My 110 year old house has two sewers. The newer is cast iron hub & spigot. The older is 6" clay. Both connect as I have determined from a hose test and tracking the line with a snake and a sensor.
One riser from the kitchen connects to a clay stub coming up through the basement floor slab. Part of the clay hub is broken (was packed with concrete to transition to galvanized). I installed a new riser from the kitchen to this hub and have temporarily stuck the riser into the inside of the clay hub and packed it with oakum and caluk.
Any bright ideas for a permanent installation? The ABS mechanical couplings which are designed for transition from clay will not work. Too much of the flange is missing nearly flush with the finished floor. I am considering boxing out (about coffee can size) a form and pouring 4" of mortar or grout as a curb to anchor the stub in place. This would give it a little more rigidity and prevent further damage to the clay.
