Identifying Water Heater Sediment Buildup

Can’t remember the last time you checked on your water heater? Without regular cleaning, your water heater will collect sediment and mineral buildup, which can cause hot water issues in your home.

Check Your Water Heater For Sediment Buildup

Sediment, minerals, and scale can settle and build up in the bottom of your water heater tank. This makes your unit work harder by preventing the burner from heating your water.

Checking for sediment build up in your water heater is important to extend the lifespan of your unit.

How to check for water heater sediment buildup

  • If you don't have a tub, run the shower instead (this will take a bit longer). Leave the rub or shower running while you check on your hot water heater.

  • Stand close enough by the tank to hear, then wait for the burner to come on. A minute or two after the burner starts, you'll hear a crackling or popping noise.

If sediment buildup in your water heater isn't the issue, consider other causes of strange noises and no hot water.

What to Do if You Have Water Heater Sediment Buildup

Follow the steps outlined above and then flush your water heater. If you're not sure how to do this correctly, you can connect with one of our Remote Assist technicians to guide you through the process.
