1960 house. Main plumbing vent in the attic. From a distance it looks like cast iron, However it is joined with a coupling and on close examination the black is some sort of coating.Looking closely at the coupling, it looks like the pipe material itself is white.
I’m wondering if this is Transite. I’ve seen Transite pipe many times, but never with any coating like this. If it is, it appears to be pretty well encapsulated.
Can anyone confirm whether this is Transite (ACM) or some other material?
This may be a possibility. If you look closely at the joint, you can see that the pipe has been turned so that it fits the coupling. It also doesn’t look like the coupling has been cemented in any way ( I get the impression that this would be typical with Orangeburg). Also, though it doesn’t show well in the photos, the upper section is not quite square in the coupling, which also tends support the non-cemented joint theory.
I did recommend that my client have a hydrostatic test performed on the system. The plumbers were just starting as I wrapped up my walkthrough. I’ll find out how the test went. I’ll also find out if they identified the type of pipe.
When i got out of high school i worked for a company called underwater tel eye. Main job was running a camera threw sewers . it was different for sure . Best fun was when the camera got stuck and i had to crawl the pipe to get it back. good money though and all you could eat lolol
