Pool Pump Repair and Replacement
Pool pump repair covers a pump that will not prime, leaks at the shaft seal, screams on startup, trips a breaker, or shows a drive fault on a variable speed model. We diagnose first, then hand you a repair price and a replace price in writing, so the decision belongs to you rather than to us.
Signs you need this
- The pump pot fills halfway and stops
- The pump is pulling air on the suction side. A dry lid o ring, a loose lid, a low water level, or a cracked fitting are the usual causes, and all four are cheap.
- Water drips from between the motor and the wet end
- That is the shaft seal. Left alone the water works into the motor bearings and turns an inexpensive part into a full motor replacement, usually within a few weeks.
- A grinding or howling noise that gets louder as it runs
- Worn bearings. The motor is on borrowed time, and it normally seizes during the hottest week of the year, because heat is what finishes bearings off.
- The breaker trips a few minutes after startup
- A heat related electrical failure, often a failing capacitor or a motor drawing too much current. Resetting it repeatedly stresses the circuit and can damage a drive.
- A variable speed pump shows a drive fault and restarts itself
- Drives log real fault codes. Reading the code tells us whether it is overheating, a wiring problem, or genuine drive failure, and that decides repair against replace.
What is included
Included in the plan
- On site diagnosis of priming, suction, electrical, and drive faults
- Lid, o ring, and pump pot inspected for the air leak behind most no prime calls
- Shaft seal, impeller, and diffuser checked and priced individually
- Motor tested for bearing wear, capacitor failure, and overheating
- Variable speed drive faults read and interpreted, not simply reset
- Written repair price and replace price before anything is opened further
Extra, and always in writing first
- Full pump replacement, including a conversion to variable speed
- Plumbing modification when a new pump does not match the old footprint
- Electrical work past the pump, which we will tell you belongs to an electrician
- Freeze damage repair on cracked fittings and a split volute
Extras need a written yes with the dollar amount before the work starts. No verbal add ons, ever.
What it costs
$175 to $275+
Trip plus diagnosis runs $175 to $275+ and credits toward approved work. A seal, o ring, or capacitor repair usually lands well under a replacement. Full pump replacement runs $900 to $2,400+ depending on horsepower, whether it is variable speed, and how much plumbing has to be rebuilt to fit it.

What moves the price
A range is only honest if you can tell which end you are on. These are the things that decide it.
| Factor | What it does to the number |
|---|---|
| Horsepower and pump type | A small single speed replacement sits at the bottom of the replacement band. A large variable speed unit that talks to automation sits at the top, and the difference is the pump. |
| Plumbing rework needed | New pumps rarely match an old footprint. If suction and return have to be rebuilt to line up, that adds pipe, fittings, and cure time before anything can be tested. |
| Wet end failure or motor failure | Seals, o rings, impellers, and diffusers are modest parts. A failed motor or drive is most of the cost of a new pump, which is usually the point where replacement wins. |
| Electrical condition at the pad | Corroded conduit, a marginal breaker, or undersized wiring has to be corrected before a new pump goes in. Work past the pump belongs to a licensed electrician and we say so. |
Rebuild the old pump or replace it
| Repair | Replace | |
|---|---|---|
| Best case today | A seal and an o ring, running again this visit | A quieter pump and a lower power bill |
| On a pump over ten years old | Buys a season, maybe two | Usually the better spend |
| Parts availability | Older models get harder every year | Current models are stocked |
| Power use | Unchanged | Variable speed cuts run cost noticeably |
Short version. On a newer pump, repair almost always wins. On an old single speed needing a motor, replacement pays for part of itself in run cost before it ever pays for itself in reliability.
Our process
Send a photo of the pad
Model numbers and the plumbing layout in one picture let us bring the likely parts, instead of scheduling a second trip to go get them.
Diagnose before disassembly
A pump that will not prime is usually pulling air on the suction side rather than dying. Checking that first has saved a lot of people a pump they did not need.
Two prices, in writing
Repair and replace side by side, with what each one buys you. A twelve year old single speed with a bad seal is a different conversation from a two year old variable speed.
Fix it and verify flow
We do not leave until the pump primes, holds prime, and filter pressure reads where it should for your system and your filter.

Through a North Texas year
- Spring startupPumps that sat all winter show their seal leaks in the first week they run. Finding it in March beats finding it in July.
- June through AugustPeak failure season. Heat kills bearings and capacitors, and a pump down two days in a 100 degree week usually means a green pool on top of the repair.
- FallThe quiet window. Lead times are short, and a pump replaced in October is not one you are chasing during the first hot week of summer.
- The February freezeTwo nights below freezing split volutes and crack fittings on unprotected pads. We see the same failure across Denton County every time it happens.
Our water. Hard water reaches the pump as well. Calcium builds inside the volute and on the impeller vanes, which drops flow before anything sounds wrong. Low water levels in a 100 degree August let the pump run dry for seconds at a time, and running dry is what cooks a shaft seal. Chemistry and water level are not separate from pump life, they are most of it.
Common mistakes we get called to fix
Running the pump dry trying to make it prime
The shaft seal is cooled by water. Thirty seconds dry is enough to score it, so a pump that would not prime because of a lid o ring now needs a seal as well.
Greasing the lid o ring with petroleum jelly
Petroleum products swell and destroy the o ring within a season. Silicone lubricant is the right product and it costs almost nothing next to the air leak a failed o ring causes.
Leaving the pump unprotected before a hard freeze
Water expands as it freezes and a full volute splits. Draining the pump or running it through the freeze is the difference between an inconvenience and a replacement.
What happens during a pool pump repair Flower Mound diagnosis
A pool pump repair Flower Mound call starts with power, water level, and the lid o ring, in that order, because more than half of the no prime calls we run end right there. Then we check the impeller for debris, the shaft seal for a drip, and the amp draw against the motor plate. You get told what failed and why. If it is something you can handle next time, we show you rather than keep it to ourselves.
Ask for the failure before you accept any quote. A loud pump is a symptom, not a diagnosis. On a newer variable speed unit, pool pump repair Flower Mound work is almost always cheaper than replacement and we will push you that way. On an old single speed needing a motor, we will say plainly that a new pump earns back part of its price in run time, and you are free to take that or leave it.
More than half the no prime calls we run in this area end at the lid o ring or the water level, not at the pump. We show the homeowner both, so the next one does not need a truck.

Common questions
My pump will not prime. Is it dead?
Usually not. The common causes are a dry or cracked lid o ring, a loose lid, a low water level, or a clogged impeller, and all four are cheap. A truly failed motor announces itself with noise, heat, or a tripped breaker.
Should I repair or replace?
Age, horsepower, and whether it is single or variable speed decide it. When a repair costs a large share of replacement on an old single speed, replacement usually wins on energy alone. You get both numbers and make the call.
The pump cracked after a freeze. Can that be repaired?
A split volute or a cracked fitting from a hard freeze is a repair, and we see it every winter here on pads left wet and unprotected. Whether it is worth repairing depends on the pump, and we will say so plainly.
