Is this what I think it is PB?????

[Jae Williams]

Looks like it could be...it is always best to search the pipe for a marking -- PB2110.

[Brian E. Kelly]

Most likely yes.

The piping appears to be polybutylene and this type of piping has a history of problems and should be examined by a qualified plumber and repaired or replaced as necessary.

The Insulation seems to be installed vapor barrier to the cold side. I would write that up also.

straight from 1000 Narratives:

1.Polybutylene, PB—Active water supply pipes appeared to be polybutylene plastic (hereafter, “PB”). It is believed that chlorine and fluorine react with PB, causing pipes to scale, flake, and become brittle. Micro‑fractures result, and the basic structural integrity of the system is reduced, thereby becoming weak and possibly leaking without warning. A home inspection cannot determine if PB water supply pipes are about to leak simply by looking at the outside of the pipes since they deteriorate from the inside, and they can split or burst under pressure at any time. Some insurance companies decline to offer insurance on homes with PB water supply pipes because of associated problems with it.
