Is Flushing Sediment from Your Water Heater on Your Maintenance List?


Owning a home comes with a long list of maintenance chores that often seem boring or unnecessary. If flushing your water heater is one of these “unnecessary” chores that you’ve been skipping, you may be in for a very unpleasant surprise.

Is it Really Necessary?

Yes. All hot water heaters need to be flushed at least once per year – more often if you have a large family. If you have more than two people living in the home, you need to flush every eight months. With more than six people in a home, you should flush the heater every six months to remove sediment buildup. More people using hot water in the home means more work for the heater. The more water that passes through the heater, the more sediment can build up.

Why is Sediment a Problem?

Flushing your water heater is necessary because of sediment buildup. Sediment comes from impurities and minerals in your water. Water is never 100 percent clean. Even though you may not be able to see these particles, they will accumulate at the bottom of your heater. Water also contains minerals such as magnesium, calcium and iron that cause rust and sediment.

Sediment is a problem because it causes your heater to be inefficient. Gas heaters have a heating element at the very bottom of the tank. Electric heaters have two elements, with one in the lower portion of the tank. Heat from the heating elements has to percolate up through this sludge of sediment, making your heater work harder. You will often hear rumbling and popping from your water heater when sediment has built up to this level.

Don’t wait until your heater reaches this condition. By this time, your heater is in dire need of maintenance, and sediment could have also leaked out into your home’s pipes. This leakage can cause clogs in faucets and a buildup in your pipes, lowering your home’s water pressure.
