Stress-Free Pool Repairs

Pool troubles? You can rely on us.

Pool Filter Replacement

Keep Your Pool Crystal Clear with Pentair-Backed Expertise
A pool filter is a vital component for maintaining safe, crystal-clear water. Over time, filters typically need replacement every 5 to 7 years to ensure peak performance—and that’s where our Pentair-trained technicians come in.

If it’s been over 6 months since your last filter cleaning, your water looks cloudy, or you’re noticing poor circulation, it’s time to get in touch.

We’ll thoroughly inspect your filter and recommend the best solution—whether it’s a professional cleaning or a Pentair-quality replacement to restore maximum efficiency.

Pool Heater Repair

Extend the Life of Your Pool Heater with Pentair-Certified Care
A pool heater uses natural gas or electricity to warm your pool water—but like any system, it needs regular attention to perform its best. With proper maintenance, a quality Pentair pool heater can last 10 to 15 years.

To protect your investment, we recommend having your heater serviced at least once a year. If you notice reduced efficiency, unusual sounds, or if it stops running altogether, don’t wait—contact our Pentair-trained team for expert diagnostics and repairs.

Pool Pump Repair

A Functioning Pool Pump is Key—Trust Pentair-Certified Expertise
A working pool pump is essential for clean, clear water. If your pump is making noise, leaking, or won’t start, it’s time for a check-up. This includes Pentair variable speed and green motor pumps, which are known for their energy efficiency but still require proper maintenance to stay in peak condition.

Contact us for a quick inspection and expert repair. Whether it’s a simple adjustment or a more involved issue, our Pentair-trained technicians will make sure your pump is circulating water efficiently—keeping your swim space safe, clean, and ready to enjoy.

We do! As a certified Pentair dealer and installer, we sell and install top-rated Pentair pool pumps across California, including the Pentair IntelliFlo3® Variable Speed Pump, Pentair SuperFlo VST, and WhisperFlo VST. Whether you’re in San Clemente, Dana Point, or Laguna Hills, we’ll recommend the best Pentair variable-speed pump based on your plumbing, pool size, and energy-efficiency goals.

Right here! We carry genuine Pentair replacement parts including the Pentair 3-way valve, 2-inch check valves, IntelliValve actuators, and Pentair heater bypass kits.
