    We found a 4-inch uncapped cast iron clean-out behind wallpanelling in our basement (surprise!) - it is almost flush with the cement floor - and within a couple inches from the foundation wall leaving no room to install a screw plug. We don't want to leave the clean-out open when we repair the wall nor do we want to work with oakum/lead needed for cast iron fittings. Any suggestions on how to cap it? Can you use a low-expansion foam caulking/sealant?

    There are a few ways to cap it but the last thing you want to do is hide that in a wall. If your sewer ever clogs the drain cleaner will want access to it or the job could that longer and get expensive... Very expensive!

    Thanks for the advice - I agree - no hiding of cleanouts or shut-off valves. We also found a water shut-off valve in the same wall - so we will be framing around them and putting a removable panel.

    Any suggestions for capping?

    It depends on what you have to cap.
    Is it threaded? Can you post a picture?

    Measure the opening and go to your local hardware or home dumpster and they will point you to a nice expanding rubber and plastic type plug.

    If threads are available I would use a threaded one as a matter of preference.

    If there is a bell on this cast iron pipe they make a rubber gasket you can use instead of lead and oakum. The brand name of the rubber gasket here is a TY Seal and then you can insert a cast iron clean out ferrule with a clean out plug. Now if the cast iron pipe was cut flush with the floor with out a hub, then your only option is a expansion plug also known as Test Plugs or even dollar plugs. Well good luck with your project. I hope this helps.
