Pool Pump Repair · RAIL Licensed
A Dead Pump Turns a Pool Green in Days
In the Houston heat, your pump is the one piece of equipment that can't sit broken. No circulation means no filtration — and a clear pool can turn green in under a week. When it starts grinding, leaking, or won't prime, fast diagnosis matters.
Admiral Pool Service is RAIL-licensed (Texas Residential Appliance Installer License) — required for legal electrical work on pool equipment. We diagnose pump issues accurately, repair to spec, and tell you honestly when a repair beats a replacement.
Same-day pump diagnosis available
Most pump repairs done in a single visit. We stock common parts on the truck.
Pool Pump Problem? Here's What It Means.
Use this diagnostic guide to understand what's happening — then let a RAIL-licensed tech fix it right.
Loud grinding or screeching
Likely cause: Worn bearings, debris in the impeller, or a failing motor
The fix: Bearing replacement, impeller clean-out, or motor swap if the damage has spread
Urgency: High — running it further causes more damage
Won't prime or loses prime
Likely cause: Suction-side air leak, clogged impeller, or low water level
The fix: Pressure-test the suction side, replace the lid o-ring or failing union, clear the impeller
Urgency: High — the pool goes green fast without circulation
Won't turn on at all
Likely cause: Tripped GFCI, dead capacitor, failed motor, or timer/automation fault
The fix: Trace the electrical fault; a capacitor swap fixes most no-start pumps in one visit
Urgency: High — no circulation means no filtration
Trips the breaker
Likely cause: Failed capacitor, shorted or seized motor, or a wiring fault
The fix: Electrical diagnosis first — replace the capacitor or motor, repair wiring to code
Urgency: High — electrical hazard, don't keep resetting it
Motor hums but won't start
Likely cause: Failed start capacitor or seized bearings
The fix: Start capacitor replacement; if bearings are seized, motor repair or replacement
Urgency: High — the motor can burn out within minutes
Low flow or weak return jets
Likely cause: Clogged impeller, dirty filter, or an undersized pump
The fix: Clear the impeller and filter; right-size the pump if it's undersized for the pool
Urgency: Medium — reduces filtration and chemical mixing
Electric bill spiked
Likely cause: Single-speed pump running long hours, or a pump straining against a restriction
The fix: Clear the restriction, or upgrade to a variable-speed pump
Urgency: Medium — a VS upgrade pays for itself in 12–24 months
Visible water leak at the pump
Likely cause: Failed shaft seal, cracked housing, or a loose union fitting
The fix: Shaft seal replacement is the usual fix; tighten or replace unions, replace housing if cracked
Urgency: Medium — worsens and can ruin the motor
Pump basket won't fill with water
Likely cause: Air leak or loss of prime on the suction side
The fix: Find and seal the air leak — lid gasket, valve stem, or suction plumbing
Urgency: Medium — the pump runs dry and overheats
Motor overheats or shuts off
Likely cause: Electrical overload, poor ventilation, a failing motor, or a VS drive fault
The fix: Diagnose the electrical load and drive; repair or replace the motor before it seizes
Urgency: High — stop running it until it's diagnosed

- Shaft seal replacement (prevents leaks)
- Impeller cleaning or replacement
- Full motor swap with OEM parts
Priming & Suction Issues
A pump that won't prime or loses prime is one of the most common pool problems in the Houston heat. We track down the air leak.
- Lid o-ring and gasket replacement
- Suction-side air leak detection
- Check valve inspection and replacement
- Skimmer and main drain line clearing
- Pump basket and strainer cleaning
Should You Repair or Replace?
A capacitor, seal, or bearing is usually a straightforward repair. But if a single-speed motor has failed, upgrading to a variable-speed pump is often the smarter money — here's why Houston homeowners make the switch:

Upgrading to a Variable-Speed Pump
If your single-speed motor has failed, put the repair money toward a variable-speed pump instead. A VS pump running Houston's long summer hours typically cuts pump electricity by up to 80%, so the upgrade pays for itself in 12–24 months. We right-size, install, and program Pentair, Hayward, and Jandy variable-speed pumps — with the electrical done to code by RAIL-licensed technicians.
