How Long Does a Water Heater Last?

Posted: February 28, 2018

Water heater leak

Studies have shown that 7 out of 10 water heater failures are caused by a tank bursting or failing. If you notice a slow leak from your tank, this means you’re headed for trouble. In most cases, a slow leak indicates that your tank has become weakened by corrosion.

The best thing to do if you notice a leak is to turn the tank’s water supply valve to the off position and then get it inspected as soon as possible.

The average water heater lasts anywhere from 7 to 13 years. A lot depends on the quality of the unit itself, but water quality in your area is important, too. Hard water, which has a high mineral content, can shorten the life of a water heater.

Other trouble signs

  • If it takes longer to heat water, or the water doesn’t get as hot, it’s a good sign you are ready for a new unit.
  • Look for any signs of rust on the tank or in your tap water. (A water tank rusts from the inside out).
  • If you hear rumbling noises from your water heater, this usually indicates sediment has built up in the bottom of the storage tank. This decreases heating efficiency and could eventually cause your water heater to break down. To prevent problems and save money, schedule a maintenance check.
