Hi guys I've just noticed that after my upstairs tub was used, the ceiling in my living room directly below was wet. The caulking is fine I'm suspecting it's the bathtub overflow because I'm told the tub was filled to the top and I think water got in there. I took off the cover and it looks like the previous owner just tried filling the hole with caulking since there were globs in there. Is it worth the hassle of fixing it properly which would probably include making a hole in the ceiling to gain access, or would you just seal off the overflow and make sure whoever uses that tub never fills it that high? thanks.
