Why it happens: Priming failures are almost always an air or suction problem: the pump is pulling air instead of water. Common causes are a low water level (below the skimmer mouth), a clogged skimmer or pump basket, a cracked pump lid or worn lid O-ring letting air in, or a suction-side valve left closed.

Safe checks: top off the water level, empty the skimmer and pump baskets, make sure the pump lid is snug and its O-ring looks smooth, and confirm the valves are open. If it still won't catch prime within a few minutes, shut it off — running dry damages the seal — and call us.

Why it happens: A hum with no spin usually means the motor is trying and failing to turn: a seized shaft after sitting, a failing start capacitor, or debris jamming the impeller. Breaker trips point to an electrical fault or moisture intrusion.

Safe checks: one breaker reset only. If it trips again, leave it off and call — repeated resets on a faulting motor circuit are how small failures become big ones. Motor and capacitor work is a service visit, not a DIY job.

Why it happens: Gas pool heaters need three things: enough water flow, enough gas, and clean ignition components. The most common cause is low water flow from a dirty filter — the pressure switch blocks ignition to protect the heater. Others: a gas supply valve partly closed, air in the gas line after a tank swap, a dirty flame sensor, or restricted airflow around the unit.

Safe checks: clean or backwash your filter, make sure the pump is running on high before the heater calls for heat, and confirm the gas supply valve is open. Leave burner, valve, and sensor work to a professional — gas-side repairs are never DIY.

Why it happens: Short-cycling is usually the heater protecting itself: marginal water flow (dirty filter again, or a pump schedule that drops to low speed mid-heat), a failing pressure sensor, or poor ventilation causing overheating.

Safe checks: run the heater only while the pump is on high speed, clean the filter, and keep the area around the heater clear. If it still cycles, note any error code on the display and call us with it — codes speed up the diagnosis a lot.

Why it happens: Salt cells read low for four common reasons: the water genuinely needs salt, the cell plates are scaled with calcium and need cleaning, the water is cold (below roughly 60°F most cells cut output sharply — normal in a Florida winter), or the flow sensor isn't seeing enough flow.

Safe checks: have your salt level tested (target is on your cell's label, usually ~3,200 ppm) before adding anything — overdosing is harder to fix than underdosing. If salt tests fine, the cell likely needs a scale cleaning or has aged out (cells are consumables, typically 3–7 seasons). We can test the cell directly.

Why it happens: Cloudy or green water is a chemistry-and-filtration problem, not an equipment failure: not enough sanitizer for the heat load, too little daily filter runtime, or a filter that needs cleaning. Florida summers push demand up fast — an afternoon storm plus 90° heat can flip a marginal pool overnight.

Safe checks: test and balance chlorine and pH first, run the filter longer (8–10 hours in summer), and clean the filter. If it doesn't clear in 48 hours, call — persistent cloudiness can also indicate a filtration fault we should look at.

Why it happens: Your filter gauge is a health meter. 8–10 psi above your clean baseline means the filter media is loaded and choking flow. Unusually LOW pressure means water isn't reaching the filter — a clogged skimmer basket, pump basket, or an obstruction on the suction side.

Safe checks: high = clean or backwash the filter; low = empty the baskets. Write your clean baseline pressure on a piece of tape on the tank — it makes every future reading meaningful.

Why it happens: Usually a failed lamp or a tripped GFCI. Flickering can also mean water intrusion past an aging lens gasket — which is exactly the failure you don't want to ignore.

Safe checks: reset the GFCI once. Anything beyond that — lamp, gasket, or wiring — is licensed-electrician territory. Underwater electrical work is never a homeowner job; call us.

Why it happens: Automation controllers occasionally hang after power blips (Florida lightning season is hard on them) or drop off Wi-Fi after a router change.

Safe checks: power-cycle the controller at its breaker for 30 seconds, then re-check the app. If schedules or equipment mapping look scrambled afterward, stop there and call us rather than reprogramming from scratch.

Why it happens: Florida's Residential Swimming Pool Safety Act (Chapter 515, Florida Statutes) requires at least one safety feature — typically a barrier fence, approved door/window alarms, or a compliant safety cover — and federal law (the Virginia Graeme Baker Act) requires anti-entrapment drain covers, which have replacement intervals.

If your pool predates these rules, or you're not sure when the drain covers were last replaced, ask us for a safety check during any service visit — it's quick, and it matters.
