Start with the symptom

What's acting up?

Pump is loud or won't prime

Bearings, a shaft seal, or air getting in at the lid or a fitting. Catch it before the motor burns out.

Filter pressure keeps climbing

Loaded cartridge, torn pleat, or a filter that's undersized for the pool. Common after a windy week.

Heater won't fire

Low flow, igniter or flame sensor, high-limit switch, or gas supply. Age and heat exchanger condition decide repair vs. replace.

Salt cell shows low output or "no flow"

Calcium scale on the plates is the usual cause in hard water. Sometimes it's the flow sensor or the cell reaching end of life.

Water level keeps dropping

A pool losing more than the bucket test allows has a leak somewhere: plumbing, light niche, skimmer, or shell. We find it and fix it.

Automation or cleaner acting up

Relays, sensors, and boards on Pentair and Jandy automation; suction, pressure-side, and robotic cleaners.

How a repair goes

Diagnose, quote, fix, test.

Step 01Tell us what's going on

Call, text, or send a repair request with what you're seeing. Even "it's making a noise" helps us bring the right parts.

Step 02Diagnose on site

Pressure, flow, electrical, and a look at the whole pad, not just the part that's complaining. Often one failure is a symptom of another.

Step 03Quote before work

You get the price and the reasoning before anything is replaced. If it's a replace-not-repair situation, we say so and show you the options.

Step 04Fix and test

Repair, run it, and walk you through what was done and what to watch for.

Repair or replace?

How we make the call.

EquipmentUsually repairUsually replace
PumpSeal, lid o-ring, capacitor, or a single bad bearing on a newer pumpBurned motor, or a failed single-speed pump over about 1 HP (California efficiency rules mean the replacement is variable-speed)
FilterCartridge cleaning, o-rings, gauge, air reliefCracked tank, torn or collapsed cartridges, or a filter that's too small for the pool
HeaterIgniter, flame sensor, high-limit, pressure switch on a unit under 10 yearsFailing heat exchanger, corroded burner tray, or a unit past 10 to 12 years
Salt cellAcid cleaning to remove scale; flow sensorPlates worn through at the end of the cell's life
AutomationRelays, sensors, transformerBoard failures on discontinued systems where parts are no longer made

Warranty center

We're an authorized warranty service center for Pentair, Jandy, and Hayward, so a warranty claim comes to our counter instead of a shipping label. Bring the unit or the claim to either store.

What drives the price

  • The part itself (a capacitor vs. a whole motor vs. a new heater)
  • Whether the pad needs re-plumbing or electrical to fit the new part
  • One trip vs. a part we have to order
  • Permits for heater, gas, and electrical work

The part is often already on the shelf at the store, which saves a second trip.

New equipment

Installation, not just repair.

When a part is past saving, or you want to upgrade before it fails, we install new equipment: variable-speed pumps, cartridge and DE filters, gas and heat-pump heaters, salt systems, automation, and robotic or pressure-side cleaners. We sell it at the counter and our own techs install it, not a subbed-out crew.

Automation and salt systems

Pentair and Jandy automation, salt chlorinators, and app control. Installed, programmed, and explained before we leave.

Automatic pool cleaners

Repair on suction, pressure, and robotic cleaners, and new units matched to your pool's shape and debris.

How an install goes

  • We look at the pad, the plumbing, and the electrical, then quote the unit and the install as one number
  • Permits pulled where the city requires them (heaters, gas, electrical)
  • Old equipment hauled off, new equipment plumbed, wired, and pressure-tested
  • Startup and a walkthrough of the settings, plus the manufacturer registration

Commonly asked questions

Do you quote before you do the work?

Yes, every time. We diagnose on site, tell you what's wrong and what it costs to fix, and you decide. Nobody replaces a part without your OK.

My pump is loud. Does that mean it's dead?

Usually not. A screaming or grinding pump is most often a failing bearing or a seal that's let water into the motor. Sometimes it's just air getting in at the lid or a fitting. It's worth looking at before the motor cooks itself.

Should I replace a single-speed pump with a variable-speed?

In California, yes, and in most cases you have to: state efficiency rules mean replacement pool pumps are variable-speed. The good news is they cut the electric bill noticeably, and they're quieter.

Why does my filter pressure keep climbing?

Leaves, dust, algae, and fine debris load the filter, and a Santa Ana wind event can add several PSI overnight. A cartridge that won't come clean or has a torn pleat needs replacing. A DE or sand filter that won't hold pressure after a backwash has its own set of causes we can check.

Why is my heater not firing?

Common causes are low water flow (dirty filter, closed valve), a bad igniter or flame sensor, a tripped high-limit, or gas supply. Heaters over 10 to 12 years old with a failing heat exchanger are usually a replace, not a repair. We'll tell you which.

How do I know if I have a leak or just evaporation?

The bucket test tells you: set a bucket of pool water on a step, mark both levels, and compare after 24 hours with the pump off. If the pool drops faster than the bucket, call us.

Do you work on salt systems and automation?

Yes. Salt cells, flow sensors, control boards, and automation systems like Pentair and Jandy. Hard water scales salt cells, so they need cleaning on a schedule.

Do you install new equipment, or only repair?

Both. Pumps, filters, heaters, salt systems, automation, and cleaners. We sell it at the counter and our own techs install it, quoted as one number.

After spending 2 months trying to fix my pump priming issue on my own, I gave up and called. Scheduling the appointment was easy, and the tech was on time. Gavin saw the issue and fixed it within 15 minutes. Plus, he had the needed parts in his truck. This guy knows his stuff.
