Hi,
I am the homeowner of at 20 year old townhouse that leaks whenever water from the shower, sink, or tub is turned on in either of the 2 upstairs bathrooms. I have had all the tub drain components and shower heads replaced, but there is still a leak. The leak has left a water stain on the downstair ceiling. Also, I noticed by bathtub in now beginning to squeak. Does anyone have any idea what is causes this leak?
