If your Greenacres home went up in the 1980s or very early 1990s, there is a real chance its water supply lines are polybutylene — the gray plastic pipe that became one of the most problematic plumbing materials of its era. For many owners here, the pressure to replace it comes from the insurance company before it comes from a leak.
Why this matters in Greenacres
Greenacres expanded rapidly during the 1980s building boom, exactly when polybutylene was the cheap, fast-to-install supply pipe of choice. As a result, a number of the area’s subdivisions from that era were plumbed with it. Two things make poly a present-day concern:
- It fails. Polybutylene and its fittings can grow brittle and crack over time, sometimes leaking suddenly and causing significant water damage.
- Insurers treat it as a liability. Many Florida carriers will not write or renew coverage on a home with active poly, or require replacement as a condition of the policy.
That combination has made polybutylene replacement one of the most common repipe-driven projects in 1980s Palm Beach County neighborhoods like Greenacres — often on a deadline set by a carrier.
How to identify polybutylene
- Color: usually gray, sometimes blue or black, flexible plastic (not rigid)
- Where to look: at the water heater, under sinks, at the washing machine connections, and where the main line enters the home
- Fittings: often crimped metal or plastic fittings, sometimes stamped with codes such as “PB2110”
- Era: homes plumbed roughly 1978–1995 are the prime candidates
The insurance angle
Polybutylene is one of the most common reasons an otherwise sound older Florida home gets flagged at insurance application or renewal. Some carriers decline outright; others require documented replacement. A completed, permitted repipe gives you paperwork to show your carrier. Rules vary by company and change over time, so confirm your specific situation with your agent — this is general information, not insurance advice.
Your replacement options
PEX
PEX is flexible cross-linked polyethylene — the most common modern replacement for poly. It routes quickly with fewer fittings, keeps demolition down, and is widely used across Florida, which usually makes it the lower-cost path for a whole-home repipe.
Copper
Copper is rigid and long-established, chosen by some owners for its track record, at a higher material and labor cost. A repipe replaces all the accessible poly supply lines through walls, ceilings, and attic space, then patches the openings. A licensed plumber can weigh PEX vs. copper against your layout and water chemistry.
What affects the cost
- Home size & number of bathrooms — more fixtures means more pipe and more connections.
- Material choice — PEX vs. copper changes both material and labor cost.
- One vs. two stories and attic access — routing difficulty drives labor.
- Drywall, tile, and finish restoration after the work
- Permit and inspection fees through your local building department
| Scope of work | Directional planning range |
|---|---|
| Whole-home poly replacement in PEX | $4,500 – $13,000+ |
| Whole-home poly replacement in copper | $7,000 – $18,000+ |
| Drywall / finish restoration after repipe | $1,000 – $6,000+ |
Permits & who can do the work
Replacing supply piping is permitted work in Florida. In Greenacres the permit and inspections run through the City of Greenacres / Palm Beach County building department (the “authority having jurisdiction,” or AHJ). Work should be performed by a Florida state-licensed plumbing contractor, who normally pulls the permit and schedules the required inspections. Keep the permit and final inspection documentation — it is what you show your insurer to confirm the poly is gone. Confirm current permit fees and requirements with your specific AHJ — they vary and change over time.

Frequently asked questions
What is polybutylene and why is it a problem?
Polybutylene (often called ‘poly’ or PB) is a gray, blue, or black flexible plastic supply pipe used widely from roughly 1978 to 1995. It was inexpensive and easy to install, but it became known for failing — the pipe and especially its fittings can become brittle and crack over time, sometimes leaking without warning.
That track record is why it is treated as a liability today.
Why won’t my insurer cover polybutylene?
Because of its failure history, many Florida property insurers will not write or renew a policy on a home with active polybutylene supply lines, or will require it to be replaced as a condition of coverage.
Carriers’ rules differ and change, so confirm your own carrier’s position with your agent. This is general information, not insurance advice — but in practice, poly is one of the most common reasons an older Greenacres home gets flagged.
How do I know if my Greenacres home has polybutylene?
Look at exposed supply lines at the water heater, under sinks, and where the main enters the house. Polybutylene is a flexible plastic pipe, usually gray (sometimes blue or black), often about half-inch or three-quarter-inch, frequently joined with crimped metal or plastic fittings.
Many 1980s and early-1990s Greenacres subdivisions were plumbed with it. A licensed plumber can confirm it positively.
What replaces polybutylene?
A whole-home repipe replaces the poly with modern supply pipe — most commonly PEX (flexible cross-linked polyethylene) or copper. PEX is fast to route with fewer fittings and is widely used in Florida; copper is rigid and long-established at a higher cost.
A licensed plumber can recommend based on your layout and water chemistry.
Do I have to replace it if it isn’t leaking yet?
Replacement is about risk and insurability, not just current leaks. Poly can fail suddenly, and if your carrier requires replacement for coverage, waiting can leave you uninsurable or exposed.
Many Greenacres owners replace it proactively to protect both the home and the policy. Weigh your carrier’s requirements, the pipe’s age, and your budget.
Do I need a permit?
Yes — replacing supply piping is permitted work. Your licensed plumbing contractor typically pulls the permit through the City of Greenacres / Palm Beach County building department and schedules inspections.
Verify current fees and requirements with your authority having jurisdiction.
