How long does a well pump last?

There is no fixed number — a pump typically has a shorter lifespan than the well itself, and a well can last 20 or more years with proper maintenance. Age alone is not the sign to watch for; changes in performance are.

Can I replace or repair a well pump myself?

No. Pump service, cleaning, disinfection, and flow restoration all require a licensed professional — DIY attempts risk personal safety, damage to the well system, and in some states a regulatory violation.

My water pressure just dropped suddenly — is that the pump?

It is one of the most common early warning signs, but not the only possible cause. A professional needs to check the pump, the pressure switch, and the pressure tank to know which one it actually is.

What's the one sign that means stop and call immediately, not just schedule a visit?

The smell of burned wiring at the wellhead or pump equipment. That's an electrical safety issue, not a routine maintenance item.

Cracked, corroded, or damaged casing, or a broken or missing well cap.

What actually needs a professional vs. what you can check

all require a licensed professional — the NGWA is direct about why: . What you can do yourself: watch for the performance and equipment signs above, and call immediately for any change in your water's , a positive bacteria test result, or visible physical damage at the wellhead.

How long a pump actually lasts

There's no fixed number to plan around. , while a well itself can last with proper maintenance. Watch performance, not the calendar.

If you also test your water annually

A struggling pump can also be the reason a water test comes back different from last year's. See the annual well testing schedule if you're not already on one.
