Relocating toilet flange and main for basement bath.

I want to relocate this but there is terra cotta line
blocking it. Either have to go under or over, i guess. Best option seems to be go under if its ok to have a big main p trap under slab??

If I go over, barely enough room for a slab, maybe 1/2" to 1". Not to mention new flange for toilet will be way too high.

Can I go under with some 90's? Will it need a clean out?

After posting, I started thinking maybe just move the toilet a little to the left instead of trying to go around the terra cotta line.

Next challenge:

If I move it to the left can the y go in the direction displayed coming from lav and shower?? Disregarding the extra y on the other side.

This is the plan:

Have to get some clearance between the toilet and shower. The shower can't move because there is an I beam along the ceiling parallel to the adjacent wall. Not enough height.

What are you going to do with the double Y fitting that you show attached to the toilet bend?

As installed ,you will fill the two inch pipes with sewage every time the toilet is flushed--

And what's that old tile line for?
At some point it's going to fail and need to be dug up and replaced.
Looks like now would be a good time to do it.

Are you planning on sending toilet waste into your shower line? Because with that wye you have positioned the way you do like oh'mike said everytime you flush the commode some sewage will go into the shower branch.

Not to mention how would you expect the shower to drain into the wye and take that 135 degree turn???

Or maybe everyone is just misunderstanding your intention??

I have a toilet, lav, and shower that have to go to this "main outlet". I need to know how to properly "route" the lines.
Maybe I have to put the toilet to the right of existing position. Or Y everything right above the main outlet with a straight 4 with a 2 out the side?

Not sure what's up with the tile line. I could sketch a layout of what I think it's for. But guessing the basement floor drains and main sewage are two separate lines leaving the house. It's 80 yr old house. It's heading right for an outside wall. I could replace yes and maybe just junction with the other line??

So just reverse the Y direction and its ok??
I'm really limited by where I can place things in this space and that main is in a bad spot for where things must be placed and there's a terra cotta pipe next to it limiting the position of the toilet to somewhere only on that wall but not in the middle where it is now.

The top and left are outside foundation. The bottom wall, btw, has a low I beam parallel to it.

You need to take a photo standing further back and designate where your main line is, where you are putting your toilet, shower and lav.

By the way have you thought about how this bath group is going to be vented?

Edit: looks like you posted the drawing as I was posting this response.

Not sure about extra venting. I was told the vents are supposed to be up to the ceiling, at least. No, I haven't thought about it.

You should consider it. They are required.
