Polybutylene Pipes in Pittsburgh Homes: What Homeowners Need to Know Before It’s Too Late

Polybutylene Pipes in Pittsburgh Homes: What Homeowners Need to Know

If your home was built in the late 80s or early 90s—especially by builders like Maronda Homes—there’s a chance you may have polybutylene piping hidden behind your walls.

And here’s the truth most homeowners don’t realize…

👉 These pipes can look perfectly fine… right up until they fail.

In this guide, we’re going to break down:

• What polybutylene pipes are

• Why so many Pittsburgh homes have them

• Why insurance companies don’t want anything to do with them

• How this can affect selling your home

• And what you can do to fix it the right way

Lets Dive into Polybutylene Pipes in Pittsburgh Homes.

What Is Polybutylene Piping?

Polybutylene (often called “PB”) is a type of plastic plumbing pipe that was widely used from 1978 through the mid-1990s because it was:

• Cheap

• Easy to install

• Flexible

At one point, it was installed in millions of homes across the U.S.

In Pittsburgh and surrounding areas, many production builders—including developments built in the 90s—used this material for water supply lines.

Why So Many Pittsburgh Homes (Including Maronda Builds) Have It

During the 90s building boom:

• Builders were trying to keep costs down

• Polybutylene was faster to install than copper

• It was marketed as “the pipe of the future”

👉 So entire neighborhoods were built using it.

If your home was built:

• Late 80s

• Early to mid 90s

There is a real chance your home still has it—even if parts of the plumbing have been updated.

The BIG Problem: Why Polybutylene Fails

Here’s where things get serious.

Polybutylene doesn’t fail like normal plumbing…

👉 It fails from the inside out

What causes it?

• Chemicals in public water (like chlorine) attack the pipe

• The pipe becomes brittle over time

• Micro-cracks form internally

Eventually…

💥 The pipe bursts with little to no warning

This happens because polybutylene degrades when exposed to common water disinfectants, leading to cracking and leaks

Why Insurance Companies Don’t Want to Cover It

This is a HUGE deal for homeowners.

Many insurance companies:

• Refuse to insure homes with polybutylene

• Charge higher premiums

• Exclude water damage coverage entirely

Why?

👉 Because these pipes are a known risk

They have a long history of:

• Sudden failures

• Massive water damage claims

• Costly payouts

In fact, insurers often require full replacement before issuing or renewing a policy

What Happens When You Try to Sell Your Home and you have Polybutylene Pipes Show Up On Your Home Inspection Report?

This is where polybutylene becomes a deal killer.

During a home inspection:

• The inspector identifies PB piping

• The buyer’s agent raises concern

• The buyer gets nervous (or their lender/insurance steps in)

👉 Then one of three things happens:

1. Buyer walks away

2. Buyer asks for a large price reduction

3. Buyer requires full repipe before closing

If you’re currently going through this, you’re not alone—and it’s something we help homeowners navigate all the time

.👉 Don’t let this deal fall apart. If your home has polybutylene piping, get ahead of it before it costs you thousands in negotiations.

Homes with polybutylene are:

• Harder to sell

• Worth less

• Often sit longer on the market

Why It’s Not Worth “Waiting Until It Leaks”

A lot of homeowners think:

“If it’s not leaking, I’m fine…”

That’s the dangerous part.

Polybutylene:

• Can look perfectly fine on the outside

• Deteriorates internally

• Can fail suddenly with no warning

Leaks can cause:

• Flooding

• Mold

• Structural damage

And sometimes…

👉 Insurance won’t cover it

The Solution: Upgrading to PEX Piping

The good news?

👉 There is a permanent fix.

At Revelation Plumbing, we replace polybutylene systems with PEX (cross-linked polyethylene).

Why PEX is the upgrade:

• Resistant to chlorine and chemicals

• Flexible and durable

• Long lifespan

• Designed for modern water systems

PEX has become the go-to replacement because it doesn’t suffer from the same internal breakdown issues
