Drain Sediment From Your Water Heater or Expect a Shortened Life Span

A distraught homeowner called a plumber because her water heater wasn’t heating, and furthermore, it was leaking. Right away, the plumber asked if the homeowner had been draining some of the water from it every year. The puzzled homeowner said, “No. Why?” It turns out that sediment will collect at the bottom of the tank. This creates hot spots on gas-powered heaters that can damage the tank and cause premature failure. On an electric water heater, sediment buildup can cause the lower heating element to fail. So, occasionally draining a water heater will lower energy bills and extend its life. We recommend draining water heaters at least once a year.
