A market guide for independent insurance agents. Last reviewed: June 2026.
Polybutylene (installed ~1978-1995) is one of the most common 4-point inspection failures in the country, and most admitted carriers respond one of three ways: decline, write with a full water-damage exclusion, or apply a water sublimit (commonly $10,000) after a plumbing inspection. Florida's Citizens illustrates the math: poly is acceptable only on homes 20 years old or newer — and since virtually all poly went in before 1995, nearly every poly home fails that test.
Four working routes for agents: (1) bind-subject-to-repipe — many carriers will issue conditioned on full PEX/copper replacement within 30-60 days; (2) accept the water exclusion/sublimit and document the client's informed consent; (3) E&S homeowners through your wholesaler's personal-lines desk (Lloyd's is the largest surplus-lines home insurer in the US) — mind state diligent-search rules; (4) FAIR plan + DIC pairing, remembering most FAIR plans exclude water damage, liability, and theft entirely.

| Market / Program | Type | How Agents Access It | Notes |
|---|---|---|---|
| Bind-subject-to-repipe (various admitted) | Admitted | Standard markets | Full repipe within 30-60 days as a binding condition — the cleanest outcome when the client will invest. |
| Admitted with water exclusion / $10K sublimit | Admitted | Carrier-by-carrier | Common compromise after plumbing inspection. Document informed consent — the exclusion guts the most likely claim. |
| E&S homeowners (Lloyd's et al.) | Non-admitted | Wholesaler personal-lines desks (TAPCO, Burns & Wilcox, etc.) | The classic poly fallback. Diligent-search/declination rules apply (e.g., NY requires 3 admitted declinations). |
| FAIR plan + DIC policy | Residual market | Direct / agent | FAIR covers fire-centric perils; most exclude water, liability, theft — pair with a DIC to fill gaps. |
| Citizens (FL) — reference point | Residual (FL) | FL agents | Poly acceptable only on homes 20 years or newer with no leak history; 4-point required on 20+ year homes (forms updated July 2025). |

Rarely without conditions. The realistic outcomes are bind-subject-to-repipe, a water-damage exclusion or sublimit, or E&S placement. Some carriers accept 'sudden and accidental' poly losses only — verify in writing.
A whole-home PEX repipe typically runs $4,000-$15,000 depending on size and region — often less than years of E&S premium differential plus an uncovered water loss.
Only partially. FAIR plans cover fire-centric named perils and most exclude water damage entirely, plus liability and theft — pair with a DIC policy and explain the residual gaps.
