I'm adding a basement bath (toilet, shower & sink) and need to know venting requiements.
There is a first floor half bath above that vents through the roof. So right now there are two fixtures on this stack. The bath I am adding is directly below. The toilet will be 1' from the stack, shower will be 3' and sink 4'.
Do all three of these fixtures need to be vented? Is AAV a good choice? If vent is required I need some help with the toilet. The toilet will sit almost directly over the existing horizontal line making a vent difficult since it will not run horizontal and the is almost no verical room. The only thing I see working is a sanitary tee with a inlet.
Thanks for any advice.
