How to Identify Polybutylene Pipes: A Must-Read for South Florida Homeowners

how to identify polybutylene pipes

If your home was built between 1978 and 1995, there’s a chance it contains a hidden hazard behind the walls—polybutylene pipes. While once touted as an affordable plumbing solution, these pipes have a history of sudden failure, costing homeowners thousands in repairs and insurance claims.

In this guide, the expert team at DC Plumbing of South Florida explains how to identify polybutylene pipes, why they’re dangerous, and what to do if you find them. A quick inspection today could save you from a flood tomorrow.

 

🚰 What Are Polybutylene Pipes?

Polybutylene (PB) is a type of plastic resin used in residential plumbing systems from the late 1970s through the mid-1990s. PB pipes were popular for:

  • Hot and cold water lines

  • Main water supply lines

  • Plumbing systems in condos and mobile homes

In South Florida’s heat and humidity, these pipes deteriorate faster, making proactive identification especially important for local homeowners.

🧯 Why Were Polybutylene Pipes Discontinued?

Despite early popularity, PB pipes were found to:

  • React with chlorine in municipal water, forming micro-cracks

  • Degrade at joints and fittings

  • Fail without warning, causing water damage

The result? A massive class-action lawsuit (Cox v. Shell Oil) and nearly $1 billion paid out to affected homeowners.

 

🔍 How to Identify Polybutylene Pipes in Your Florida Home

Wondering if your home is at risk of hidden plumbing issues? Learn how to identify polybutylene pipes by following these simple steps and protect your property from unexpected water damage.

1. Check Your Home’s Construction Year

Was your home built or repiped between 1978 and 1995? If so, you’re in the high-risk window.

2. Look for Exposed Pipes

Inspect areas like:

  • Under sinks

  • Water heaters

  • Attics and crawlspaces

PB pipes are usually:

  • Gray, blue, or black

  • Flexible and plastic-like

  • Labeled with “PB” or “PB2110”

3. Examine Pipe Markings

Common labels include:

  • PB2110

  • CSA-B137.8

  • ASTM D3309

These markings confirm the pipe’s material and distinguish it from PEX or CPVC.

4. Inspect Pipe Fittings

Look for:

  • Aluminum or plastic crimp rings

  • Metal clamps or connectors

  • Loose or deteriorating joints

Any sign of stress or separation is a major red flag.

 

⚠️ The Dangers of Polybutylene Pipes

Still considering leaving them in place? Before you decide, learn how to identify polybutylene pipes and understand the serious risks they pose to your home—including sudden leaks, insurance issues, and costly repairs.

💧 Sudden Water Damage

PB pipes fail without warning, flooding your home and damaging walls, flooring, and valuables.

💸 Insurance Issues

Many insurers won’t cover homes with PB pipes—or will hike premiums significantly.

📉 Lower Property Value

PB pipes reduce your home’s resale value and can delay closings during inspections.

⚖️ Legal Liability

Selling a home with undisclosed PB pipes could land you in legal trouble.

Danny is wonderful. He’s professional, prompt, knowledgeable and he a good communicator as well. My business is very dependent on plumbing and this past year I experienced a few plumbing hardships. I called multiple plumbers before I was recommended Danny. He came out, looked at my problem, told he he could fix it and he did. Highly, highly recommended. He’s my plumber going forward. I couldn’t be any happier!

Had issues with copper water pipes that were leaking and were under ground. Danny figured out how to re route pipe and restore water back to bathroom without having to did you floors. He also installed new main water shutoff and garbage disposal.. I chose him because he was friendly, up front and is a master plumber, he is very knowledgeable and explained everything. I have Danny now locked in on my cell phone and I highly recommend him for any plumbing job

VERY SATISFIED. Danny was prompt to the appointment.  I had a bathroom sink which was not draining. I thought it was not going to be too hard but it turned out to be more difficult and stubborn than anticipated. Danny figured out what needed to be done and methodically cleared the line. He was extremely nice, took care not to get anything dirty and then cleaned up after he was finished. Very professional and would definitely use him again and refer others to his company.

TRUSTWORTHY! DILIGENT! HONEST! TIMELY! AFORDABLE! KNOWLEDEABLE! Danny is all of that!  I needed a gas cooktop installed in my kitchen.  After calling around, I learned that this was not something just any plumber would touch, but then there is Danny.  Although Danny knew exactly what to do, he still took the time to read through the directions to ensure he installed the new cooktop correctly.  Danny is extremely knowledgeable, diligent, courteous and reasonably priced.  He even showed up promptly, which speaks volumes for a contractor in south Florida.  Danny is extremely professional and most of all very trustworthy.  I will be using Danny for all my plumbing needs.  I highly recommend Danny!

DC plumbing is definitely the way to go. Danny is the owner and irreplaceable. If you would like to get a fair and accurate estimate not only is Danny your man, he is also very kind honest, reasonable and knowledgeable. He really took his time and charged less than these companies that do such supposed “superior” jobs. I have had many problems with big-name companies, such as Lindstrom to name one. They act as if they can fix all your problems because they have ads on TV. When the truth is they leave you with more problems than you started with. I refuse to be put through that kind of anxiety again Plus to fix a leak is about $700 or that’s even just to find one. RIDICULOUS!!! Danny on the other hand tells you everything up front and is very fair. if you are looking for plumber who is a nice, knowledgeable, thorough and friendly then I highly recommend giving him a call.

Frequently Asked Questions

Is your water bill higher than usual? If yes, take these next steps to rule out a plumbing leak:
– Check all toilets and flappers for any leaks. If there is a leak, this can result in a high-water bill if not maintained.
– Check all water fixtures to include sinks, showers, outside hose bibs, valves, pipes, etc. for any leaks.
– If you hear any water running inside your house, this can be an underground water leak or inside the walls.

It is recommended to flush out any tank type water heater or tankless water heater once a year.

The average life span of an electric tank type water heater is 10-12 years

Some signs of this are if a toilet is not flushing properly, a sink drain is slowing down or you shower/tub is filling up during use instead of draining as normal. 

Once per year.
