Is there another kind of gray plastic piping out there other than Polybutylene pipe (PB)? I heard of a class action lawsuit a few years ago over PB. I knew it as a gray flexible plastic pipe.
I was asked to add a branch water line for a store. The existing piping is gray pipe but it was installed about 3yrs ago. I don’t know if it is PB or not. If so, then are fittings still being made for it or with the class action settlement did it pretty much go away not to be used ever again? Since I need to put in a T fitting into this gray pipe to make the branch are there fittings available that allows me to T off of PB?
