FAQs
What is polybutylene piping and why is it considered outdated in Louisville homes?
Polybutylene (PB) is a gray, blue-gray, or black plastic plumbing material installed in many Louisville-area homes from the late 1970s through the mid-1990s. Over time, the pipe reacts with chlorine and other disinfectants in municipal water, causing it to become brittle and prone to sudden, catastrophic leaks. Because of its high failure rate, PB is no longer accepted by Kentucky plumbing codes, and most insurers either surcharge or deny coverage for homes that still have it.
How can I tell if my house has polybutylene pipes?
Look for flexible, gray or bluish-gray plastic pipe between ½" and 1" in diameter. Common locations include: exposed supply lines near your water heater, unfinished basement ceilings, crawl spaces, and the pipe feeding your water meter or shut-off valve. PB pipe is usually stamped with “PB2110” or “PB2110 SDR11.” If you’re unsure, a licensed Louisville plumber can perform a free inspection and confirm through visual checks and basic water-pressure tests.
What are the benefits of upgrading from polybutylene to PEX or copper?
Upgraded piping eliminates the sudden-leak risk that PB poses, increasing your home’s resale value and providing peace of mind. New PEX-A or Type L copper systems: • carry a 25- to 50-year manufacturer warranty, • can withstand higher water pressures and temperatures, • improve water clarity and taste versus aging PB, • reduce insurance premiums, and • meet or exceed the latest Kentucky Plumbing Code adopted by Louisville Metro in 2021.
Will the pipe replacement require cutting into my walls and floors?
In most cases, yes, but reputable plumbers use minimally-invasive “home-run” techniques. For slab-on-grade homes we route new PEX through attic chases or soffits, limiting demolition. Typical single-family jobs involve 6–10 small drywall access holes (4"×4") that we patch, mud, and texture afterward. Homeowners can usually remain in the house, with water shut off only during final tie-ins (2–6 hours).
How much does a polybutylene replacement cost in the Louisville market?
Pricing depends on home size, story count, and whether you choose PEX or copper. As of 2024, the average costs are: • 1,200–1,600 sq ft ranch: $3,800–$5,500 (PEX) or $6,500–$8,500 (copper). • 2,000–2,800 sq ft two-story: $5,200–$7,400 (PEX) or $9,000–$12,000 (copper). • Larger/custom homes: $7,500+ (PEX) or $13,000+ (copper). Estimates include permits, materials, labor, drywall/paint repair, and a one-year workmanship warranty.
Do I need permits, and how long does the upgrade take?
Yes. Louisville Metro Department of Codes & Regulations requires a plumbing permit and inspection for any whole-home repipe. Our team handles the paperwork, schedules rough-in and final inspections, and provides the homeowner with passed-inspection documentation for insurance or resale. Most repipes are completed in 2–4 working days, with inspections on day 2 or day 3 and final drywall/paint touch-ups on the last day.
