New Basement Bathroom - Drain and Vent
Hello,
We would like to install a new bathroom (well, half bath = sink + toilet) in our basement. Currently, there is a toilet down there, sitting on a cast iron wye off the main sewer line for the house. We want to move the toilet by approx. 8 feet. The final position would be directly above the main sewer line as well.
What are our best options for roughing in the drains? Should we break up the concrete and hire a plumber to cut into the existing house sewer line (not a task I'd want to do myself)? Should we cut a trench in the floor and connect up to the drain where the existing toilet is?
Also, the existing toilet is not vented, and the main stack for the house is on the other side of the basement. I could probably find a way to run 2" ABS over to the main stack if I had to, but is a vent necessary?
Further information - concrete slab floor, and I'm tall so I don't want to put the toilet on a plinth or I'd hit my head.
Thanks for your advice,
-David
