Your water heater is one of the most important appliances in your home. It provides warm water for your daily shower and helps keep your laundry and dishes clean. It’s not often that we think about our water heaters until something goes wrong. But just like any other appliance in your home, it needs to be properly maintained.

One of the most important maintenance tasks for your water heater is flushing it. Over time, sediment and minerals build up in your tank, which can cause a number of problems. If you’re not sure whether your water heater needs to be flushed, keep reading to find out.

Signs Your Water Heater Needs to Be Flushed

Strange Noises

If your water heater emits loud popping or cracking sounds, it’s a sign that there may be a buildup of sediment in the tank. This can cause hot spots, which cause the tank to expand and contract as it heats and cools down.

Water That Smells or Tastes Strange

If you notice a metallic or sulfur-like smell or taste coming from your hot water faucet, it’s a sign that you may have sediment buildup in your tank.

Slow Recovery Time

If you find that your hot water supply is running out faster than usual or your water isn’t as hot as it used to be, this is a sign that your water heater may need to be flushed.

Rusty Water

If you notice rusty water coming from your hot water faucet, it’s a sign that your water heater may be corroding from the inside out. This can lead to leaks and other problems if left unchecked.

Age of Your Water Heater: If your water heater is over 10 years old and has never been flushed, it’s likely that it needs to be flushed.

How to Flush Your Water Heater

It’s important to note that flushing your water heater is not a DIY job and should be left to a professional plumber. A plumber will first turn off the power supply to your water heater to prevent any accidents. They will then drain the tank of all the water and sediment buildup. After that, they will refill the tank with fresh water, turn the power back on, and check for any leaks.


Flushing your water heater on a regular basis can increase its lifespan and prevent costly repairs. If you notice any of the signs mentioned above, it’s a good idea to call a professional plumber to inspect and flush your water heater.
