Here’s links to a collection of more blog posts about WATER HEATERS: To find the age of your water heater, go to How do I determine the age of my water heater?Also, see our blog post What are the most common installation mistakes with water heater replacement? There are several things you can do to extend the life of an older water heater, such as draining the sediment from the bottom of the tank every couple of years and replacing the sacrificial anode as necessary, but the best way to avoid a water heater failure and subsequent water damage is to just replace it. When insurance companies request a 4-point inspection for older homes, as they are doing more often lately, if the water heater is over about 30 years old they will likely request that it be replaced as a requirement for coverage. It is a proverbial “accident waiting to happen.” Other than a little dust and some discoloration of the EnergyGuide sticker, it doesn’t look it’s age-and that’s the problem. The water heater in the picture above is 28 years old.

Water heater failures cost the insurance company an average of $4,444 per incident, after the deductible is paid.īecause water heaters corrode from the inside of the tank outward, there is often no external sign of it’s deterioration.

More than two-thirds of all water heater failures are due to a slow leak or sudden burst of the tank.

The average age at failure was 10.7 years.

Most water heater failures occur when the water heater has reached its life expectancy and the tank begins to rust and corrode.

Here’s some statistics from the Insurance Institute for Business & Home Safety, an insurance industry research organization:
