Hello all, I'm doing a remodel of my home and need to re-do the plumbing for a bathroom. I have no clue as to how to set up my DWV and any layout advice other than it needs to slope towards the "way out of the house" would be extremely helpful. I'm trying to save a few bucks by doing it myself due to a "possible" upcoming layoff. JOY! Here is a picture of what I have going so far.
