I'm running a new PVC drain line (for a kitchen sink) and would like to
tie it into some existing cast-iron drain pipe in my basement. After
much consideration, I'm thinking that the easiest approach, if
possible, would be to extend the existing pipe at the cleanout.
However, never having worked with cast iron pipe before, I'm wondering
about the best way to do this. For reference, I've put a few pictures
of the existing drain pipe at http://userpages.umbc.edu/~paulr/usenet .
The pipe diameter is 6", and the cleanout appears to be a standard
bell with a threadded ferrule caulked in place to accept the cleanout
plug. Is this how most cast iron cleanouts are put together? If so,
Would it be possible to pry out the (presumably lead) caulk, remove
the ferrule and insert a Fernco donut fitting to accept new PVC pipe?
If not, I suppose I could adapt the new pipe to the threads for the
cleanout plug, although I imagine that would be less desirable. In either
case, I want to add just enough pipe to glue on a PVC "Y" fitting to
accept a new 2" drain stack along with a new cleanout plug. Does this
Thanks for any thoughts,
