BURST PIPE — Do This Right Now
Turn off water at the main shutoff IMMEDIATELY, then call a plumber. Main shutoff location: at the water meter (near the street in a green/black box) OR at the pressure regulator where the main enters the house. Use a meter key or wrench — clockwise to close. A 1/4-inch burst pipe releases 250 gallons per hour — every minute counts.
FL Insurance: What's Covered
FL homeowners insurance typically covers sudden and accidental pipe burst damage — but NOT gradual leaks or freeze damage from lack of insulation or heating. Document everything before cleanup (photos/video). Call your insurer within 24 hours. Keep all repair receipts.
FL AOB Warning (2023): FL's Assignment of Benefits law (FS 627.7152) changed in 2023 — contractors can no longer have you sign over your insurance claim. Any contractor requesting an AOB form is a serious red flag.
Why FL Pipes Freeze
FL homes are not built for cold weather. Insulation on pipes is minimal/absent, homes lack crawlspace heating, and many pipe runs are in uninsulated exterior walls or attics. When FL temperatures drop below 28F for 4+ hours (2–3 times per decade), uninsulated FL pipes are highly vulnerable. The February 2022 FL cold event caused an estimated $1.5 billion in freeze-related water damage statewide.
5 Highest-Risk Pipe Locations in FL Homes
- Attic Pipe Runs — Many FL homes run supply lines through the attic; attic temps drop below freezing while interior stays warm. Essentially zero freeze protection.
- Exterior Walls (Uninsulated) — FL walls often have little/no cavity insulation; pipe faces full ambient temperature.
- Mobile/Manufactured Home Underbelly — Exposed underbelly pipes in direct contact with outdoor air; 3–5x higher burst rates.
- Outdoor Hose Bibs & Irrigation — Often left connected/active year-round; first to freeze, frequently overlooked.
- Pool Equipment & Outdoor Plumbing — Pool pumps/heaters not freeze-rated; pump freeze costs $800–2,500 to replace.
FL Freeze Timeline — What Happens to Your Pipes
- 32F: Water begins to freeze at pipe wall contact points. No burst risk yet.
- 28F / 4 hrs: Residential pipe freezing begins. Outdoor pipes, hose bibs, attic runs at risk.
- 20F / 6 hrs: High risk — bursts likely in uninsulated homes. Ice block forms, building pressure.
- THAW: THIS is when most pipes burst. Ice fractures the pipe during the freeze; when ice melts, pressurized water escapes through the fracture. Damage often appears hours after temperatures rise — the thaw is the danger zone.
FL Freeze Events History
- January 2010 — Statewide freeze, 10+ days below freezing in North FL.
- December 2022 — Statewide hard freeze, state of emergency, hundreds of millions in damage.
- January 1985 — Historic FL freeze, one of coldest on record.
- December 1989 — Severe cold snap across North/Central FL.
Climate change is NOT eliminating FL cold snaps — the 2022 event was one of the worst in 30 years. Prepare even if you've never experienced a freeze.
What FL Homeowner's Insurance Covers
- COVERED: Sudden and accidental pipe burst (includes freeze burst if home was reasonably heated and pipes reasonably insulated).
- COVERED: Water damage from the burst (drywall, flooring, personal property, subject to deductible).
- NOT COVERED: Gradual leaks (classified as lack of maintenance).
- NOT COVERED: Flood damage (requires separate NFIP/flood policy).
- DISPUTED: Freeze damage where pipes were completely uninsulated or home left without heat — document insulation and thermostat settings.
Mobile Home Freeze Specifics
Mobile/manufactured homes have 3–5x higher burst rates during FL freezes. Risk factors: exposed belly wrap with no insulation, no crawlspace heating, polybutylene pipe (more brittle when frozen), thin vinyl skirting that doesn't stop cold air circulating under the home.
Water Meter Key — Every FL Homeowner Needs One
The water meter shutoff requires a meter key (curb key) — a T-shaped tool. Most FL meters are buried near the street in a green/black plastic box. Without this key you cannot shut off water at the street. Cost: $8–15 at any hardware store. Buy one now and test your shutoff before you need it. During a major freeze, emergency plumbers are booked for days — shutting off your own water buys critical time and prevents tens of thousands in additional damage.
