Thanks. Um, my original question on this thread was how to connect a shower drain to a cast iron pipe. Everyone said I had to switch to plastic (at least I think that's what I was told). I just looked at Zurn.com and saw two cast iron shower drains that seem to have a "no hub" option.
Model FD2252 and Model FD2254
On JohnBridge, there was an old thread about a "jiffy gasket" or some such thing that slips over the cast iron pipe to seal the shower drain on.
So, if anyone here knows, I'll return to a variation on my original question...how do these cast iron drains attach to the cast iron pipe? Do they all use the gasket described on JohnBridge?
And thanks, I have watched the Kerdi videos, etc. But if I don't have to use a plastic drain, I think I'd rather not.
It's also okay if you all don't know the answers to my questions. I will go back to the plumbing supply place (the same ones who were able to tell me in great detail how to weld a brass flange onto a lead toilet bend and order the correct one for me). It's just that it's after 6 and they are closed now.
I will document all of these things and post here for future people like me who may be confused by the seemingly arcane NYC plumbing practices. We are so old school here.
