Tile over floor drain question?

[Richard]

A bit misleading as it's not really a drain.

Setup: When building, we ended up moving a wall but the right hand and left hand never heard about it so someone plumbed for a vertical drain (inside the now missing wall).

Here it is. It's TOTALLY useless and will be in "the middle" (not really) of the room.

We're going to be laying regular ceramic tile in this room this coming tuesday.

I've had this temporary plug in there for years. One thing the picture does NOT show you is the plug is recessed. Doesn't matter much, but it is in fact, recessed.

Ok, question... went to HD and found a plug. This thing is about as flimsy as all get out HOWEVER, it seems it's exactly what I need to cap this off.

I can't put a regular cap on it because it's not recessed THAT much.

The tile guy says he'll just mud over the hole and forget about it.

Knowing that rubber can deteriorate over time, I'm not sure I want to leave that possilbity open, even though it will have mud and tile over it.

So, here's the question for the experts, should I just leave the plug in there as pictured, or remove it and glue in the thin wimpy plug on the right?

(seems to me that it wouldn't take a LOT of pressure to break through it either however there should't be any pressure once the tile is installed.

Thoughts?

You can flip the bolt on the expandable rubber plug that is in there now. Put the wing nut on the bottom, carraige bolt head on top , pre-tighten the plug to expand it, then push it into the drain with a hammer.



They make those plugs with plastic top and bottom plates also. The metal plates will eventually rot but it should take many years.

It should be fine with any of those plugs but if you are really worried you could chip the concrete around the pipe and glue in a regular cap.
