Equipment

Understand controllers, sensors, pH probe calibration, freeze protection logic, and where ORP guidance breaks down in cyanurated pools.

Map how feeders, probes, ORP, pump schedules, and interlocks interact so automation does not quietly create chemistry failures.

Run erosion feeders, liquid pumps, acid tanks, and injection hardware as calibrated chemical systems with real compatibility and leak risks.

Compare liquid chlorine, SWGs, tablets, and supplemental systems without pretending any of them are “chemical free.”

Compare suction, pressure-side, robotic, and in-floor cleaners by hydraulic load, debris profile, and maintenance burden.

Use construction-phase decisions to reduce future chemistry drift, debris load, and hydraulic headaches.

Label valves, breakers, shutoffs, drain points, and manual-safe positions so seasonal work and service calls start from facts.

Prioritize pumps, filtration, test gear, and safety basics before you spend money on convenience upgrades.

A canonical guide to sand, cartridge, and DE filters; clean baseline pressure; backwashing; and cloudy-water filtration fixes.

Map Pentair, Hayward, Jandy, Raypak, AquaCal, Paramount, Polaris, Dolphin, and similar families before you trust any equipment guidance.

Map who actually controls pump start, heater enable, valves, chlorination, and freeze response when the equipment pad mixes brands or generations.

Use covers intentionally for evaporation control, heat retention, debris management, and safety instead of treating every cover as interchangeable.

Run gas heaters, heat pumps, and solar heating with the right expectations for flow, climate, covers, and service boundaries.

Understand flow, head loss, speed control, priming, and filter matching before you trust generic runtime folklore.

Run an SWG by the manual, manage stabilizer and scale, and separate salt-level problems from production problems.

Understand spillover logic, valve modes, hotter-water chemistry, and shared-equipment troubleshooting for combined pool/spa systems.

Understand the limits of UV, ozone, mineral, and similar add-ons so they do not displace basic sanitizer and testing discipline.

Spillovers, laminars, fountains, bubblers, and deck jets affect pH drift, evaporation, scale pressure, and scheduling.
