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.
