Plumbing is probably one of my least favorite things to do in a DIY project. Most people say they don’t like electrical, because they are afraid to get shocked, or killed. I have this little thing in my basement called a breaker box, that solves that issue for me. I will say that I have learned a ton about venting systems and back pressure and all of that. I have had to redo the vent in the kitchen several times. I’ll have to do it once more time before it’s correct.
