Should I repair or replace my pool pump?
Pool pump repairs commonly cost $100–$700. A complete replacement often costs $300–$1,600 installed, with variable-speed equipment, electrical work, replumbing, and premium controls pushing higher.
Repair a newer pump when the housing is sound and one seal, capacitor, bearing, impeller, or motor component failed. Replace an older, cracked, repeatedly failing, or inefficient single-speed pump when repair approaches a large share of installed replacement cost.

Tell us whether the pump leaks, hums, trips, or stops circulating. We review the request for one matched local pool-repair pro when coverage is available.
Pool pump repair and replacement scenarios
Shaft seal or small plumbing leak
$100–$300How to tellWater drips beneath the motor or around a union while the pump otherwise runs normally
The fixReplace the seal or fitting and inspect bearings for water damage
Capacitor, switch, or minor electrical fault
$150–$400How to tellPump hums, starts intermittently, or needs help starting without a seized shaft
The fixTest the electrical supply and replace the failed control component
Impeller, bearing, or motor repair
$250–$700How to tellGrinding, screaming, weak flow, overheating, or a motor that trips after starting
The fixOpen the wet end, clear or replace the impeller, and repair or replace the motor as diagnosed
Standard pump replacement
$300–$1,600 installedHow to tellCracked housing, failed motor plus aging wet end, repeated repairs, or obsolete parts
The fixInstall a correctly sized replacement and verify flow, valves, bonding, and electrical requirements
Variable-speed upgrade or equipment-pad changes
$1,200–$3,000+ installedHow to tellNew controls, replumbing, electrical changes, automation, or a premium high-flow application is required
The fixSize the pump to the hydraulic system rather than simply matching the old horsepower label
What to check before replacing the pump
- Clean the skimmer and pump baskets and confirm the pool water is at least halfway up the skimmer opening.
- Confirm the valves are open and the filter is not creating an abnormal restriction.
- Note the model number, age, error code, noise, leaks, and whether the breaker trips immediately or after running.
- Ask for separate prices for the diagnosed repair, a like-for-like replacement, and any variable-speed upgrade.
Unlock the hiring checklist
Use this before you call a pool repair, so you know what to ask and what to avoid.
Call a pro when…
- The breaker trips, wiring overheats, or the motor smells burned
- The pump runs dry, repeatedly loses prime, or cannot establish circulation
- The housing is cracked or water reached the motor bearings
- A variable-speed replacement requires electrical, bonding, controls, or replumbing changes
- You cannot distinguish a pump failure from a suction leak or filter restriction
Repair or replace?
Repair usually wins when the pump is relatively new, the wet-end housing is sound, parts remain available, and one serviceable component failed. Replacement usually wins when the housing is cracked, the motor and wet end are both failing, parts are obsolete, the pump has repeated leaks or bearing damage, or the installed repair quote approaches roughly half to two-thirds of an efficient replacement.

Related questions
How long does a pool pump last?
Service life varies with run time, water chemistry, ventilation, freeze exposure, and whether leaks reach the motor. Many pumps last roughly 8–12 years, but seals and bearings may need attention sooner.
Can I replace only the pool pump motor?
Yes when the wet-end housing, diffuser, impeller, and seals are sound and a compatible motor is available. Price the motor and seal work against a complete variable-speed replacement before deciding.
Does a larger pool pump work better?
Not automatically. An oversized pump can waste energy, create excess filter pressure, and exceed plumbing or equipment flow limits. Size the pump to the pool's hydraulic system and required flow.
