Haven’t run into this before – in-construction house, phase inspection, plumbing is 3/4-1 inch white plastic-looking piping; easy to install, etc. Builder claims plumber says it’s “better than copper”, “I’ll attach copper fittings to it at each extension from the wall,” “nobody steals this [as they do the copper]”.
I have a call in to both the city and the county for the code information (I know, I don’t do code!). The ‘red flags’ for me comes from our discussions of polybutylene, which this is not. However, the elbows and other fittings look a lot those of the poly, but not crimped. I’ll try to attach a photo.
Thanks, in advance, for any light you can shed; direction to go to determine its suitability.
