    A little over a year ago we installed a new shower with
    pan and drain. The drain is PVC and was clogged. The owner
    poured a liquid drain cleaner down the pipe and slowly the
    water drained down. She told me that when the water filled up
    in the shower it started leaking in the ceiling below so I removed
    the drain cover to see that the PVC drain pipe was actually
    degrading or melting. I can stick a screwdriver right into the sidewall
    of the pipe. I called the company that makes the drain cleaner
    and they assured me it was not the drain cleaner.
    Is there a chemical in shampoo or soap or some other cleaning
    product that would eat away at PVC like that??

    Some chemical drain cleaners can generate quite a bit of heat. I have seen pipe damaged by them. If you read the label they are not supposed to be allowed to stand in a clogged drain.
