I'm about to flatten my basement floor which has a significant slope at the drain. I will be keeping the drain but need to raise it about 2 1/2" inches to meet the new level. However upon inspection I noticed that it is just a 4" hole in the concrete that leads to a clay pipe/elbow. The slab is roughly 5" thick at this point and there is also a strange 3/4" plastic pipe that goes under the slab and into this drain from a nearby sink drain.
What are my options? Do I have to smash up the concrete and convert from clay to ABS/PVC with a fernco coupler or can I just simply insert a 4" pipe into the clay hub?
The clay pipe is not damaged. Is there a way to sleeve a pvc/abs pipe into the clay?
If that and pipe is going to the clay pipe you need to place it all with abs
Only if it's sanitary drainage clay pipe is for storm water
It is storm water drain. I was hoping to just sleeve the concrete with an abs pipe and cap with drain cover.
