Bob - Those plugs are not the correct long term solution.

So, this is a basement floor cleanout in cast iron. The plug was originally
cast iron or bronze and may have been tapered. try a plumbing supply house
and ask them. You may need a new threaded section if you cant find the cap.
See if anything here looks familiar.

Thank you Speedy Jim.

Heres my problem.

There use to be a 4in screw in cap on my sewer line in my basement. One
time it rained like crazy and the water backed out. It turns out the
pipes threads are stipped so the cap was just sitting on top. When the
water backed up it just lifted off and my basement filled quickly.

So I purchased the below item from home depot.

This at it tightest setting does not seal the drain. Its like the very
top of it fits over the drain hole but the rubber in the middle does not
expand enough to grasp the pipe. I was wondering what else I could try.
May be the homedepot version is a piece of poo and another brand might
work better? The drain is metal and under the basement floor. Only the
part with the threads is showing above ground.

I was going to try this...

Please let me know what you think.

Thanks again.

Thanks



A cap goes over the end of a pipe. If plastic,
you can get a glue-on cap. Or a rubber cap with stainless band.
