I moved the vertical drain for my shower about 5 inches, and I've seen two ways to fill in the hole. In one method, a 4 or 5 inch pipe is fitted around the vertical pipe, and cement is poured around that pipe, leaving the 2 inch pipe not covered in concrete. The other method is to just cover everything with concrete, including the outside of the 2 inch vertical pipe. I've watched a bunch of videos on concrete drains, and people do it both ways, but never once has anyone explained why they do it the way they do. I had planned on filling the bottom most part of the hole with gravel, and filling it the rest of the way with quickcrete. I'm in Florida, by the way, where the ground never thaws, if that makes any difference. Thanks for any advice!!
