    need ot know how to plug older floor drain in concrete slab floor

    round deep dish hair under 2.5" diameter drain hole in floor
    no threads or anything, and its made of steel or cast iron

    meant ot have iron or steel bubble cap on top but thats not enough to prevent water backup and basement filling up when it rains hard and storm sewers back up water level above floor drain level which happend often here since storms and sewers are not separate, this is an old town, old red brick sewers manholes here

    how can i seal off a floor drain like this and still be able to remove it to drain water now and then ?

    basement would be nice and drya nd clean if it werent for this

    what do i have to do ?

    do i have to bust of concrete around it and hook on to the new plastic 4" below and put in a threaded cap or what ?

    thanks for anything

    They make a compression plug for them. Its a rubber disk inbetween 2 steel plates with a wingnut on top. As you tighten the nut the plates compress and expand the rubber to seal the drain. You should be able to buy one at any local hardware store.

    Its most likely cast iron. Is the hub of the pipe sticking out, or does it look like a regular piece of pipe? Hub is wider so that another pice of pipe can be slid inside the original. If the hub is there, you will have to use a compression plug, or a blow up ball plug. If its just the regular end of the pipe, go to the plumbing store and ask for a "(whatever inch the pipe is) FERNCO CAP". The is a thick rubber cap secured by a hose clamp, used frequently for cast iron.
