So I am repairing my cleanout because of root infiltration. The current cleanout is 4" ABS that goes from cast iron to clay. The cast iron is only at a few degree incline while the clay is closer to 15 degrees. The way the cleanout is currently installed it looks like that difference is mostly taken up in the Fernco coupler between the ABS and clay. I would like to fix all that and install a 1/32 bend in the ABS before it connects to the clay. Problem is I can't find any. Only thing I have found are CPVC 4" 1/32 bends. Anyone have a source for ABS or perhaps a different solution?
