I don't know exactly how to word this, so it is hard to search for an answer. I have looked all over and can't seem to find an answer.
I am roughing in a master bath on a slab. I will be using 4" pvc for the toilet and 2" for the shower drain. the sink will drain into the main stack.
there is very little give to 4" pvc, so when I am setting the slope in the ground under the slab, common sense (I think?) would tell me that since I am using a long sweep 90, the vertical pipe to the flange would be out of plumb to the same degree as the underground slope. Is there a trick to prevent this? this would go for the shower drain slope as well. I'm sorry if my question is confusing, I drew a picture to help me explain. Thanks for any help!
