How long does a well pump last?

How long a well pump lasts

Published service life: 15 years. Roots plans for: year 15.

Service life is a planning horizon, not an expiry date. It tells you when to start budgeting, get a second quote, and stop paying for repairs on something near the end — not the day it stops working.

What changes this

The figure is for the PUMP, which is the part that gets replaced — the well itself does not wear out. A submersible pump means a rig on site to pull it, so the labour is a large share of the cost and it is worth planning for.

• InterNACHI's Standard Estimated Life Expectancy Chart for Homes (Well Pump). Single source — the NAHB study does not cover private well equipment.

Service-life figures are typical estimates drawn from published industry references. Where a second reference covers the component, the figure is cross-checked against it and any disagreement is set out above; where only one reference covers it, that is stated. Actual life varies with installation, water quality, climate, and maintenance, and these figures shouldn't be relied on for insurance, lending, or warranty decisions.

Maintenance is what decides where in the range you land

The published range is wide for a reason: two identical units, installed the same day, routinely fail years apart. What separates them is upkeep.

For a well pump, the tasks that matter most:

• Test well water quality — Bacteria and nitrates are invisible and tasteless. Annual testing is the only safeguard.

Roots tracks the age of every component in your home alongside the upkeep that extends it, so the replacement is a planned expense instead of an emergency.
