The girl who lives on the first floor apartment under my daughter's
second/third floor apartment had this problem.
Here is my daughter's reply to the original post.
Melissa had water coming out of her chandelier, when we were getting our
bathtub redone. Don't forget, after all the work, it looks like in the end it
was a bad seal on the toilet causing the leak into her apartment. But the other
work needed done, too -- there was a leak from the bathtub, but I think this
was just rotting out our walls, not leaking into Melissa's.
