Hello,
I own a excavation company that installs water mains, services, storm, and sanitary pipe outside, my interior plumbing knowledge is lacking.
My new basement bathroom was just framed and I am getting ready to cut the slab.
I just wanted to get some opinions before I started cutting if this layout will work.
One concern is venting, I will probably have to use a AAV in the lav and am not sure if that is sufficient for venting the toilet and shower tub.
Another concern is after cutting the 4" existing cast and placing a WYE to service the bathroom the wye is pointing downhill of the bathroom drains. So I will be draining from the bathroom downhill to a wye and then back up to the existing cast drain pipe. This is hard to explain, I will add a picture.
Thanks and below are the pictures.
Proposed layout
Existing wet vent
Connection to existing cast iron, this is the WYE in question.
