Between June 1 and November 30, tropical depressions, storm surges, and hurricanes pose recurring threats to residential properties across the Atlantic coast of Florida. While homeowners dutifully board windows and secure lawn furniture, swimming pools are often subjected to dangerous misconceptions that result in catastrophic structural damage or ruined electrical equipment.
The Cardinal Rule: Never Drain a Florida Pool
The single most destructive mistake a pool owner can make ahead of an approaching hurricane is attempting to drain the pool to prevent overflow. South Florida’s geography consists of a high water table resting on porous limestone. During prolonged tropical rains, the soil surrounding your swimming pool becomes fully saturated with heavy groundwater.
An in-ground swimming pool acts like a hollow concrete ship. When full, the 20,000 to 30,000 gallons of water provide 160,000 to 240,000 pounds of downward ballast. If the water is drained, external hydrostatic pressure from the waterlogged soil easily overcomes the weight of the concrete shell, popping the pool out of the ground like a cork. This fractures underground plumbing, buckles surrounding travertine decks, and permanently destroys the structural foundation of the pool. Experienced technicians recommend lowering the water level by no more than 12 to 18 inches—just enough to accommodate torrential rain without exposing the skimmer throat or drying out the plaster.
Securing the Equipment Pad Before Landfall
High winds, flying debris, and electrical surges are the primary destroyers of pool pumps, chlorinators, and automated valves during tropical weather systems. Follow this checklist 24 to 36 hours before anticipated landfall:
- Kill Main Breakers: Turn off electrical circuit breakers at the main service panel feeding the pool sub-panel. Never leave pumps or heat pumps energized during grid brownouts or lightning storms.
- Wrap Exposed Motors: If the equipment pad sits in a low-lying zone prone to standing water or canal overflow, wrap pump motors securely in heavy-duty waterproof tarps secured with bungee cords, or disconnect the motor entirely and store it indoors.
- Store Loose Patio Furniture: Never throw patio chairs, umbrellas, or tables into the swimming pool. Metal frames corrode, while sharp fiberglass corners can gouge plaster and tear vinyl liners under wind-churned water. Store all outdoor items inside a garage or screened lanai.
- Preemptive Shock Treatment: Dose the pool with a double ration of liquid chlorine and concentrated algaecide 24 hours before the storm hits. With power outages frequently lasting days, this chemical barrier prevents green algae from blooming while circulation is offline.
Post-Storm Recovery Protocol
Once local authorities confirm that conditions are safe, survey the equipment pad before restoring power. If the pump motor was submerged under standing water, do not flip the breaker back on; doing so will short the stator windings and ruin the unit. Allow the motor to dry completely, or have a certified route technician inspect the internal insulation with an ohmmeter. Skim out large palm fronds and branches manually with a rake or net before running filtration to keep skimmer lines free from blockages.
