Good Day Everyone!
I have a project coming up where I'd like to 'elevate' a toilet waste line. Right now, it runs horizontally in a very low ceiling storage closet. The closet is going to be removed. Ideally, the horizontal pipe will be raised to be in the joist bay. This way the ceiling height in the existing room and the former closet can match.
My question is: Is a long sweep required for a toilet that's very close to the horizontal pipe? A plumber told me LS was required because the flange is close to the ell. Another told me it was not allowed vertical. I've searched the forum and, to be honest, got myself all confused about what's best here.
Since I tend not to find good words to describe stuff, I've attached a really rough sketch of "Existing" & "Proposed" (Apparently not such a good artist either! I just noticed I forgot to show on the drawing that there are no fixtures below the toilet line either. It goes down to the horizontal 4" (via wye & 1/8th bend) below the basement floor. It's the last thing on the way out of the house. A clean out is at the base of the stack.)
A long sweep ell will not allow the pipe to remain hidden in the bay, as the joists are nominal 4 x 6's. If I use a long sweep 90, I will have to lower the ceiling in the existing room and the former closet to hide the pipe. (Rather a large project- I'd prefer not do this.)
If I use a regular DWV ell (or-ideally- a street ell with a toilet flange that fits over the male end) I can hide the pipe in the joist bay and do minimal ceiling drywall work. (Yay!) I'd also like to avoid replacing the ell with a 4 x 3 closet bend because the room with the toilet is tiled. Three inch items will all fit the existing hole. With 4", I'd have to enlarge the hole in the tiles & sub floor. (Of course, no spare tiles!)
I don't know if it affects the decision about which ell to use, but the toilet is a 1980's variety not water saving. Of course, if it ever breaks, the replacement would be a water saver.
Thank you all very much for your input on this decision!
