I am going to replace the drum trap under my 2nd floor bathtub as it is draining extremely slow. However, I am unsure of where the vent should connect in the waste line. See the attached picture for the current setup. D=drain, T=trap, V=vent, S=main stack under toilet. Right now the vent connects into the side of the drum trap. There is also another pipe that goes up about 18 inches at a 90 turn in the drain line (? in picture). I do not know what the purpose of this is.
Can I just run straight from the drain to a new P trap (get rid of the angled part) and if so where do I tie into the vent?
Thanks!
