Polybutylene Pipe — Know Your Risk
Polybutylene pipe (gray plastic, stamped "PB2110") was installed in hundreds of thousands of FL homes built 1978–1995. It fails without warning due to chlorine degradation. If your home was built between 1978–1995, have a plumber confirm your pipe material before a failure occurs. FL insurers increasingly deny coverage or add exclusions for homes with active PB pipe.
Florida Trenchless Advantage
Florida's sandy soil and high water table make trenchless replacement (directional bore) faster and less disruptive. It avoids damaging FL landscaping and irrigation systems.
Permit & City Coordination
All FL main water line replacements require a permit. The water meter connection (at the street) is city/utility property — your plumber coordinates the meter shutdown with the utility. Allow 1–5 business days for scheduling.
FL Insurance Warning
Several major FL homeowners insurers now exclude or limit coverage for polybutylene pipe claims. Check your policy before a failure occurs — proactive replacement may lower your premium.
FL Hard Water + Copper Pinhole Leaks
South Florida's chloramines + hard water + copper = a pinhole leak epidemic in homes built 1960s–1990s. Signs: water stains on walls, ceiling discoloration, and unexplained water bill spikes. If your copper line is 40+ years old, schedule an inspection.
Active Main Line Break — Emergency Response
- Locate and shut off your main shutoff valve (usually near the meter box at the street or at the home entry).
- Call for emergency service — 24/7.
- Notify your city/utility if the leak is near or at the meter.
- Document all damage with photos & video for your insurance claim.
- Do NOT restore water until your plumber confirms the repair is complete.
Who Owns What?
The utility owns everything from the city main up to and including the meter. You own the line from the meter to your home — including all repairs and replacement costs on your side. (City Main → Meter → Your Line → Home.)
