OK, I'll buy that, but how often does it have to be replaced? Every two years, five years, or even 10 years. The replacement looks simple enough, but is there a tool that can be used to unscrew that part, and down the road will your company be around to be able to supply those types of replacement parts? I'd hate to have to tear up my bathroom floor just because we could no longer get those replacement parts. While it seems a clever adaptation to a remodel problem, that rubberized PVC/ABS will not last as long as piping out of PVC.
