A burst water-tank pipe sparks questions about its material

A homeowner reported that a line near their water tank burst while they were at work and that a plumber said it was crumbling inside. They later said the tubing was labeled “Bow superpex,” but the Reddit post did not establish what caused the failure.

Several Reddit commenters questioned whether the red tubing was standard PEX; others said a nearby section looked swollen. The discussion did not confirm the pipe’s material.
