    I am moving a drain pipe that used to be connected to a bathtub (I'm building a shower.) The drain pipe is cast iron and I need to connect plastic pipe to it. Can anyone tell me how I can do this?

    It's a little tough to tell from the pictues,
    You may have a hub there, that will take a pipe using a rubber fernco inside hub seal.

    This is how plastic would look into the hub.

    I hope that wasn't a load bearing toothpick in the picture, Terry!

    Here are the picures of the pipe. I believe it is all cast iron? I would be able to hammer a dent in lead, right?
    Can I cut the cast iron pipe and connect plastic? If so, where would I cut it? I'm going to move the drain about 14" to center it for the shower.
    Thank you for your help!

    If you cut the cast, cut it behind the hub.
    But first measure to see what diameter it is.
    Most new cast iron is 2-3/8"
    Some of the old stuff is 2-1/8"
    When I couple the small stuff, I use a Copper by cast coupling.

    Or, it looks like a rubber seal is stuck in the hub, if so, you may be able to pull out the last pipe.

    Toothpick? There was plenty of wood there already in that non load bearing wall. That had been done by the handyman before me.

    It is a rubber seal so when you say "pull the pipe out" is that literal? Can I just yank it out? I did tug on it a bit, but was afraid to really pull it for fear of pulling out everything, the larger pipe and all (possible?) I've never touched a plumbing pipe before in my life so this is all new to me. I'm about as new as they come to DIY projects but so far so good.

    Yes, you may be able to muscle it out.
