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!

He found the leak quickly and did a quality repair to a poorly joined pipe by the builder. I am very pleased with the work provided. He went the extra mile and also replaced the pine straw that was removed for the repair. Work was NOT cheap but I got what I needed - immediate response and repair. I recommend if you are in a pinch.

We luckily had gravel drainage so he recommended cleaning out our septic tank completely and putting biodegratible in the drainage field. He was here from 4:00-6:30 and explained everything to my husband. In the past when we had our septic tank pumped they did it incorrectly. I feel confident in Steven’s work and we have a 12 month guarantee. It was costly but for what he did worth every penny. Thank you Steven for your expertise job.

I called the office for water leakage on Sunday morning and they schedule me with Technician arrival in 30 mins. Jason reached on time, investigate the problem and able to find the source of leak in few minutes, which was definitely tricky and I believe only an expert eye like Jason can capture it. He walked me over the issue, fixed it and saved my Sunday morning. RooterPLUS is on my speed dial now for any plumbing issues.

It is usually unlikely that you see someone young working hard and have a good attitude along with it. Robert definitely displayed that while he was at work today and I had the pleasure to meet him and tell you about it. Keep up the good work Robert it will pay off!
