Well I guess I left out a couple steps!! I forgot to add that we would
be disconnecting the drainpipe that comes through the ceiling and
disconnecting the hot and col water leads before tilting the tub. I
think I will take your suggestion and cut a little hole in order to see
whats going on in order to assess the situation correctly. We do want
to install a proper trap...It's just getting the old one out that is
the problem!
