Urban Plumbing Inc. is a licensed Lake Zurich plumber specializing in whole-house repipes including polybutylene pipe replacement throughout the Northwest Suburbs of Illinois. If your Lake Zurich, Wheeling, Palatine, or Buffalo Grove home was built between 1978 and 1995, there’s a real chance you have polybutylene supply lines in your walls. This guide explains what polybutylene is, why it fails, how to identify it, and what replacement involves.
What Is Polybutylene Pipe and Why Does It Fail?
Polybutylene (often shortened to “PB” or just called “poly”) is a gray plastic plumbing pipe that was widely installed in residential construction from the late 1970s through the mid-1990s. It was promoted as a cheaper, easier-to-install alternative to copper supply lines, and millions of homes across the United States, including a significant portion of homes in Lake Zurich, Wheeling, Palatine, Buffalo Grove, and the broader Northwest Suburbs, were built with it.
The problem is that polybutylene reacts with oxidants in municipal water supplies, including chlorine and chloramine commonly used for disinfection. Over time, the reaction causes the pipe to become brittle and the brass fittings (where used) to dezincify and corrode. The result is progressive pipe failure, typically starting as slow leaks at fittings and eventually progressing to sudden bursts that flood walls and ceilings without warning.
A major class-action settlement in the 1990s acknowledged the systemic failure issues with polybutylene, but the settlement claims deadline passed in 2009, leaving current homeowners with the cost of replacement.
How to Tell If Your Lake Zurich Home Has Polybutylene
The easiest way to identify polybutylene is by visual inspection. Look in these typical locations:
- Behind washing machines (where supply lines tie into the wall)
- Under sinks and behind toilets (where supply lines connect)
- At the water meter or main shutoff valve
- In utility rooms or basements where pipes run exposed
- At the water heater connection
Polybutylene is gray (sometimes blue or black, though gray is most common in residential), typically 1/2-inch or 3/4-inch diameter, and printed with the marking “PB2110” along the length. The fittings are usually copper, brass, or gray plastic.
If you see gray plastic supply pipe in your Lake Zurich home and it was built between 1978 and 1995, you almost certainly have polybutylene throughout the house. The visible sections under sinks are only a small fraction of the total pipe running through walls and ceilings.
Why Lake Zurich Homeowners Should Address Polybutylene Now
Three factors make polybutylene replacement a serious priority for Lake Zurich homeowners:
Failure rates accelerate with age. Polybutylene pipes installed in the 1980s are now 35-plus years old, well past any reasonable service expectation. The failure rate is no longer theoretical.
Insurance coverage is changing. Several major homeowners insurance carriers have started declining coverage on polybutylene-related water damage in new policies or non-renewal scenarios. Existing claims are still typically covered, but you may not have that coverage indefinitely.
Failures don’t give warning. Unlike copper pinhole leaks that often weep slowly before bursting, polybutylene failures frequently happen suddenly at fitting connections. A 2 a.m. failure inside a second-floor wall can cause tens of thousands of dollars in water damage before you discover it.
The Environmental Protection Agency’s drinking water resources cover related pipe material concerns, and the issues with polybutylene specifically are well-documented in industry literature.
What Whole-House Polybutylene Replacement Involves
Urban Plumbing handles polybutylene repipes in Lake Zurich, Wheeling, Palatine, and the surrounding Northwest Suburbs. The process generally includes:
- Free in-home assessment and written estimate
- Identification of all polybutylene runs throughout the home using accessible wall, ceiling, and crawl space inspection
- Strategic drywall cuts at access points to minimize finished-surface damage
- New PEX or copper supply lines run through walls and ceilings
- Manifold installation where appropriate for cleaner fixture-by-fixture shutoffs
- Tie-ins at every fixture: sinks, toilets, tubs, showers, water heater, washing machine, dishwasher, refrigerator ice maker, and outdoor hose bibs
- Pressure testing and inspection
- Coordination with finish contractors for drywall patching and paint matching
A typical Lake Zurich single-family home takes 3 to 5 days for a full repipe, depending on size, finish complexity, and access conditions. We provide a detailed written timeline as part of the estimate so you know what to expect.
Cost Range for Lake Zurich Polybutylene Repipes
Total cost varies based on home size, number of fixtures, accessibility of pipe runs, and finish patching scope. As a general range, whole-house polybutylene replacement for a typical Lake Zurich single-family home runs $8,000 to $15,000. Larger homes with more fixtures, complex floor plans, or extensive finish patching can run higher.

Frequently Asked Questions
Is polybutylene replacement covered by homeowners insurance? Replacement itself is typically not covered. Resulting water damage from a polybutylene failure may be covered, but coverage is changing and varies by carrier. Check your specific policy.
Can I replace only the visible polybutylene sections? We don’t recommend partial replacement. The hidden runs inside walls and ceilings are the same age and material as the visible sections, and the failure risk is identical.
How long does Urban Plumbing’s repipe work take? 3 to 5 days for a typical Lake Zurich single-family home. Larger or more complex homes may take longer.
What pipe material replaces polybutylene? We typically install PEX with manifold systems for cleaner shutoff control. Copper is also available where preferred. Both materials are well-tested and significantly more reliable than polybutylene.
