What Does Flushing a Water Heater Involve?
Before we dive into the steps of how to flush a water heater, let’s first talk about what the process involves. Flushing your water heater is essentially draining out all of the water and sediment that has built up in the tank over time. This helps to prevent corrosion, extend the life of your water heater, and improve its efficiency. It’s important to note that flushing your water heater is a maintenance task that should be done at least once a year, depending on how hard your water is. Now, let’s move on to the steps of how to flush a water heater!
Step 1: Turn Off the Power
Before you begin flushing your water heater, you’ll need to turn off the power to it. If you have an electric water heater, you’ll want to turn off the electricity to the unit at your main circuit breaker. If you have a gas water heater, you’ll need to turn off the gas supply valve located near the unit.
Step 2: Turn Off the Water Supply
Next, you’ll want to turn off the water supply to your water heater. You’ll typically find the shut-off valve near the unit or on the main water line.
Step 3: Turn On the Hot Water Faucet
To prevent a vacuum from forming in the lines, you’ll want to turn on a hot water faucet in your home. This will allow air to enter the system and help the water drain more easily from the tank.
Step 4: Attach a Hose to Drain Valve
Locate the drain valve at the bottom of your water heater and attach a garden hose to it. Run the other end of the hose to a drain or outside.
Step 5: Open the Drain Valve
Once the hose is attached, open the drain valve and let the water drain out of the tank.
Step 6: Flush the Tank
Once the tank is empty, turn on the water supply for a few minutes to flush out any remaining sediment. Repeat this step until the water runs clear.
Step 7: Refill the Tank
Close the drain valve and remove the hose. Turn on the water supply and let the tank refill. Make sure to turn on the hot water faucet you opened earlier to allow the air to escape from the tank.
