I'm remodeling my attic bathroom. In order to maximize my bathroom, I would like to put an elbow in my existing cast iron plumbing stack, run about 3feet of horizontal pvc, and then put another elbow in and vent it through the roof. The stack currently runs right through the middle of my attic bathroom. So by moving it over 3 feet, I can create a better floor plan. Is this against code to use 90 degree elbows in the main vent stack?
Thanks.
Thanks.
