A tub above our kitchen started leaking. I removed the ceiling and replaced the tub drain gasket and it was good for a couple months... however, now it is leaking again… I slowed down and took a much closer look this time…
The leak looks like it is not coming from the drain! the water seems to be coming between the steel tub and Styrofoam than is adhered to the bottom… I see no cracks in the tub…
Our tub has Styrofoam under it and was sprayed with a black plastic coating to protect the foam. the first time I repaired the drain I actually cut the black plastic back because it was under the gasket and I figured I needed a smooth surface….
That got me to thinking about the overflow…. what if water is running down wall (shower mode) and getting between the black plastic coating and the steel tub and gravity is pulling the water down near drain hole….
I can't think of any other explanation and I am having trouble googling for related issues… ideas?
