Im currently designing my house, im an engineer with a decent amount of experience I'm just very confused when it comes to plumbing. i even designed my house around having all fixtures on one wall for simplicity. however, i have two main questions and any help will be gratefully appreciated. First, should i run my 4" main drain right under my fixtures or should i have it offset as in the PDF's attached? Second and most important, how would you pros plumb my bathroom setup? im very confused when it comes to venting. i understand the science with the P-traps but i just dont know how to lay it out. can i use a air emittance device instead of running a tall vent? I live in Quakertown PA and will be building a small 24x50 house on slab and will have the plumbing underneath the slab of course. thank you all in advance!
