How can I determine the source of a second floor bathroom leak ?
I have a second floor bathroom and when soemone is showering water has begun pouring out of the air vent on the first flooor, under the bathroom. I recently had a pipe burst between the floors during a freeze and had to have everything torn out and redone. I would like to correct this witohut tearing out the ceiling again and going through those repairs if necessary.
During that time, the plumber who came and fixed my pipe checked the upstairs drain and told me there was no problem with it prior to finding the burst pipe. Since we have moved back into our home (the entire first floor was flooded and completely gutted) this new water leak began within the past two days.
What could be causing this and is it something I may can repair without having to tear out the ceiling to find?
