A failing water heater can go from minor annoyance to flooded basement quickly. Most give warning signs first, if you know what to watch for.
Key takeaways
- Most tank water heaters last 8–12 years.
- Rusty water, rumbling, and moisture at the base are warning signs.
- We document the unit's age and safety connections on every inspection.
How long they last
A typical tank water heater lasts 8 to 12 years. Knowing the install date, which we record from the data plate, tells you whether you're buying time or buying a replacement soon.
The warning signs
Rusty or discolored hot water, rumbling or popping from sediment, moisture or corrosion at the base, and inconsistent temperatures all point to a unit nearing the end.
Safety matters too
We also check the temperature-and-pressure relief valve and discharge piping, which are important safety components that are sometimes installed incorrectly.
