How long does a well pump last?
Updated August 2026
A well pump lasts 8–15 years, and the type decides where in that band you land: a submersible pump sitting deep in the well runs 8–15, while an above-ground jet pump wears out sooner at 6–10. Two things age either one, how many times a day it starts and stops, and how much sand and sediment the water carries through it. A pump that short-cycles because of a waterlogged pressure tank can burn out in half its rated life, so the tank and the pressure switch matter as much as the pump itself.
Lifespan by type and situation
| Type or situation | Typical lifespan | Why |
|---|---|---|
| Submersible pump, clean water | 10–15 years | Deep-well workhorse; the sealed motor runs cool |
| Jet pump (shallow or deep well) | 6–10 years | Above ground, harder-working, easier to service |
| Constant-pressure (VFD) pump | 10–15 years | Soft starts reduce cycling stress on the motor |
| Sandy or silty water | Cut 2–4 years | Grit abrades the impellers and the seals |
| Short-cycling from a bad tank | Cut in half | A waterlogged pressure tank runs the motor to death |
| Frequent power surges | Shortened | A surge can cook a submersible motor outright |
Signs yours is near the end
- Water pressure that sputters, drops, or comes out in air spurts
- The pump running constantly, or clicking on and off rapidly (short-cycling)
- Sand, grit, or cloudy water showing up at the taps
- Higher electric bills from a motor that never fully shuts off
- Whining, grinding, or new noise from a jet pump or the pressure tank
- Pressure that will not build to the normal 40–60 psi cutoff
How to add years
Most well pumps die from cycling, not age, so protecting the motor from needless starts buys the most life. Keep the pressure tank charged to the right air setting and swap the pressure switch when it chatters; a healthy tank lets the pump run in long, easy pulls instead of hammering on and off. Testing pressure and draw yearly catches a failing tank early, and a sediment filter or better intake screen keeps grit off the impellers. Run through the well pump maintenance checklist each spring, and if the pump is over 10 and short-cycling, read the cost of skipping service before it strands you without water.
What it costs to replace: plan on $1,000–2,500 installed. Replacing on your own schedule, before it fails, is almost always cheaper than the emergency version. The home maintenance cost calculator helps you set the money aside before it comes due.

Why do well pumps short-cycle, and does it really shorten their life?
Short-cycling means the pump switches on and off many times a minute instead of running in steady pulls, and it is one of the fastest ways to kill a motor. The usual cause is a pressure tank that has lost its air charge or a ruptured bladder, so there is no cushion of pressurized water between cycles. Each start draws a heavy surge of current and heat, and thousands of extra starts a day can halve an 8-year pump. Recharge or replace the tank the moment you notice rapid clicking.
Submersible or jet pump: which lasts longer?
Submersibles, usually. A submersible pump sits underwater at the bottom of the well, stays cool, and commonly runs 10–15 years; a jet pump lives above ground, works harder to pull water up, and averages 6–10. The trade is access: a jet pump is easy and cheap to reach and service, while pulling a submersible means hauling pipe and wire out of a deep well. For deep wells a submersible is the standard; shallow wells often use a jet pump by necessity.
How much does it cost to replace a well pump?
Replacing a well pump runs $1,000–2,500 installed for most homes. A shallow-well jet pump swap sits at the low end; a submersible in a deep well costs more because a crew has to pull hundreds of feet of drop pipe and wire to reach it. Expect to add for a new pressure tank, switch, or wiring if those failed too. Depth is the big variable: very deep or hard-to-access wells can push a submersible replacement past $3,000.
Can a well pump be repaired instead of replaced?
The wear parts around it often are. A jet pump's pressure switch, impeller, or motor capacitor can be swapped for a fraction of a full replacement, and a bad pressure tank is a straightforward fix. A submersible is different: because reaching it means pulling the whole assembly out of the well, most owners replace rather than rebuild once it is already up. If the pump is past 10 years and out anyway, put in a new one instead of gambling on the old motor.
