What Is Polybutylene Plumbing? Everything Homeowners Need to Know

If your home was built between the late 1970s and the mid-1990s, you might be living with a hidden issue behind your walls. Welcome to the world of polybutylene plumbing – a silent troublemaker that could be causing more harm than you think. At Riser Plumbing and Drain, we believe informed homeowners are empowered homeowners, so let’s dive into everything you need to know about this outdated piping material.

What Is Polybutylene Plumbing?

Polybutylene plumbing refers to a type of plastic resin piping known as polybutylene (PB), used extensively in residential and commercial buildings for water distribution from the late '70s to the mid-'90s. The main appeal of polybutylene pipes at the time was their low cost, flexibility, and easy installation.

However, what seemed like a revolutionary material quickly became notorious for its tendency to degrade and fail. Riser Plumbing and Drain has dealt with countless homes that still have these outdated systems in place, often without the homeowners even realizing it.

Why Were Polybutylene Pipes So Popular?

Polybutylene was marketed as the future of plumbing. Lightweight and easy to install, it significantly reduced labor costs and installation time. For builders, it was a dream. For homeowners, it meant lower costs.

Unfortunately, what we now know is that polybutylene reacts poorly to oxidants like chlorine in municipal water, causing the pipe to become brittle and eventually fail. Riser Plumbing and Drain has replaced many such systems before major water damage occurred, and we always recommend a proactive approach.

Signs You Have Polybutylene Pipes in Your Home

Does your home have polybutylene piping? Here are a few signs:

Pipes are gray, white, or blue.
Stamped with "PB" and a series of numbers.
Often found in basements, near water heaters, or in walls.

If you spot these characteristics, contact Riser Plumbing and Drain for a professional inspection. We’ll confirm the type of piping and help guide you through the next steps.

Risks of Keeping Polybutylene Piping

The main issue with polybutylene pipes is their high failure rate. Cracks can form inside the pipe and go unnoticed until there's a serious leak or rupture. This can lead to extensive water damage behind drywall, under floors, or in ceilings.

Leaks not only damage the structure of your home but also promote mold growth and increase your utility bills. Riser Plumbing and Drain emphasizes the importance of replacing these pipes before a failure occurs.
