Salt chlorination systems are popular across San Jose because they reduce the handling of liquid or granular chlorine and, when working correctly, produce a softer-feeling water that most swimmers prefer. But they do fail in predictable ways. The most common issue isn't a dead cell—it's a cell that's scaled over and running at a fraction of its rated output. Calcium and mineral deposits coat the titanium plates and choke chlorine production without triggering an obvious error, so the pool slowly drifts toward low sanitizer while the system appears to be running fine. The result is hazy water or algae that the homeowner assumes is a chemistry problem rather than an equipment problem.
Before any replacement gets quoted, the cell gets tested. Output is measured, plate condition is inspected, and if scaling is the culprit, a proper acid bath often restores the cell to serviceable condition without the cost of a new unit. When replacement is genuinely necessary, K&D Quality installs Pentair IntelliChlor, Hayward AquaRite, Jandy AquaPure, and CircuPool systems, sized appropriately for the pool volume, and the installation includes the cell, control board, flow switch, and plumbing connections. Salt level, stabilizer, and pH are dialed in at startup because a salt system runs correctly only inside a specific chemistry window.
Salt chlorination in the South Bay comes with a specific challenge: San Jose's municipal water is moderately hard, and that calcium doesn't disappear when you switch from chlorine. Cell scaling happens faster in hard-water environments, and the difference between a cell that lasts its full service life and one that fails early is mostly maintenance discipline. Homeowners who've had a salt system installed by K&D Quality and keep it on a regular service schedule find the system delivers on its promise—consistent chlorine production, less manual dosing, and water that feels noticeably different than a traditionally chlorinated pool.

Full-service weekly maintenance on a fixed route day. Includes brushing walls and tile line, vacuuming as needed, skimmer and pump basket emptying, filter pressure check, water testing for chlorine, pH, alkalinity, cyanuric acid, and salt, and chemical balancing. Equipment is visually inspected every visit and you get a text or email if anything's off. Same tech every week, never subcontracted. Most San Jose pools fall between $165 and $235 per month depending on size and tree cover.
Diagnosis and repair on every major brand: Pentair, Hayward, Polaris, Jandy, Sta-Rite, Zodiac, Raypak. Pumps, motors, filters, valves, plumbing, timers, pressure switches, unions, and o-rings. The parts that fail first ride on our truck, so most repairs close in a single visit. We tell you what's worth fixing and what's worth replacing, with the actual cost difference in writing before any work starts.
Full pool resurfacing for plaster pools showing stains, rough spots, hollow areas, or 15-plus years of wear, and fiberglass refinishing for gel-coat fading and osmotic blisters. Process includes drain, chip-out or prep, bond coat, new plaster or gel coat, fill and start-up chemistry over the first 28 days. Typical residential job runs 7 to 10 working days plus fill time. We coordinate the whole job, no separate contractors to chase.
Service and repair on attached spas and standalone hot tubs. Heater diagnosis, circulation pump replacement, jet repair, control pack swaps, cover lifter installs, and full drain-and-refills with line flush. We work on Sundance, Hot Spring, Caldera, Jacuzzi, and most older builder-grade attached spas. If the spa shares equipment with the pool, we already know the plumbing. Most diagnostic visits run under an hour and end with a clear written quote.
Gas heater and heat pump repair on Raypak, Pentair MasterTemp, Hayward Universal H-Series, and Jandy LXi and JXi. Common fixes: ignition control modules, pressure switches, gas valves, thermal regulators, heat exchangers. We also install replacement heaters and run new gas lines through licensed sub when needed. Cold pool the week before a party? We carry the most-failed parts and most repairs finish same day. Full replacement installs run 1 to 2 days.
Install, program, and repair pool automation: Pentair IntelliCenter and EasyTouch, Hayward OmniLogic and OmniHub, Jandy AquaLink and iAquaLink. We set up the app on your phone, label every relay, and walk you through schedules for pump speeds, heater, lights, and salt cell. Existing system glitching? Most issues trace to a failed actuator, a stuck relay, or a wifi gateway that needs reflashing, not a full board replacement. We diagnose before we sell.
