Thread: Need a plug for a basement floor drain

  1. #1

    Default Need a plug for a basement floor drain

    I have a cast iron drain in the basement floor that has a hole for running a snake down the line. The hole is a bit over 1-1/2" and not threaded. I'm thinking of using a cone made of rubber or cork to plug it when not needed. Any ideas on where to get or what the part is called?

    I guess if you don't mind the large thread and nut in the way you could use this:

    Is that what we called a test plug?

    Default hole

    My question would be why, if it is really a cleanout point, DOESN'T it have a thread in it?

    The drain is 50 years old. It might have been threaded at one time. The normal water flow is below the clean out.

    Let me see if I can find a picture...

    That might work. The only issue I can think of would be the ears on the nut. Could replace it with a standard nut. Thanks!

    I haven't been able to find a good picture. It is called a floor drain with concealed cleanout. This picture is somewhat similar except: 1) Trap is about 30 feet to the right and 2) pipe continues to left of drain.

    Here in Illinois it is pretty common for the clean out in a basement not to have threads in it, they install a expansion plug instead. They do make expansion plugs that are flush at the top so not to be a trip hazard. They also make a plug we call a "Dickie" plug also known as a cone plug has a rubber insert with coarse threads that inserts into the pipe and the plug which is cone shaped as it threads the tapper pushes the rubber against the wall for a tighter seal.

    Default drain

    The concealed cleanout would be completely useless, and redundant, unless the trap was not only at the drain, but integral with it.
