Pool Equipment Repair
Repair for pool pumps, filters, heaters, and motors in East Honolulu. Honest diagnosis and solid repairs from Paul Costello, who has worked on pool equipment since 2000.
When your pump goes quiet on a Saturday morning or the heater won’t fire before a family party, the clock starts. In Hawaii Kai and across East Honolulu, a pool without circulation can go cloudy in a day and green in two. So pool equipment repair in Hawaii Kai has to be fast and it has to be right. Koko Head Pool Service has been fixing East Honolulu pool equipment since 1995, and Paul Costello has been doing it himself since 2000.
Every Piece of Equipment, Diagnosed and Repaired
A pool system is dozens of mechanical, electrical, and plumbing parts that have to work together. When one fails, it can take other parts down with it or wreck your water quality. Paul is a Certified Pool Operator (CPO) and has been diagnosing and repairing pool equipment since 2000. He’s seen these systems fail in just about every way they can.
Equipment We Service
- Pumps and motors: single-speed, dual-speed, and variable-speed units
- Filters: cartridge, sand, and diatomaceous earth (DE) systems

Brands We Service
We work on Pentair, Hayward, Jandy, Sta-Rite, and nearly every other brand you’ll find in Hawaii’s residential and commercial pools. If it has a name badge, we’ve probably had it apart before.
Warning Signs Your Equipment Needs Attention
Pool equipment rarely dies without warning. Catch these early and you’re often looking at a small repair instead of a full replacement:
- Unusual pump noises: grinding, screeching, or loud humming from the motor
- Reduced water flow: weak return jets or sluggish skimmer suction
- Air bubbles in the pump basket: usually a suction-side leak or a failing shaft seal
- Cloudy water despite proper chemistry: often a filter problem
- Heater not igniting or cutting out: could be the igniter, pressure switch, or heat exchanger
- Error codes on automation panels: sensor failures, communication faults, or flow issues
- Tripping breakers: a serious sign of electrical trouble in the motor or wiring
- Visible leaks: water pooling around the pump, filter, or plumbing connections
A small problem left alone almost always turns into a bigger bill. Call us at 808-399-4388 when you first notice something off.
How We Handle Every Repair
Step 1: Thorough Diagnosis
We start by listening, to you and to the equipment. Then we look at the whole system, not only the part you called about, because one failure often points to a second one on the way. We test electrical connections, measure flow, check pressures, and track down the actual cause.
Step 2: Honest Assessment
Once we know what’s wrong, we tell you in plain language: what failed, what it costs to fix, and what we’d do if it were our pool. We don’t push work you don’t need.
Step 3: Quality Repair
We use manufacturer-grade parts, not cheap aftermarket pieces that fail again in six months. Most repairs get done on-site, and we run the whole system before we leave to make sure it’s working.
Step 4: Prevention Advice
Before we go, we point out anything else we noticed (worn bearings, aging seals, corroded connections) so you can plan for it instead of getting surprised by another breakdown.
“It turned out cyanuric acid was too high and our sand filter was too small. He gave us a quote in a few hours. Paul came back in a couple of days to install the new filter with glass filtering media. Paul was knowledgeable, professional and friendly. The cost was reasonable.”

Repair vs. Replace: We Give It to You Straight
We’ll tell you when a repair is the smarter move, even when a replacement would be a bigger job for us.
Our general guideline:
- Repair when the equipment is under 8 years old, the repair costs well under half of a replacement, and the unit has been maintained.
- Replace when the equipment is aging, repair bills keep climbing, a newer model would cut your electric bill noticeably, or parts aren’t available anymore.
- Upgrade when a failure opens the door. A burned-out single-speed pump, for example, is a good excuse to put in a variable-speed model that pays for itself in electricity savings within two to three years.
We walk you through the numbers and you decide. No pressure and no upsell. We’ve been a family business in this community since 1995, and we plan to be here a lot longer.
Why Hawaii Is Brutal on Pool Equipment
Mainland pool equipment might last 10 to 15 years. In East Honolulu, you’re doing well to get 8 to 10 out of some parts. Here’s why:
Salt air corrosion. Even without a saltwater pool, the ocean air in Portlock, Kahala, and Diamond Head goes after metal housings, electrical terminals, and circuit boards every day. Corrosion kills more pool equipment in our area than anything else.
Year-round operation. There’s no winter shutdown here. Your pump, filter, and heater run twelve months a year and pile up hours much faster than mainland equipment. More hours means more wear on bearings, seals, capacitors, and impellers.
Humidity and moisture. Constant humidity breaks down electrical insulation, grows mold inside control panels, and hardens rubber gaskets and O-rings.
Hard water and mineral buildup. Oahu water can run high in calcium, which leaves scale inside heater heat exchangers, salt cells, and filter parts.
Paul has spent 26 years learning how these conditions wear down each piece of equipment. That’s why his diagnoses are faster, his parts choices hold up better, and his repairs are built for our weather, not for a mainland training manual.
“The tech came promptly after my call and diagnosed a blown fuse. I was back up in about 15 minutes. Will definitely be using Koko Head Pool Service for my next repair.”

What customers say about Koko Head Pool Service
Paul promptly arrived at my residence within 30 minutes of my call to assist me with troubleshooting an issue. Subsequently, he replaced a part on the filter on the same day, providing exceptional service and demonstrating his professionalism. I am confident that he will be the preferred provider for all my future pool maintenance needs. His service is truly exceptional, and a five-star rating does not adequately reflect his capabilities.
My wife has been maintaining our pool for a year. Lately it keeps getting greener and greener. She kept brushing, cleaning filters, back washing and using more shock, algicide etc but all to no avail. Based on the reviews I read I called Paul of Koko Head Pool Service. He came out the same day to inspect our system. It turned out cyanuric acid was too high and our sand filter was too small. He gave us a quote in a few hours. We drained and refilled the pool. Paul came back in a couple of days to install the new filter with glass filtering media. Paul was knowledgeable, professional and friendly. The cost was reasonable. Now the wife is happy and I am happy too. 6 Stars to Paul if there is such thing.
We lived in Hawaii Kai for many years, and have a gorgeous pool in Portlock. Went through many so-called "Professional Pool Cleaners" over the years… Some were okay, a couple were good, but most ABSOLUTELY sucked. As a Commercial & Residential Property Manager, I need the BEST for my clients. KOKO HEAD POOL SERVICE has been by far SPECTACULAR when it comes to QUALITY, PUNCTUALITY, KNOWLEDGE OF VARIOUS POOL SYSTEMS, EMERGENCY FAIR PRICING &, PROFESSIONALISM. Specifically PAUL COSTELLO. He and his Crew handles many of my clients, but Paul in particular is hands down favorite of them all.

Frequently Asked Questions
How quickly can you respond to an equipment breakdown?
A dead pump or no circulation goes to the front of the line, and we try to get out the same day or the next. In Hawaii's heat, a pool without circulation can start turning green within 48 hours, so we don't sit on those calls. Non-urgent repairs get scheduled at a time that works for you, usually within a few days.
Do you work on all pool equipment brands?
Yes. We work on Pentair, Hayward, Jandy, Sta-Rite, and the other brands you'll find on Oahu equipment pads. Paul has been repairing pool equipment across East Honolulu since 2000, so there isn't much he hasn't had apart. If it runs your pool, we can diagnose it and fix it.
How do I know if my pool equipment should be repaired or replaced?
We look at the equipment's age, the repair cost, how efficient it is, and how much life it has left. A rough rule: if the repair costs more than half of a replacement and the unit is 8 to 10 years old or older, replacing it usually makes more sense. We'll explain why we're recommending what we are, and you make the call.
What happens if a repair doesn't hold?
Replacement parts carry the manufacturer's warranty, and we'll help you with that process if a part fails. If something we repaired isn't working right, call Paul at 808-399-4388 and tell him. We use quality parts and do the job carefully so it holds the first time, and we'd rather hear about a problem than have you live with it.
How does living near the ocean affect my pool equipment?
Salt air is the biggest threat to pool equipment in East Honolulu. It eats electrical connections, metal housings, and circuit boards much faster than you'd see inland. Homes closest to the water, like Portlock and Diamond Head, get hit hardest. And with no off-season, your equipment logs far more hours than a mainland pool's, so parts wear out sooner.
What are signs that my pool pump is failing?
Grinding, screeching, or humming from the motor. Weak flow from the return jets. The pump losing prime and sucking air. Water leaking around the housing or shaft seal. A motor that's hot to the touch or keeps tripping the breaker. Call us when you notice any of these, before the pump quits completely. Catching it early usually means a cheaper repair.
Can you upgrade my equipment during a repair visit?
Yes, and a repair visit is a good time to talk about it because we're already looking at your whole system. When an old single-speed motor dies, a lot of homeowners switch to a variable-speed pump and save hundreds a year on electricity. We can also talk through automation, a better filter, or a salt chlorine generator on the same visit.
