What polybutylene is, and why it’s replaced

Polybutylene was a popular plastic water pipe in homes built from the late 1970s to the mid-1990s. Over time it has proven prone to sudden leaks, often at the fittings, and many homes in Northeast Florida from that era still have it.

Because of that history, some insurers and buyers ask about it during a sale or a new policy. Replacing it is a planned project instead of a surprise flood. We usually replace it with PEX, which installs quickly with few fittings.

How to spot polybutylene

Gray, blue or black plastic pipe

Flexible plastic lines, often gray, coming out of walls at sinks and toilets.

“PB” stamped on the pipe

Many poly pipes carry a PB2110 or similar code printed along the side.

Built roughly 1978–1995

Homes from this period are the most likely to have it, but only an inspection confirms it.

Gray pipe at the water heater or meter

Look where the pipes enter the house and at the water heater connections.

How we replace it

  1. Confirm the material

    We check visible pipe at the water heater, meter and fixtures.

  2. Plan the repipe

    New routes planned through walls, attic or crawl space with minimal openings.

  3. Replace & test

    All polybutylene is removed from service and the new system is pressure-tested.

  4. Paperwork

    You get an invoice describing the work, which is useful for insurance and resale.

Polybutylene Replacement FAQ

Is polybutylene pipe dangerous?

It isn’t a health hazard, but it has a reputation for failing without warning, which can cause major water damage.

Can I replace only the bad sections?

You can, but the remaining poly is the same age and material. A full replacement is usually the better long-term value.

Will my insurance require replacement?

Policies vary. Some insurers ask about polybutylene or limit coverage. Check with your agent, and we can provide documentation once it’s replaced.

How long does replacement take?

About the same as a whole-house repipe: typically a few days for most homes.
