Spacing of basement rough ins...

[Trickplay461]

Taking the next step to finishing my basement rough-in . This was all here when I bought the house ..The spacing between the toilet and the sink drain just seem to close. Am I missing something here? I pushed the vanity up against the wall to approximately where it will sit against the lavratory drain and it uses up all the space where the toilet should be. Short of tearing up the concrete, do I have any options for extending the plumbing to the left and creating more room?

Where's the vent above?

If it's directly above your stub-out below, the simplest solution would be to put a san-tee on the drain stub out you have poking up, with the inlet pointed into the stud wall away from the toilet. Then you can run the trap arm through the wall until you poke out with a long turn 90. A 1-1/2" trap arm is limited to 42" in length for the UPC, and 72" for the IPC, not sure which one you are under.

Thanks for the reply!

I'm in NJ and they use NSPC. I included a diagram of my basement layout. There is a 2" vent stack coming through the ceiling from the floors above which stops at ceiling height and is capped off. My neighbor has a similar set up and he told me the builder left it there to finish the vent needs. The vent stack is roughly 10 to 15 ft from where I intend to put the sink. The sewer stack comes down into the basement from above and sits about 5 feet above the floor. Is what you're suggesting still possible in this scenario? Can I still move the vent stub to the left using a sani T to give me the added space to install a vanity? then planned on running it above the sewer pipe in height (AT LEAST 6FT HIGH) or whatever height I needed to then line it up with the ejector pump and then eventually tie into the ceiling vent. Can I run the vent stack above the sewer pipe or is height a problem? Vent pipe will run right past the sewage ejector pump which I will tie into to vent both the sink and ejector pump w/ 2" vent. I will also be tying the ejector pump into that sewer stack that runs along the wall. I'm strictly DIY and new to doing this type but it doesn't seem that difficult. Any and all help would be greatly appreciated, thank you !!

OK, the NSPC maximum trap arm length for a 1-1/2" is 5'. Certainly the local solution of using a san-tee and a trap arm partially in the wall to get the vanity farther from the toilet will work.

And I think your proposed 2" vent run to tie into the vent stub is fine. As to the details on the sewage ejector pump, I'm not familiar with those.
