FL Plumbing Pre-Sale Home Inspection Prep

What Is a Florida 4-Point Inspection?

Insurance companies (primarily Citizens Insurance) require a 4-point inspection for homes 25+ years old (some at 30). It covers Electrical, HVAC, Plumbing, and Roof. The plumbing section notes supply pipe material, drain pipe material, water heater age/condition, visible leaks, active corrosion, and unpermitted modifications. Polybutylene supply pipe and cast iron drain in active failure are the two most common reasons Citizens denies or cancels a policy.

Plumbing Issue 4-Point Result Insurance Impact
Polybutylene supply pipe Fail — flagged Policy denial or non-renewal
Galvanized supply (active corrosion) Fail — flagged Surcharge or denial
Cast iron drain (cracked/failing) Fail — flagged Required repair within 30 days
Water heater >10 years Noted — not fail Surcharge; >15 yrs = possible denial
Active leak at supply/drain Fail — flagged Policy suspended until repaired
Copper supply (good condition) Pass No surcharge
PVC drain (good condition) Pass No surcharge
PEX supply (permitted) Pass No surcharge
Missing P-trap under sink Noted No insurance impact but buyer concern
No water shutoff at fixtures Noted No insurance impact but noted

Deal-Killing Plumbing Defects in Florida

  • Polybutylene Supply Pipe (DEAL KILLER): Gray flexible plastic installed ~1978–1995 (Quest, Vanguard, Qest). Reacts with chlorine, becomes brittle, cracks from inside. Citizens and most private FL insurers will not insure homes with poly — uninsurable until repipe. Cox v. Shell class action (1995) fund is exhausted. Solution: full repipe to PEX/CPVC, $3,500–$7,500 for a 3/2.
  • Galvanized Steel (Corroded) (MAJOR): Standard until ~1970. Reacts with FL's mineral water, rust reduces flow, pinhole leaks. Low pressure, rust staining, orange water. Active corrosion can trigger Citizens denial or surcharge ($500–$1,500/yr). Solution: repipe to copper/PEX, $4,000–$9,000.
  • Cast Iron Drain Failure (MAJOR): Used pre-~1975. FL's acidic soil/humidity accelerate corrosion; scaling, pitting, cracks, collapse after 40–50 yrs. Camera inspection ($300–$500). Citizens added cast iron condition to 4-point in 2022. Solution: trenchless liner $2,500–$5,000 or full repipe $6,000–$18,000.
  • Missing or Dry P-Traps (COMMON): Block sewer gases. Missing traps violate FPC 404. Dry traps common in unused guest baths/vacation homes (run water 30 sec). Solution: install P-traps, $150–$600.
  • Water Heater Age & Condition (COMMON): 4-point asks age/condition. Citizens: 10–15 yrs may surcharge; over 15 yrs many require replacement. FL hard water reduces lifespan. Hot water lines under slab are a slab leak risk. Solution: replace before listing, $900–$1,800.
  • Unpermitted Plumbing Work (IMPORTANT): Title companies/attorneys search permit records. Unpermitted additions/conversions/relocations must be disclosed or remediated. Title may require close-out inspection or as-built. Can void insurance. Solution: after-the-fact permit + inspection, $500–$2,000.

Pro tip: Pull permit history before listing — open permits found by your own search can be closed on your timeline; ones found by the buyer become leverage.

FL Disclosure Requirements — Plumbing

FL Statute 689.261 (Seller Disclosure) requires disclosure of material defects known to the seller not readily observable by a buyer.

Condition Must Disclose? Notes
Known active leak Yes Past or present leaks
Prior slab leak (repaired) Yes Include repair method and contractor
Polybutylene pipe (if known) Yes Material defect affecting insurability
Known cast iron failure Yes Document camera inspection
Water heater age Recommended Appears on 4-point anyway
Unpermitted plumbing work Yes FS 553.84 liability for non-disclosure
Septic system issues Yes FS 381.0065
Well water (if applicable) Yes Water quality test results

Non-disclosure liability: FL courts have awarded damages against sellers who failed to disclose known defects. FS 553.84 allows buyers to sue contractors — and sometimes sellers — for code violations not disclosed.
