The headline rule: never drain your pool before a hurricane. South Florida's water table sits high enough that an empty pool can hydrostatically "pop" — the groundwater pressure under the shell exceeds the weight holding it down, and the entire pool lifts off its base. Repair runs $20,000–$50,000 minimum. Both the Florida Department of Emergency Management and the Florida Swimming Pool Association explicitly warn against draining.
What you do instead: lower the water level 12 inches below the skimmer to absorb storm rainfall, shock the chlorine to a 5–7-day reserve, and bag your pump motor.
The 72-hour countdown
South Florida's NWS cone of probability typically stabilizes 72 hours before landfall. That's your trigger to start.
72 hours out: equipment audit + supply check
- Pump bearings — listen for whining or rumble.
- Heater pilot/igniter test (gas or heat-pump).
- Automation firmware up to date.
- Pressure gauge baseline recorded (8–12 psi cartridge, 10–15 psi DE).
- Stock 2–3 gallons of liquid chlorine and a quart of phosphate remover.
- Photo-document pool, deck, and equipment for insurance.
48 hours out: lower water and shock
Lower the water level 12 inches below the skimmer:
- Sand/DE filter: Set the multiport valve to "waste" and run the pump until level drops.
- Cartridge filter: Use a submersible pump or attach a hose to the pump's drain plug.
Then shock to 10 ppm free chlorine — roughly 3× the normal target. This buys you 5–7 days of sanitization while the pump is offline. Balance pH to 7.4 to keep the chlorine effective.
24 hours out: secure the deck and bag the equipment
- Remove every loose item: patio furniture, umbrellas, pool toys, floats, planters, grills, hoses. Anything not bolted down can become a missile.
- Turn off breakers: pump, heater, lights, SWG, automation.
- Bag the pump and motor with contractor-grade garbage bags + duct tape. Cover the heater intake and exhaust.
- For Cat 3+ forecasts, unscrew the pump motor and store it indoors. Replacement motors run $400–$900 — far more than the 30 minutes of disconnect time.
During the storm: stay out
Do not enter the pool area during the storm. The 10 ppm chlorine shock holds sanitization for 5–7 days even with no circulation. Falling tree limbs, downed power lines, and wind-borne debris are the real risks; the pool itself is fine.
Post-storm recovery sequence
Within 24 hours: skim and document
- Skim floating debris before it sinks (sunken debris stains plaster).
- Photo-document any damage before cleanup, for insurance.
- Check skimmer and pump baskets — empty, inspect for cracks. Don't restart the pump yet.
48–72 hours: manual vacuum + restart
- Set the multiport to "waste" and manually vacuum heavy debris. This bypasses the filter and dumps debris-laden water out the backwash line — saves your filter from a tear-down.
- Restart the pump after visible debris is cleared.
- Shock to 5 ppm.
- Rebalance pH (7.2–7.6) and alkalinity (80–120 ppm).
- Backwash the filter once water clears.
If algae bloomed: green-to-clean recovery
If your shock didn't hold or the outage exceeded 5 days, expect algae. Triple-shock to 15 ppm, brush daily, and run the filter 24 hours/day for 3–7 days. Severe blooms may need a phosphate remover and a full filter tear-down. See our green-pool recovery guide for the full protocol.
Insurance documentation checklist
Most South Florida HO-3 policies cover wind, debris, and falling- tree damage to the pool structure and equipment — but only if you can prove pre-storm condition. Pre-storm photo set:
- Pool from each side, water level visible.
- Each piece of equipment with serial number readable.
- Surrounding deck, coping, screen enclosure.
- Any pre-existing damage (file with claim if disputed).
Flood damage is excluded from standard HO-3 — you need separate flood insurance for that. Confirm specifics with your carrier before storm season.
Local providers with named hurricane-prep service
Of the 13 primary companies in the 2026 Boca/Delray ranking, two publish dedicated hurricane-prep service tiers:
- Florida's Best Pools — pre-storm prep included for weekly customers; post-storm green-to-clean recovery available as add-on.
- So Flow Pool Services — explicit "hurricane preparation" SKU listed in standard services.
Frequently asked questions
No — never fully drain a pool in South Florida before a hurricane. The high water table can hydrostatically lift an empty pool shell (called 'popping the pool'), causing $20,000–$50,000 of damage. Lower the water level only 12 inches below the skimmer to make room for rainfall. Florida's Department of Emergency Management and the Florida Swimming Pool Association both publish this guidance.
Begin 48–72 hours before projected landfall, which is when the cone of probability stabilizes. Phase the work: 72 hours out — equipment audit, chemistry; 48 hours out — lower water, shock, secure deck items; 24 hours out — bag pump, turn off breakers; 12 hours out — final walk-through and photo documentation for insurance.
Yes. Turn off the breaker for the pump, heater, lights, and SWG before the storm arrives. Power surges and floodwater destroy pump motors. If a Cat 3+ is forecast, unscrew the pump motor and store it indoors. Bag the housing with garbage bags and tape to keep debris out.
Free chlorine 10 ppm (3× normal); pH 7.4; total alkalinity 80–120. The high chlorine reserve buys you 5–7 days of sanitization while you can't run the pump. After the storm, recover by skimming heavy debris, manually vacuuming, then shocking to 5 ppm and rebalancing.
Sequence matters. (1) Skim debris before it sinks. (2) Manually vacuum heavy debris — don't try to filter it. (3) Empty skimmer and pump baskets, check for cracks. (4) Restart the pump only after visible debris is cleared. (5) Shock to 5 ppm. (6) Rebalance pH (7.2–7.6) and alkalinity (80–120 ppm). (7) If algae bloomed during the outage, plan a green-to-clean recovery (3–7 days).
Most South Florida HO-3 policies cover the pool structure under the dwelling extension and equipment under personal property — but only if you can document pre-storm condition. Photo-document equipment serial numbers, water level, and surrounding deck before the storm. Wind-borne debris damage and falling-tree damage are typically covered; flood damage requires separate flood insurance. Confirm with your specific carrier.
