Bathroom plumbing drainage piping

[StuTDavis]

We're working on adding a bedroom/bathroom/closet over an old carport. The existing carport pad was left in place, and now it's adding to the problem. We're having trouble getting enough slope for the main drainage pipe, with trying to tie the toilet, sink and shower into the central piping. I was wondering if it's possible to tie in the sink and shower drainage lines directly into the main line further down the line. As in, just hooking the toilet drainage directly at its initial junction, and splicing in the sink and shower drain lines further down in the main line. Would this work, and would it be OK under code?

Thanks,

Stu

and would it be OK under code?

that is the main problem, this is a UK based site and we have no idea about your local codes, i suggest you check with your local "codes office" to see what they say

Thanks,
