Signs it may be time to replace
- The unit is about 10 years old or older.
- Water leaks from the tank body, not just a fitting.
- Hot water looks rusty or smells off.
- You have needed several repairs in a short time.
- The tank runs out of hot water too fast for your household.
Choosing a replacement
You will choose between a traditional tank and a tankless system, and between gas and electric. Size matters: a unit that is too small runs out of hot water, while one that is too large wastes energy. Prescott hard water is worth raising, since scale affects both types.
What to ask for in an estimate
- The exact model, capacity, and warranty.
- Removal and disposal of the old unit.
- Any code updates, such as an expansion tank or a new shutoff valve.
- Whether a permit is required for your address.

Common questions
How long does a water heater last?
Tank models commonly last 8 to 12 years, and tankless units can last 20 years or more with upkeep. Hard water can shorten both.
Should I switch to tankless?
Tankless offers continuous hot water and a long lifespan, but it costs more upfront and needs descaling in hard-water areas. Ask for options on both before you decide.
