Most pool pump repairs run $50–300 in parts if you do it yourself, or $150–600 with a pro once you add labor and a trip charge. The common ones: a capacitor is $15–40, a shaft-seal kit $20–60, an impeller $20–60, and a full motor $150–350. My rule: if the repair costs more than half a new pump and the unit is past 8–10 years, replace it.
What Pool Pump Repairs Actually Cost
When someone asks me what a pool pump repair costs, my honest answer is “it depends on which part died and who turns the wrench.” The part is usually the cheap end; the labor and the trip charge are where a small fix turns into a real bill. So I’ll lay out the real part costs first, then the labor math, then the one rule I use to decide whether a pump is worth fixing at all. I spent nine years pricing exactly these repair-versus-replace calls on commercial food-service equipment, and the math on a pool pump is the same conversation I had a hundred times in a supermarket back room.
I’ll tell you up front where my bias sits: I’d rather replace a $20 part on my own pad than pay a service call, and I’d rather scrap a fifteen-year-old pump than keep feeding it parts. Both of those are money decisions, not pride decisions, and I’ll show you how I get there.
The rule I keep coming back to: when a repair runs more than half the price of a new pump and the unit is past 8–10 years old, replacement is the smarter money — you stop paying to keep an inefficient motor limping.
The Common Repairs and What the Parts Run
Capacitor — $15–40 (the cheapest, and one of the most common)
If your pump hums but won’t start, or starts slow, the start/run capacitor is the usual suspect and it’s the best news on this list. The part is $15–40 and it’s a fifteen-minute swap once power is off. I’ve fixed more “dead” pumps with a capacitor than with anything else, and it’s the first thing I check before I let anyone talk about a new motor. My walkthrough on how to test and replace a pool pump capacitor shows the whole job.
Shaft Seal / Seal Plate — $20–60
Water dripping from under the pump where the motor meets the wet end means the mechanical shaft seal is gone. A seal kit with the gasket runs $20–60, and I always replace the seal and its ceramic seat as a set so it doesn’t leak again. The details are in my shaft seal leak guide.
Impeller — $20–60
Weak flow that isn’t a clogged basket or air leak often points at a worn or cracked impeller. The part is modest at $20–60; the work is getting the wet end apart, which the video below shows. A debris-jammed impeller you can sometimes clear for free.
Motor — $150–350
This is the expensive one. Bad bearings (a grinding or screaming pump) or windings that ground out and trip the breaker mean the motor itself. A replacement motor is $150–350 depending on horsepower and type, and a pro will add labor on top. Once you’re spending motor money, it’s worth asking whether a whole new pump makes more sense — I cover that in replacing the pool pump motor.

DIY vs Pro: Where the Real Money Goes
Here’s the part that surprises people. A capacitor is a $15–40 part, but a pro charges a trip fee of $75–150 just to show up, plus $80–150 an hour. So that same fifteen-minute capacitor swap can land at $150–250 on a bill, almost all of it labor and travel. That gap is exactly why I push the simple, safe jobs — capacitor, lid o-ring, seal kit, clearing a clogged impeller — toward doing it yourself if you can be safe around power. I draw my own line at anything requiring me to cut into house wiring; for that I want an electrician, and I say so plainly. But for the wet-end and capacitor work, the part cost is the whole cost when you do it.
Is It Worth Repairing, or Should I Replace?
This is the decision that actually matters, and it’s the one I’ve made for a living. I weigh three things: the repair cost against the price of a new pump, the age of the unit, and how efficient it is. If a sub-$60 seal kit fixes a five-year-old pump, that’s an easy yes. If a pump needs a $300 motor and it’s already twelve years old and single-speed, I’d put that money toward a new variable-speed pump that pays itself back in energy savings instead — see how the numbers shake out in single-speed versus variable-speed pumps. One honest miss from my own past: I once kept repairing an old unit twice in one season before admitting I’d have come out ahead replacing it the first time. Now I run the half-the-cost-and-eight-years rule before I order a part. For new-pump pricing, my pool pump replacement cost breakdown has the numbers, and you can match repair parts by your pump’s model on Inyo Pools’ pool pump parts catalog.
How to Keep Repair Costs Down
Most of what I get called for is preventable. Keep the pump primed so the seal never runs dry. Clean the baskets so the motor isn’t straining. Keep water off the electrical and the motor breathing so the windings last. The cheapest repair is the one you never need, and I’ve watched simple weekly habits add years to a pump that would otherwise have been a motor job.
Frequently Asked Questions
How much does it cost to repair a pool pump?
For a do-it-yourself fix, figure $15–60 in parts for the common jobs (capacitor, seal kit, impeller) up to $150–350 for a motor. With a pro, add a $75–150 trip charge and $80–150 an hour, which puts most repairs in the $150–600 range. The part is usually the small number; labor and travel are the big one.
Is it cheaper to repair or replace a pool pump?
It depends on age and repair cost, and here’s the rule I use: if the repair is more than half the price of a new pump and the unit is past 8–10 years, replace it. A cheap fix on a newer pump is always worth it. Throwing a $300 motor at an old, inefficient pump usually isn’t — that money does more as a down payment on a variable-speed unit.
How much does a pool pump motor cost to replace?
The motor itself runs $150–350 depending on horsepower and whether it’s single- or variable-speed. Doing it yourself, that’s the whole cost. With a pro, expect labor and a trip charge on top, often landing the job around $300–500. Because it’s the priciest common repair, it’s the point where I always stop and weigh a full replacement.
Can I repair a pool pump myself to save money?
For the common jobs, yes, and that’s where the savings are. A capacitor, a shaft-seal kit, an impeller, or a lid o-ring are all DIY-friendly if you kill the power first and can be safe around electricity. I do all of those on my own pump. The one place I stop is house wiring — that I leave to an electrician, every time.
How long should a pool pump last before it needs replacing?
A well-maintained pool pump generally lasts 8–15 years; the motor is usually what gives out first. If yours is in that window and facing an expensive repair, weigh replacement — especially since a new variable-speed pump will cut your power bill enough to help pay for itself over the years you’d keep it.
