicate plants or grass. Position the other end of the hose where you want to drain the hot water, preferably in a safe area away from any plants or grass.
5. Open a hot water tap: This will release any pressure within your plumbing system, facilitating the draining process.
6. Open the drain valve: Slowly open the drain valve and allow the hot water to flow through the garden hose.
7. Let it drain completely: Allow all of the hot water to flow out of your water heater before proceeding with the next step.
8. Turn on cold-water supply: Once your hot water tank is empty, turn on the cold-water valve to flush out any remaining sediment or build-up inside your tank.
9. Check for clear discharge: Monitor the color of water coming out through your garden hose – when it runs clear, you can move on to step 10.
10. Close drain valve and remove garden hose: After ensuring that sediment has been properly flushed from your water heater, close the drain valve and remove the garden hose.
11. Fill the tank: With the drain valve closed, turn on the cold-water supply. Wait for the water pressure to equalize before opening a hot water tap inside your home to release trapped air.
12. Turn power back on: Once your water tank is full, turn on the power supply. For electric units, turn on the breaker at the breaker box. For gas units, relight the pilot or turn on the gas supply valve.
13. Check for leaks: Inspect your water heater’s drain valve and supply lines for any signs of leaks.
By following these 13 steps, you can successfully flush your water heater and maintain its efficiency and longevity. Regular maintenance is essential to keeping your water heater in top shape, ensuring that you always have access to hot water when you need it.
