Expert Pool Pump Repair & Troubleshooting Services

Your Pool Pump Is the Heart of Your System

At McCool's Pools, we understand that your pool pump is the most critical component of your entire circulation system. When your pump fails or operates inefficiently, everything suffers—water quality deteriorates, chemicals become unbalanced, and your pool quickly becomes unusable. With nearly two decades of experience repairing pool pumps throughout the Phoenix area, our licensed technicians have the expertise to diagnose and fix pump problems quickly and correctly. From strange noises and leaks to complete motor failure, we've seen and successfully repaired every type of pump issue imaginable.

Common Pool Pump Problems We Repair

Pump Won't Start or Prime

When your pump refuses to start or won't hold its prime, it's not just frustrating—it's preventing your entire pool system from functioning. Our technicians systematically diagnose these issues, checking everything from power supply and capacitors to impeller blockages and air leaks in the suction plumbing. We've repaired thousands of non-starting pumps and know exactly where to look based on your pump's symptoms, saving you time and getting your circulation restored quickly.

Noisy Pump Operation

Unusual sounds from your pump—grinding, screeching, humming, or rattling—indicate specific problems that require immediate attention. Bearing failure produces a distinctive grinding or squealing noise that worsens rapidly. A humming pump that won't start often points to capacitor failure. Rattling suggests loose mounting or internal component damage. Our experienced technicians can identify the exact cause by sound alone and provide appropriate repairs before minor issues become complete pump failure.

Pump Leaks and Seal Failure

Water leaking from your pump isn't just wasteful—it can damage the motor, corrode electrical components, and create safety hazards. Most pump leaks originate from worn shaft seals, deteriorated O-rings, or cracked pump housings. We stock common seal kits for all major pump brands and can often complete seal replacements the same day. For housing cracks or severe corrosion, we'll assess whether repair or replacement provides the best value.

Low Flow and Weak Circulation

When your pump runs but doesn't move adequate water, your entire pool suffers. Weak circulation prevents proper filtration, chemical distribution, and heating. Causes range from clogged impellers and worn wear rings to incorrectly sized equipment and plumbing restrictions. Our diagnostic process identifies exactly where flow is being lost and what repairs will restore proper circulation to your system.

Overheating and Electrical Issues

A pump that repeatedly trips breakers, runs hot, or shows signs of electrical problems requires immediate professional attention for safety reasons. Motor winding failure, bad capacitors, voltage problems, and inadequate ventilation all cause overheating. Our licensed technicians use proper testing equipment to safely diagnose electrical issues and make repairs that meet code requirements and protect your family.

Motor Failure and Replacement

Complete motor failure is sometimes the most cost-effective time to upgrade to a modern, energy-efficient variable-speed pump that will save you hundreds annually in electricity costs. However, if your existing pump is relatively new or you prefer to maintain your current setup, we can replace just the motor assembly. We'll help you understand all your options and make the choice that best fits your situation and budget.

Why Choose McCool's for Pool Pump Repair

Experienced Licensed Technicians

Our repair technicians aren't general handymen—they're specialists who work on pool equipment every single day. They've repaired thousands of pumps across all major brands including Pentair, Hayward, Jandy, Sta-Rite, and Polaris. This experience means accurate diagnosis, efficient repairs, and solutions that last. When you call McCool's for pump repair, you get true expertise, not guesswork.

Comprehensive Diagnostic Process

We don't just treat symptoms—we identify root causes. Our systematic diagnostic approach examines your entire circulation system, not just the pump itself. We check for plumbing restrictions, air leaks, valve problems, and equipment compatibility issues that might be contributing to your pump problems. This thorough process ensures repairs address the actual problem and prevent recurring issues.

Quality Parts and Proper Repairs

We use manufacturer-approved replacement parts and follow proper repair procedures, not shortcuts. Original equipment seals, genuine capacitors, and quality bearings ensure repairs last. Our technicians have the specialized tools needed for pump work—seal installation tools, impeller wrenches, and proper testing equipment. This professional approach means repairs done right the first time.

Transparent Pricing and Options

Before we proceed with any pump repair, we provide clear explanation of the problem, repair options, and associated costs. We'll discuss whether repair or replacement makes more sense for your situation, including potential energy savings from upgrading to a variable-speed pump. You'll never be surprised by unexpected charges or pressured into unnecessary work.

Same-Day Service Available

We understand that a non-functioning pump is an emergency. Your pool can't operate without circulation, and water quality deteriorates rapidly. That's why we offer same-day pump repair service throughout our Phoenix area service territory when you call early. Our technicians carry common repair parts and can often complete repairs during the initial service call.

Our Pump Repair Process

Initial Diagnosis

We begin by gathering information about your pump's symptoms—when the problem started, what sounds or behaviors you've noticed, and any recent changes to your pool system. Our technician then performs a systematic inspection, checking electrical supply, examining the pump for obvious damage, and testing operation. This initial diagnosis often reveals the problem immediately.

Comprehensive System Assessment

If the issue isn't immediately apparent, we expand our diagnosis to examine your entire circulation system. We check for suction-side air leaks, verify proper valve positions, inspect plumbing for restrictions, and test system components that might be affecting pump operation. This comprehensive approach catches problems that less experienced technicians miss.

Explanation and Recommendation

Once we've identified the problem, we explain exactly what's wrong in terms you can understand, not confusing technical jargon. We discuss your repair options, expected costs, and realistic timelines. If your pump is old or the repair costs are high relative to replacement, we'll discuss whether upgrading makes better financial sense long-term.

Professional Repair Execution

With your approval, our technician completes the repair using proper tools, quality parts, and manufacturer-recommended procedures. We take care to protect surrounding equipment and clean up thoroughly. After repairs are complete, we test operation extensively to verify proper function before considering the job finished.

Follow-Up and Warranty

We stand behind our pump repair work with solid warranties on both parts and labor. We also follow up after repairs to ensure everything continues operating correctly. If any issues arise with our repair work, we return to make it right at no additional charge. This commitment to quality gives you confidence in choosing McCool's.

Preventing Future Pump Problems

Regular Equipment Inspections

Many pump failures can be prevented through regular monitoring and early intervention. Our weekly maintenance service includes thorough pump inspections where we listen for bearing noise, check for leaks, verify proper operation, and catch developing problems before they lead to failure. Customers with our maintenance service experience far fewer emergency pump repairs.

Proper System Operation

Running your pump on appropriate schedules, maintaining clean filters to prevent excessive back-pressure, and keeping baskets clear all extend pump life. We educate our customers on best practices that reduce wear and tear on pumps, helping you get maximum service life from your equipment.

Timely Repairs

When you notice pump problems—unusual sounds, leaks, or performance changes—addressing them promptly prevents minor issues from becoming major failures. A $200 seal replacement now can prevent $1,500 in motor damage later. We encourage customers to report any changes in pump operation so we can investigate before problems escalate.

Consider Variable-Speed Upgrades

If your pump requires major repairs and is more than a few years old, upgrading to a modern variable-speed pump often makes excellent financial sense. These efficient pumps reduce electricity consumption by 50-70%, paying for themselves through energy savings while providing better circulation. We'll calculate the actual payback period for your specific situation.
