I’m in the process of remodeling my (very old) houses current only bathroom, and from everything in reading here and elsewhere online it looks like my plumbing isn’t currently vented correctly.
The attached picture is my current set up, 4” CI coming in one corner of the laundry room, with a 2” CI vent immediately, then 6’ after the vent is where all my drain connections in the house are tied in, washer, kitchen and bath sinks, tub and finally toilet last in line. This leaves my trap arms a little or a lot longer than I think they should be, and the vent connection up to 18’ away from the furthest fixture.
My current plan is to cut everything out, tie into the 4” CI with PVC, and add a 3” vent straight through the roof. I also want to add a second bath stacked above the first. My question is does the order of fixtures matter, and in my new drawing will anything need an individual vent that I would later tie back together in the attic.
