Thank you Terry. HJ, the plumber the company sent was a 20 year old young man, and I wasn't comfortable in his knowledge. I also think there are some things wrong with his plan, which was why I was asking for some help. He also quoted me 1500 to do the work, which I think is way to much for just a DWV system. I was hoping I could do it myself, which the permit office said I could, as long as everything meets code. There are only 2 plumbing companies where I live, and the other company has had many complaints from friends and family, and is not licensed.
