Plumber Tips for Flushing Your Water Heater

In order for your plumbing system to function at its best, it is important to keep it clean. Flushing your water heater is really simple, however it is effective and will extend its life and help it operate at maximum efficiency.

Over time, sediment builds up in your water heater, and it can block the drain, causing it to stop working efficiently. If you live in an area with hard water, accumulation will be worse. When minerals such as calcium, magnesium and iron build up at the bottom of your water heater, your water will become discolored and can cause your hot water taps to become rusty. It can clog your fittings and cause spurting, sputtering, and even restriction to your water flow.

When gas water heaters with burners at the bottom start accumulating deposit, that sediment starts acting as an insulation blanket that cuts down the efficiency of the burner. This causes increased energy costs and can cause the tank to fail. When the sediment is stirred up with the incoming water, and it is carried to the faucet aerators, washing machine filters and showerheads, it can clog the fittings.

When your hot water system is not functioning at full efficiency, or if you notice dirty water, restricted water flow or splattering and stuttering, it is time to flush your water heater. Be sure to read the steps below and understand them fully before you proceed, otherwise, it would be best to call your local Toronto plumber for assistance.

6. Once the water has drained completely, shut off the drain valve and open the hosepipe’s cold water supply. Allow the water heater to fill to the halfway mark before turning the water supply off. Repeat the previous step again until the water comes out clear.

7. When the water drains clear from the water cleaner, you can close the drain valve and open the cold water to let the heater fill up again.

8. While the water heater fills up, you should open all the hot water faucets to allow air to escape from the system.

9. Turn the electricity back on, if it is electric, or turn the gas to the original setting if you have a gas heater.

Once you have completed these steps, you’re done. By taking these simple steps, years can be added to your water heater and its efficiency to your water heater.
