How to Flush Your Water Heater: A Step-by-Step Guide

Have you ever wondered if flushing your water heater actually helps? The truth is flushing your water heater regularly does help to maintain efficiency and prolong its lifespan. Over time, sediment builds up at the bottom of the tank, which can reduce the heater’s efficiency and increase energy bills. So, as expert Murrieta plumbers, we at Donnie’s Plumbing want to guide you through this important maintenance process. Whether you’re handling it yourself or need professional assistance, this guide will help you understand the steps involved.

Why You Should Flush Your Water Heater

Sediment buildup is inevitable in any water heater, especially in hard water areas like Murrieta. If left unattended, it can cause:

  • Reduced efficiency
  • Strange noises (rumbling or popping)
  • Premature failure of the water heater

Step-by-Step Process to Flush Your Water Heater

1. Turn Off the Power Supply

  • For electric water heaters: Turn off the breaker at the electrical panel.
  • For gas water heaters: Set the thermostat to “pilot.”

It’s crucial to make sure your water heater is not actively heating water while you perform the flush. Safety comes first!

2. Shut Off the Water Supply

Locate the cold water valve at the top of the water heater and turn it off. This will stop water from flowing into the tank during the flush.

3. Connect a Garden Hose to the Drain Valve

At the bottom of your water heater, you’ll find a drain valve. Attach a garden hose to this valve and place the other end in a safe location, like a nearby drain or outside.

4. Open the Drain Valve

Turn on the drain valve and allow the water to flow out of the tank. Be cautious—the water may be hot! To speed up the draining process, open a hot water tap in your home, as this helps air enter the system, which allows water to flow out more smoothly.

5. Flush the Tank

Once the tank is empty, turn the cold water supply back on for a few minutes to flush out any remaining sediment. You should let the water run through the hose until it’s clear.

6. Close the Drain Valve and Remove the Hose

After the flushing process is complete, close the drain valve and carefully remove the garden hose. Ensure the valve is tightly closed to prevent leaks.

7. Refill the Tank

Turn the cold water supply back on and wait for the tank to fill. Once it’s full, open a hot water faucet in your home to allow any trapped air to escape.

8. Turn the Power Back On

  • For electric heaters, flip the breaker back on at the electrical panel.
  • For gas heaters, turn the thermostat back to its normal setting.

9. Check for Leaks

After restoring power and water to your heater, check around the drain valve and other connections for any signs of leaks.
