Connecting shower drain under slab?
Hi all - this is my first post, but I've used this forum many times to get info for my DIY projects. Definitely the best DIY plumbing forum I have found!
I'm renovating a basement bathroom which previously had a toilet and a corner shower unit. We are enlarging the bathroom and moving the shower a couple feet further away from the toilet so I chipped out the floor to get to the drain plumbing.
I found the existing shower drain was a 1-1/2" pipe tied in directly to the toilet drain with no venting. I presume this is incorrect. There is also a what appears to be a drain tile pipe running beside the toilet drain pipe. Any idea why that would be there?
The following pic shows the existing plumbing and is marked up to indicate the desired location of the toilet flange. The new shower drain will be approximately 5' directly to the right of the toilet flange.
Obviously I will have to remove some more concrete to redirect the drain tile pipe to be able to relocate the toilet flange, but what is the correct way to connect my shower drain (I'll change the pipe to 2") to the existing plumbing and how should I vent it. Would it be correct to connect the drain as indicated in green? I have full access to the ceiling and all four walls.
Thanks
