Do you have any recommendations for repairing broken 2" pvc pipe sink drain without digging up the cement floor? The right-hand side of the break is flush with the floor.

What I was able to find requires access to both sides of the break to insert coupling over-top. Hoping I do not need to break up the floor which is beyond my comfort zone.

Thanks!

IMO, breaking the floor is the only option.

Research PVC bell reducing couplings.

Look for PVC inside coupling.

Look for PVC inside coupling.

A inside coupling is not a good choice for a drain
It restricts the size and will cause blockage.

rjniles is correct:
1. Drain line can increase in diameter as it moves forward, but it cannot decrease.
2. The OP will need to cut the pipe a straight cut, set a coupling and make the repair.
3. To do that, he would need to cut the concrete.
4. To cut the concrete in a square around the pipe, get a diamond saw blade, then use a cold chisel and a hammer. Them remove the broken concrete pieces for a clean access.

5. Cross your fingers and hope the concrete demo doesn't cause cracking of the pipe further down. :vs_laugh:

OP, how exactly did this pipe crack like that?
