need to move toilet rough-in


Hi
I'm new to the forum and have reached out to the community seeking guidance on a washroom project which I've undertaken and messed up.

I've built walls in the basement for my washroom project where I did not considering the distant between the toilet rough-in and the wall. The distant of the pipe to the wall is approx 8". The rough-in was installed by the builder when I bought the house 13 years ago.

I though of working around the problem by installing an offset closet flange which one of the attached picture shows the distant of about 10" from the wall. However, in order for me to install the flange, I will need to cut around the drain pipe ... about 4" deep around the concrete.

I figured if I am going to rent a jack hammer and break into the concrete, I might as well look into moving the pipes. When I broke into the concrete, I discovered there is little I can do to move the pipes as there is another pipe that tee'ed into the main pipe. Here are some pictures I've captured hoping you can offer some guidance on how I can tackle this piping challenge.

Thanks in advance for any and all assistance.

Ron

Make the hole a little bigger, cut the smaller line and redo the whole thing. Not a whole lot more work really.

Yeah, don't forget you'll need 15" minimum clearance to the side wall too. So you're stuck rearranging a bunch of stuff. Not too hard though.

Toilets are readily available for 10.5" rough in. If you move the 3x2 wye and the 3" 90 a couple inches, you might get it. I don't recommend offset flanges either.

Thanks for the prompt response ...

Just for clarification ... the suggestion is cut below the 3x2 wye and reinstall a replacement from that point on? I'm wondering if that will still provide sufficient clearance if I don't use an offset flange.

It will if you use a street 90.

Minimum distance from finished back wall is 10"(using a special toilet)
From the finished side wall is 15"
I don't know your pipe lengths so I can't say if you have the room, but you can also use a st. 90 into the wye. That will gain you about 1.5"

I Guess Doug types faster then me

What is a street 90? Will the folks at Home Depot know what it is if I asked for it? Also, just so that I don't mess this up again, is this where I should cut and reinstall the new wye?

Thanks

I agree with the others--open the floor a bit more. There appears to be another T just out of site under the concrete---that might need moving to give you the space to get that drain moved.
