| You have a couple of options here -- You can cut the hub off of the old cast iron pipe and make the transition with a 'no-hub band', but this is hit and miss at best, different weights of hub and spigot pipe have been used throughout the years, and the outside diameter will likely be either bigger or smaller, more likely smaller, than today's no'hub cast iron pipe, which means the stainless band will be distorted upon tightening.
Fernco 'tye-seals' are another option, but will require a great deal of brute force.
If it were me, I'd use oakum and lead wool to make the transition. |
