FL Hurricane Plumbing Prep
Protect your home. Know your risk. Get ready. CFC Licensed Plumbers.
FL Law You Should Know
FS 553.73 requires flood-resistant construction standards. A building permit is required for all post-storm plumbing repairs. Insurers require documented pre-storm shutoff to validate water damage claims — photograph your shutoff before the storm.
Pre-Storm Plumber Visit Recommendation
A licensed CFC plumber pre-storm inspection costs $150–$300 and covers: water heater anode rod, all shutoff valves, sump pump condition (if any), outdoor hose bibs & irrigation. Book at least 72h before predicted landfall.
5 FL Hurricane Plumbing Facts
- Florida averages 1.6 hurricane landfalls per year — the highest rate of any U.S. state. The Gulf and Atlantic coasts face completely different storm tracks.
- Storm surge and prolonged heavy rain flood septic systems and contaminate private well water, often requiring weeks of remediation and professional testing before water is safe to drink.
- Post-storm water main breaks cause citywide boil-water notices. This happened across dozens of FL municipalities during Hurricane Ian (2022) and Idalia (2023), affecting hundreds of thousands of residents.
- Galvanized steel and polybutylene pipes (common in homes built before 1995) are the most vulnerable to storm pressure surges and post-flood oxidation. Repiping with PEX is the long-term solution.
- FL homeowner's insurance typically excludes flood damage. A separate NFIP (National Flood Insurance Program) policy is required and must be purchased at least 30 days before any storm event.

Electrocution Warning — Read This
DO NOT turn on a flooded electric water heater — the risk of electrocution is severe. Call a licensed FL plumber with a valid CFC license number before restoring power to any water heater, pump, or appliance that experienced any flood or submersion contact.

FL DEP Boil-Water Notices
Check floridadep.gov and your county emergency management website immediately after any storm. Well owners must perform a bacteriological water test before drinking — do not rely on visual inspection. Shock chlorination kits ($15–30) should be on-hand before the storm season begins.

FL Building Permit Requirement
Post-storm plumbing repairs over $2,500 typically require a Florida building permit. Emergency permits are available within 48 hours of a declared disaster under FS 489.117. Ask your contractor to pull permits — unpermitted repairs can void insurance claims and complicate future home sales.
