What Is Polybutylene?

Polybutylene is a form of plastic resin that was mainly used for the piping of potable water. It’s also known as poly, poly blue, and PB. It was manufactured from the late 1970s until the mid-1990s and is mostly found in residential homes.

How Do You Tell You Have Polybutylene?


Polybutylene used inside your home can be found near the water heater, running across the ceiling in unfinished basements, and coming out of the walls to feed sinks and toilets. In some homes, plumbers used copper “stub outs” where the pipe exits a wall to feed a fixture, so seeing copper here does not mean that you do not have poly.


Polybutylene underground water mains are usually blue, but may be gray or black (don’t confuse black poly with polyethylene pipe). It’s usually 1/2″ to 1″ in diameter, and it may be found entering your home through your basement wall or floor, concrete slab, or coming up through your crawlspace; usually, it enters the home near the water heater.

What Makes It Fail?

What causes polybutylene pipes to deteriorate can be attributed to the oxidants in the water. With the increased usage of chemicals like chlorine and other bacteria-fighting ingredients, significantly more failures occurred. These oxidants react with the polybutylene making it brittle and helping in the development of micro cracks in the pipe that cause pipe bursting and severe floods.

How Long Does it Take to Re-Pipe a Home?

We aim to complete all re-pipes in one day. Once our work is complete a county inspector will need to inspect the work before the walls are restored.

Will We Have to Move Out During the Work?

No. We respect your privacy and do our best to work around your needs.

Will My Water Be Turned Off?

Yes. In most cases, it will be turned off if it’s a one-day project. If it goes into the second day or more, we could restore the water service each evening for your convenience.

Do I Have To Move Anything Out Of The Way?

Yes, we ask that you move any fragile pieces and personal property. We respect our customers’ homes and personal property.

Some People Have Told Me That You Need to Take Out the Walls. Is That True?

We will need to cut your drywall where the water lines are hidden. To some, the cuts may seem to be substantial, but we will minimize the damage the best we can. Unless, for example, you have an unfinished basement or the pipe is already exposed, then there’s less debris involved. We don’t repair drywall. Be sure to protect your home from dust.
