Polybutylene pipe?

[Good Wife]

We worry more about old Masonite siding than we do about the plumbing.

Joyce,
Polybutylene pipe was used for water lines in the 1980's and 1990's. Poly is more prone to leaking, and there was a lawsuit over it. Thousands of homes in the triangle have polybutylene. Some homeowners replace it even if it never leaked.

Thanks Del,
I didn't know about it yet before.
