Basement bathroom relocation?

tigerbalm2424

Looking to relayout the basement bathroom. Basement has yet to be finished.




I am attempting to move the intended location of the bathroom from the south side of basement to the north side (where it says proposed basement). How can I get rid of or reroute the existing drains/vents located on the south side of the basement? I dont plan on doing this until the winter months but I have no problem cutting up sections of the floor.

I'm not a pro plumber, just a long-time DIYer.
The main problem that you may run into is the depth of the main drain line that you need to connect the new bathroom line to. There needs to be 1/4" of decline per linear foot toward the existing main line.
Can you talk to the original builder or plumbing sub or owner to find out?

That was my first thought, but I was unable to track down the contractor/builder/ or owner.

Open up that cleanout near the water main and use a snake to see if that's where your sewer exits the house. It looks like it does because of its location. If so, that's your target area to pick up the 3 or 4" main drain. The main drain line currently travels some route between the cleanout and where your upstairs bathroom drain enters the concrete slab. Cut open a small area immediately next to the cleanout (opposite side of the cleanout from the wall) and dig down to the main (you can follow the cleanout pipe down to the main). Cut a trench from there to your new location.

As far as your old location I would just leave it. You never know what the future holds.
