Well pump repair or replace
The published repair costs set against the published replacement costs, and the specific repairs where replacing is the cheaper decision.
Well pump repair costs a national average of $450, with most jobs between $300 and $600. Replacing a well pump costs a national average of $1,800, with most between $1,000 and $2,500.
Compare only those two numbers and you repair every time. The decision gets more interesting once you look at what individual repairs cost, because several of them approach or exceed a whole new pump.
| Repair | Replace or install | |
|---|---|---|
| National average | $450 | $1,800 |
| Average range | $300 to $600 | $1,000 to $2,500 |
| Minimum | $150 | $200 |
| Maximum | $1,500 | $20,000 |
The $20,000 ceiling on replacement is a windmill water system, not a conventional pump.

Where the two tables cross over
Set the repair list against the replacement list and the picture changes. This is our own comparison of the two published sets.
| Repair | Cost | Verdict |
|---|---|---|
| Check valve, pressure switch, pressure gauge | $150 to $200 | Repair. No serious argument, at roughly a tenth of a replacement. |
| Motor start capacitor | $150 to $300 | Repair, but if the motor itself is suspect ask about the pump's age first. |
| Foot valve, pump sleeve | $150 to $500 | Usually repair, unless the pump has to be pulled anyway. |
| Control box, well cap and seal | $300 to $600 | Repair, though now within reach of a shallow-well jet pump replacement at $400 to $1,000. |
| Well injector | $500 to $1,000 | Marginal. Overlaps entirely with a shallow-well jet pump replacement. |
| Pressure tank | $800 to $1,500+ | Not a pump decision at all. See the note below. |
Our reading of the two published cost sets, not published guidance.
A discrepancy in the published figures, stated rather than hidden
The two sources disagree on pressure tanks. The repair guide lists pressure tank replacement at $800 to $1,500 or more. The replacement guide lists a pressure tank as a component at $500 to $1,000.
We have not reconciled that, and we are not going to quietly pick the more convenient number. The likely explanation is that one figure includes the labour of a standalone visit and the other prices the tank as part of a larger job already underway, which would itself be a useful thing to know when reading a quote. Treat $500 to $1,500 as the honest span and ask your contractor which situation you are in.
The factor the cost tables miss
On a submersible pump, most of the labour is pulling several hundred feet of drop pipe out of the borehole. That labour is the same whether the technician goes down to change one part or to fit a whole new pump.
So the real question on an older submersible is not whether this repair is cheaper than a replacement. It is whether you expect to pull the pump again within a few years. If the answer is yes, doing it once is usually cheaper than doing it twice, even when each individual repair looks like the better deal in isolation.
On shallow-well jet pumps, which sit above ground, this does not apply and the repair-versus-replace arithmetic is exactly what the tables say.
