I also have a slow tub drain question:
Like the other thread, my tub is also plumbed the same way (drain pipe runs back and under the full length of the tub). I haven't measured the drop in pipe, but will as this could explain things. Mine backs up more like 2" in 15 minutes however. I have removed the trap and snaked the pipe, all of which are clean.
My question is about the drain in the tub itself. It seems that due to the pop-up mechanism, the hole through which water flows is very small. (Kohler Clearflo) Could it be as simple as this? Any of you plumbers know if this drain set has restricted flow?
