How To Flush A Water Heater: Step By Step

Is your shower turning cold too soon? Seeing sediment in your water? It may be time to flush your water heater. Don't sweat it - the RooterPLUS experts are here to walk you through the process step-by-step.

Flushing your water heater regularly is crucial to keep it operating efficiently and provide plenty of hot water for your home. Here's our simple guide to get the job done right.

Why Flushing Matters

Over time, sediment, minerals and bacteria build up inside your water heater tank. This gunk coats the heating elements, reducing their efficiency. Flushing removes this buildup, restoring your heater's performance.

The benefits of flushing include:

  • More hot water - Remove mineral deposits so your heater works like new.
  • Cleaner water - Flushing gets rid of sediment so your water stays clear.
  • Longer life - Regular flushing helps your water heater last years longer.
  • Avoid repairs - Flushing prevents many problems down the road.

Signs It's Time to Flush

Watch for these clues that your water heater needs flushing:

  • Decreased hot water supply - Showers turn cold too quickly.
  • Discolored or murky water - Sediment or rust color the water.
  • Strange noises - Popping or rumbling from the tank.
  • Reduced efficiency - Takes longer to heat water.

See any of these? Schedule a flush. Yearly is recommended.

How to Flush a Water Heater in 7 Steps

Ready to flush your water heater? Gather a garden hose and bucket and follow these steps:

1. Turn Off Power

Locate the circuit breaker or control panel and switch off power to the water heater. This may require relighting the pilot light later.

2. Shut Off Water

Turn the cold water shut-off valve at the top of the tank to the closed position.

3. Open Hot Water Faucet

Open the hot water tap closest to the heater to release pressure in the tank.

4. Connect Hose

Attach a garden hose to the drain valve near the bottom of the tank. Run the hose to a bucket or drain area.

5. Drain Tank

Open the drain valve and allow the tank to empty. Keep an eye on the drained water's color and clarity.

6. Flush With Clean Water

Once drained, close the drain valve and reopen the cold water shut-off valve. Let clean water run through for 3-5 minutes to rinse sediment.

7. Recheck Water Clarity

Check that the drained water runs clear rather than discolored. Close faucet when done.

That's it! Turn your water heater back on and it should be refreshed and ready to deliver hot water. Contact RooterPLUS if you have any trouble with the process. Our technicians can flush your system properly. Enjoy those hot showers again!

When To Call Your Atlanta Plumber

While it is possible to flush your water heater independently with the necessary skills, tools, and time, sometimes you may prefer to save your effort or guarantee a proper job. In such cases, you can rely on the expertise of our professional team.

Jason has come to my house three times. Each time he was friendly, punctual, and very clear about the cost of repairs and what kind of work was required. At every step he kept me informed. Outstanding service. Would definitely call on Rooterplus again.

Came through for me

I needed to service my septic tank prior to sodding my backyard. I called 2 other companies prior to RooterPLUS, Both showed up with equipment that couldn't do the job. With only a couple day window available, RooterPLUS came through for me the next morning with the right equipment and a professional and pleasant crew.

Doc and Kory assessed the situation and got right to work. They knew exactly what to do and completed the task perfectly. They explained everything throughout the process and pointed out potential issues as they worked. Everything was done to my complete satisfaction and I'll definitely use RooterPLUS in the future for my septic tank needs.

Neighborhood rockstars

We had an issue in my neighborhood where a water main pipe burst, leaving a giant mess of a leak spewing into the street. We called numerous plumbing companies who all said they couldn't get out in a timely manner. RooterPlus! said no problem, we'll be out asap.Josh came out, assessed the situation and said he had to go get some more supplies. He came back with the necessary supplies and got to work. And he worked and worked and worked from 6pm until 4:30 am! He had to call in reinforcements (Josh 2) and they worked hard as a team to repair the issue. Then they came back out only 5 hours later to put the finishing touches on the job.I think I speak for the entire neighborhood when we say THANK YOU SO VERY MUCH for being absolute rockstars and getting our neighborhood back up and running.
