Hello,
I'm in Virginia. I'm doing a bathroom renovation and relocating a toilet. I'm sorry I don't have pictures at this moment, just want to bounce some ideas. About 15 inches to the left of the new toilet location there is a 3" pipe that drains into the main stack. The drain is coming from the second bathroom. At the main stack there is a sanitary cross in which to the right this drain is connected and to the left the old toilet was. Since I'm relocating the toilet from the left of the stack to the right, it's easier to use the current drain coming from the other bathroom to tap the toilet. My question is how to install the sanitary Tee in this 3 inch PVC pipe without having to tear the entire drain stack. The PVC pipe is solid in place without any give. I was reading about banded no-hub couplings but got all confused. We pulled all permits and I stumbled with this forum while looking at the couplings.

What would be the best option to add this sanitary tee? or I would have to cut into the main stack and replace the cross?

Any help would be greatly appreciated.

Thanks
Gianni

you glue 6 inch pieces into the two ends of the san tee. put the metal sheilds over those pieces. then slide the rubber coupling part onto the ends. roll the open end of the rubber back like you are folding back your sleeve.
take an end to end measure and cut that much out of the exixting PVC. slide in the piece, unfold the rubber and slide the sheild over. align the san tee and tighten.

Thanks!! Is that the procedure for the Banded no-hub connector? is such allowed for Over ground installations? I was reading the VA Plumbing Code and it states that mechanical joints are not allowed above ground. No distinction for banded no-hub. I'm just assuming mechanical joints are all these "mission" type joints.

*705.14 PVC plastic. *
Joints between PVC plastic pipe or fittings shall comply with Sections
705.14.1 through 705.14.3.

*705.14.1 Mechanical joints. *
Mechanical joints on drainage pipe shall be made with an elastomeric
seal conforming to ASTM C 1173, ASTM D 3212 or CSA B602. Mechanical
joints shall not be installed in above-ground systems, unless otherwise
/approved/. Joints shall be installed in accordance with the
manufacturer’s instructions.

Thanks again for the reply!
Gianni

MA code allows them above ground with no special permission needed. i don't know about your code ???

I believe VA is under UPC which does allow shielded couplings.

Thanks to all for the information!!! I'll check with the inspector.
