Thoughts on this one? I couldn’t find any section of the pipe where the mfg logo was clear enough to say it was or wasn’t for certain… it looked like PB, except for the fittings, and there was no marking with the “PB” indicator… thoughts?
I never see poly with those fittings. The labeling is blurry which I often see. The gray color is a huge clue. I’d write it up, “Supply plumbing appears to be polybutylene which has known problems and failures, and should be evaluated by a qualified plumber” or words to that effect.
