    That would seem to be the explanation on the face of it. Piping is made from heavier duty plastic. But I’ve heard that PVC can start leaking some nasty chemicals over the decades. Is that better or worse than microplastics?

      PVC fell out of use in the 2000s, most buildings use PEX now; but I don’t know how that compares.

        I believe I’ve heard that PEX actually breaks down and starts leeching chemicals into the water faster than PVC. It’s also a cheaper material. Most of the houses I’m familiar with are still installing PVC.
