How to flush sediment from your water heater

Cleaning a water heater’s tank is very important aspect of maintenance. In this article you can discover the best methods to safely flush your water heater’s tank. Also, you can learn about some of the advantages of this maintenance work.

Materials Required to flush sediment from your water heater

You most likely already have several of the materials needed to flush your water heater.

  • A bucket
  • A rubber hose
  • Work gloves

Step 1: Turn off the power.

The first step to flush sediment from your water heater is crucial. If your water heater runs on gas, put the gauge to the pilot setting. If you have an electric water heater, shut off the electricity. You accomplish this by turning off the corresponding circuit breaker in your breaker box. Turning off the power to your water heater is an important safety precaution for this project.

Step 2: Turn on a hot water faucet in your home

Turn on the hot water faucet on your bathroom sink. Turning on the hot water might help to eliminate air bubbles from your water heater tank. This easy action will allow it to drain completely. Wait a minute or two, and you can turn off the faucet.

Step 3: Turn off the cold water valve

A water heater’s cold water valve is situated most of the times on top of the unit. It is possible to have a label or even a blue handle that indicates it is the cold water source. You can turn OFF the cold water valve.

Step 4: Attach a hose to the water heater

The next step is to find the spigot on your water heater and connect your hose to it. This spigot appears to be linked to a home’s outer wall. You may use a standard garden hose or get a shorter rubber hose to reduce the amount of slack. Next, place the hose’s end in a bucket to allow water to drain.

If your water heater is located on a shelf several feet above the floor, gravity will assist in draining the water. Alternatively, if your water heater is on the floor in a basement or somewhere else, it may not drain as quickly. Some water heaters require a pump to empty.

When you attach the hose, numerous drops of water may emerge from the spigot immediately away. You can place the hose’s end inside your bucket before linking the other end of the hose to the spigot.

Step 5: Start draining the water heater’s tank

After connecting your hose to the spigot, turn the lever above it to open the valve. Make sure the bucket is secure on the floor so it doesn’t tip over when the water fills it.

Look at the water that comes out. Is this mainly clear? If so, this is a positive indicator. It suggests there isn’t much sediment left in your water heater’s tank. However, if you notice black water with a lot of debris, your water heater may be malfunctioning. If this is the case, you should have your water heater inspected by a certified plumber. After draining all of the water from your water heater tank, turn off the valve.

Step 6: Flush the System

Now it is time to flush the system with cold water. Reach up and turn on the cold water valve. Cold water will travel through the system, loosening any residual silt. This step is beneficial in removing silt from the tank’s bottom.

Take around five minutes to flush your water heater tank with cold water. Then, turn off the cold water valve and open the valve on your hose. Of course, make sure the end of your hose is still in the bucket.

Is there still a lot of sediment in the water flowing from your tank? If that’s the case, you may need to flush and drain the tank again.

Detach the hose and turn on the water heater

After you’ve finished draining your water heater tank for the final time, shut the valve. Then detach the hose from the spigot. After turning on the cold-water valve, restart the bathroom faucet. Finally, switch on the gas or electricity to your water heater. Check your drain valve for a few minutes to confirm that there are no drips.
