FL Repipe by the Numbers: 4 FL-approved materials; $4–14 per LF installed (FL avg); 50yr+ for copper in FL climate; FPC 2023 §604 material code.
Copper Pipe (Type L — FL Preferred)
Cost installed $9–14/LF (Type L). FL Lifespan 50+ years — longest track record. FL Code: FPC 2023 §604.1 — Type K/L/M all approved. Insurance: strongly preferred by Citizens, State Farm, Allstate, Universal; many carriers offer lower premiums. FL Concern: pinhole leaks in aggressive soil or acidic water (Miami-Dade, Broward, Charlotte); Type L over Type M in South FL; request water chemistry report. Pros: 50+ year proven lifespan, insurance preferred, best resale boost, no UV restrictions. Cons: highest upfront cost, pinhole leak risk, rigid/harder to route, can corrode in sandy soil, price tied to copper market.
PEX-A Pipe (Uponor / Rehau) — Premium Flexible
Cost installed $5–9/LF. FL Lifespan 25–50 years projected (FL-approved since 2003). FL Code: FPC §604.3 — ASTM F876/F877, NSF 61 required. Insurance: accepted by Citizens and most FL carriers. Key feature: expansion fittings, no crimp rings; most flexible PEX (heat gun fixes kinks); best freeze resistance (North FL benefit); must be sleeved from UV outdoors. FL Code Note: 18 inches of copper pipe required adjacent to each water heater connection (FPC §604.3) — applies to all PEX types. Pros: best freeze resistance, most flexible routing, no corrosion, self-heals kinks, cost-effective. Cons: not for UV, chlorine may degrade over decades, some lenders still flag PEX, requires copper at WH stub, projected (not 50-yr proven).
PEX-B Pipe (SharkBite / Viega / Watts) — Standard Flexible
Cost installed $4–8/LF. FL Lifespan 25–50 years projected. FL Code: FPC §604.3 — ASTM F876, NSF 61. Insurance: widely accepted; most common PEX in FL repipes since 2008. Key feature: crimp/clamp fittings (simpler tooling); stiffer than PEX-A but flexible enough; cannot self-heal kinks; SharkBite push-to-connect popular for repairs (not recommended in-wall long-term). Pros: lowest price, most FL plumbers know it, widely available, no corrosion, insurance accepted. Cons: stiffer than PEX-A, cannot fix kinks, not for UV, projected lifespan only, crimp tools required.
CPVC Pipe (FlowGuard Gold) — Use with Caution
Cost installed $5–9/LF. FL Lifespan 25–40 years — FL heat/humidity accelerate brittleness. FL Code: FPC §604.2 — ASTM D2846, NSF 61, but aging concerns apply. Insurance: Citizens and several FL carriers now flag CPVC 15+ years old; some require inspection or surcharges. FL Concern: brittle in heat/UV/chemical interactions (some cleaning products cause stress cracking); 2007 Lubrizol/BF Goodrich class action involved certain formulations; falling out of favor for whole-house repipes; only use current FlowGuard Gold. Pros: hot-water rated (180°F), high pressure rating, no chlorine degradation, rigid like copper. Cons: brittle over time in FL heat, growing insurance issues, recall history, incompatible with PVC cement, falling out of FL market.

*Copper pinhole risk higher in South FL with acidic water (pH < 7.0) or sandy soil (Miami-Dade, Broward, Charlotte). Test water before choosing copper.
What Drives Repipe Cost in FL
Home size/linear footage (primary driver); material choice (±30–60% of total); slab-on-grade access cuts (+$1,200–2,500); number of bathrooms (+$300–700 each); drywall patching ($600–3,500); permit fees ($75–450); water heater reconnection ($150–450); fixture reconnect ($35–85 per fixture).
FL pro tip: Most FL plumbers prefer PEX-B for everyday repiping — saves 35–50% vs. copper while meeting code. Copper is worth the premium if selling or if your insurer offers a significant discount. Get 3 bids from licensed CFC plumbers.

FL Homeowner Insurance Guidance
- Citizens: Copper preferred; PEX accepted; CPVC 15+ years requires inspection — may be rated 'inferior plumbing.'
- State Farm: Copper strongly preferred; PEX widely accepted; CPVC case-by-case.
- Allstate (FL): All three accepted; possible surcharge on CPVC homes built before 2000; PEX increasingly preferred.
- Universal Property & Casualty: Copper most preferred; PEX accepted since 2012; CPVC triggers additional underwriting review.
- Several FL surplus lines carriers added CPVC exclusions in 2022–2025 policies. Get a letter from your plumber documenting material/brand/date; some insurers offer 5–15% premium reduction for copper or new PEX repipe.
