PB?

[John Dirks Jr]

Is this black supply line PB? It says Cresline on it. It comes into the house from a private well. It's about 1 1/2 inches in diameter. It felt like it was very thin walled. Is there a history of failure on this type?

It's high density polyethylene. No problems that I'm aware of so long as it isn't laid in a rocky trench.

It is almost certainly polyethylene pipe which is allowed for by International Code as water service pipe. Being plastic, this means it "must terminate within 5 feet inside of the point where the pipe penetrates an exterior wall or slab on grade." (IPC 605.3). Judging from the 14/2 Romex taped to it I think it might have exceeded the 5'.[]

John, did the pipe say "PB2110" on it anywhere? I can't say I've ever seen black PB, only grey in these parts.

There was other writing on the pipe but it was illegible. I could barely make out the larger Cresline title.

I've seen PE. This didn't look like any PE I had seen before. Check the link below. Scroll to the bottom. They show a black material they claim is PB.

What is pictured in the original post is HDPE.

Cresline manufactures PVC, CPVC, ABS, MDPE and HDPE.

Thank you gentleman. This house actually had both well and public water hookup. The well is serving the irrigation system.

The original public line was PB. It was changed to PE and I noticed that as soon as I saw it. I don't like the was they ran through the wall without a sleeve though.
