This is an old shower drain in the basement that I don't

That should be enough room fairly easily to throw a coupling on.

I am sure the clean out will fit right over it.

what you have to check is if it completely covers the hole you drilled.

The coupling doesn't fit down far enough without having to chisel out some cement and the clean out doesn't cover it either.

Aluminum tape on the inside.
Get some of that epoxy putty and fill the hole.
When all that shit dries, throw some silicone on the outside if you still feel worried.

>without chiseling out enough cement

What exactly is your objection to chiseling out more cement? Do it right the first time. Chisel out enough to fit a proper cleanout, keep it flush with the floor and plug that hole.

Exactly this.

It wont even take a long time and all he needs is a hammer and some steel with a sharp end if he doesn't want to buy a chisel.

Unless he has the FBI listening on his dungeon construction and has to be as quiet as possible I know of no other concerns.

get a plug, pic related, and shove it down enough that its past that hole you made before turning the screw to tighten it

stop overthinking it, just plug it with piece of rubber, there is no way the pressure in that thing will cause it to leak since there will be no place for it to go once the new concrete is there.

Literally duct tape or electrical tape over the end.

I'd chisel out enough cement around it (even an old large common screwdriver would work) then clean off the PVC stub slightly below the floor and glue the correct PVC cap on the end of the tube. Grout result flush with floor and done. No gas, no leaks from future backups, and stupidly cheap.

This. Just in case you want to use the drain later, or if a subsequent owner does.
