How long it lasts
DOE's 2024 rule estimates an average lifetime of around 15 years for storage water heaters. HUD's 2000 guide gives about 11 to 13 years for gas-fired tanks and about 14 for electric ones, and PNNL (2013) says water heater life is generally 8 to 20 years.

What to put in your request
- What is wrong, in your own words: what you see, hear or smell, and when it started.
- Whether you want a repair or a replacement (or are not sure yet).
- How soon: an emergency, the next few days, or a set timeframe.
- The ZIP code of the home.
- Whether you own or rent the home.
- The fuel it runs on: gas, electric or propane.
- Photos of the problem area, taken only where you can stand safely.
- A clear photo of the unit's model plate (the data plate or label), if you can reach it safely.

What shortens a water heater's life?
PNNL (2013) says water heater life is generally 8 to 20 years, varying with factors including type and water quality, and that soft water can rust ferrous components and lead to leaks and premature failure.
(Pacific Northwest National Laboratory (DOE), 2013) (Pacific Northwest National Laboratory (DOE), 2013)
Can you test a water heater's relief valve yourself?
HUD's guide says the pressure relief valve can be tested by pressing the test lever, but warns it may stick open.

What does soot on a water heater mean?
