Do I Need to Flush My Water Heater?

Have you ever overheard a neighbor talking about flushing their water heater? Many people haven’t had their water heater flushed – ever. You might have asked yourself if you need to be flushing your water heater at all. In this article, we’ll go over if flushing your water heater is necessary, and if it is, why.

Your water heater deals with a lot of stress, much like your car does. And like your car, it needs regular maintenance to run at its best for as long as it should. Your car needs a regular oil change to get rid of old oil that’s filled up with gunk and grit over time. For your water heater, a regular flush does the same thing.

As water runs through your water heater, it leaves behind minerals like calcium. Those minerals settle and build up in the bottom of the tank. This creates a layer of sediment that can get thick enough to reduce the amount of water your tank can heat. Also, the heating element of a water heater is at the bottom of the tank. If the heating element gets blocked by sediment, then your water heater has to work harder to heat the water.

A plumber in a branded shirt works underneath a water heater in a tight, yellow-walled space, performing essential water heater maintenance.

That’s why most manufacturers recommend flushing your water heater once a year. It’s a simple step that helps prevent bigger problems down the road—like sediment buildup, uneven heating, or early breakdowns. Regular maintenance like this can actually add years to your water heater’s life and save you from costly repairs or premature replacement.

The good news? Flushing your water heater is a quick, straightforward job. A licensed plumber can take care of it for you—no problem. And if you’re comfortable with DIY projects, it’s something many homeowners can handle themselves. Either way, it’s a small step that goes a long way toward helping your water heater last for years to come.
