We are having a debate as to what is causing the leak in our second flr bath that is leaking into the downstairs bath. The leak has been slow but has been going on for some time. My DH thinks it is a crack in the caulking that is causing the water to drip down into the ceiling. I think we have a slow leak in the pipes. Today the leak is so bad that water is actually dripping through the ceiling. At this point we have got to fix the problem. I just want to make sure that we fix the right problem.
Any ideas?
