How Long Do Well Pumps Last?

Quick answer: Most well pumps last 8 to 15 years. Submersible pumps (set deep in the well) usually run 8–15 years, while above-ground jet pumps often last 10 years or more. How long yours lasts depends on the pump type, your water quality, how often it runs, and how well it’s maintained. Want the differences between the two?

What is the average lifespan of a well pump?

A well pump’s life is usually measured in years of steady use, not a fixed number. As a general rule, plan for 8 to 15 years from a quality pump that’s sized correctly and cared for. The exact pump in your home matters, though, because the two main designs don’t age the same way.

Here’s a quick look at typical lifespans for the main parts of a well system:

Component	Typical lifespan	What shortens it
Submersible well pump	8–15 years	Sediment, frequent cycling, a low-quality unit
Jet pump (above ground)	10+ years	Running dry, wrong sizing, poor ventilation
Pressure tank	5–10+ years	Waterlogging and pressure problems
Pressure switch	5–10 years	Corrosion and electrical surges

Submersible pumps sit inside the well casing, while jet pumps mount above ground—the U.S. EPA’s overview of private wells explains both designs. If you’re choosing a new unit, our submersible pumps page covers your options.

What affects how long a well pump lasts?

Several everyday factors decide whether your pump reaches the high end of its range or wears out early:

• Water quality. Sand, silt, and iron grind down pump parts over time.
• How often it cycles. A pump that switches on and off too frequently wears out faster—often a sign of a failing pressure tank.
• Pump sizing. A pump that’s too small for your home runs constantly and burns out early.
• Build quality. A well-made pump simply lasts longer than a budget unit.
• Power issues. Surges and unstable voltage are hard on the motor.
• Regular checks catch small problems before they kill the pump.

How can I make my well pump last longer?

A little care goes a long way. To get the most years out of your pump:

• Test your water and address heavy sediment or iron with proper filtration.
• Keep an eye on water pressure and fix cycling problems quickly.
• Have the system inspected periodically, especially as it passes the 8-year mark.
• Make sure the pump is correctly sized for your household’s water use.

Wells and pumps also lose performance as they age. Penn State Extension notes that routine maintenance helps keep water flowing and that a noticeable drop in output is a sign the system needs attention. Catching that early often means a repair instead of a full replacement.

What are the signs a well pump is wearing out?

As a pump nears the end of its life, it usually gives you warnings:

• Weak or dropping water pressure
• Air spitting or sputtering from faucets
• The pump runs constantly or short-cycles
• A rising electric bill with no other explanation
• Sandy or cloudy water

If you notice these, don’t ignore them. Our guide on the signs your well pump needs repair walks through each one, and prompt well pump repair can sometimes add years to a pump that’s struggling.

Should I repair or replace an aging well pump?

If your pump is under 8 years old and the issue is a single part, repair is usually the better value. Once a pump is past 10–12 years and failing often, replacement tends to cost less over time and gives you a more reliable water supply.

Cost is part of the decision. You can compare a submersible well pump replacement cost against typical well pump repair costs to see which makes sense for your situation. When in doubt, an inspection will tell you exactly where your pump stands.

Frequently asked questions

How long do submersible well pumps last?

A quality submersible pump usually lasts 8 to 15 years. Clean water, correct sizing, and steady power help it reach the higher end of that range.

How long do jet pumps last?

Above-ground jet pumps often last 10 years or more. Because they’re easier to reach, they’re also simpler and cheaper to service along the way.

Can a well pump last 20 years?

It’s possible but uncommon. A few well-maintained pumps in ideal conditions reach 20 years, but most are replaced before then as parts wear out.

How do I know when to replace my well pump?

Frequent breakdowns, an older pump (10+ years), weak pressure, and rising repair costs all point toward replacement. An inspection confirms it.

Conclusion / TL;DR

• Most well pumps last 8–15 years; submersibles 8–15, jet pumps 10+.
• Water quality, cycling, sizing, build quality, power, and maintenance all affect lifespan.
• Regular care and prompt repairs can add years to your pump.
• Watch for weak pressure, sputtering, constant running, and rising electric bills.
• Repair newer pumps; replace pumps past 10–12 years that fail often.
