I am tiling a small bathroom and the old ABS closet flange was not level. It was out about 3/8" from front to back. Plus it was not screwed to the subfloor very well. None of the screws were biting into the subfloor because the hole was cut to large. I decided to put in a new flange and and replace the subfloor around the flange. What I found out is that the 3" drain pipe to the flange is going slightly downhill thus making the flange not level. I really dont see anyway to correct this. I guess it worked ok for 30 years it should be ok. My other question, is there a rull of thumb for cutting the pipe going to the flange so the flange will set on the floor? I dont want to cut the pipe to short or too long? I currently have the flange pipe coming out of the floor until I finish tiling.
