I posted about this before but didn't include pictures.

A quick recap...I am getting rid of an illegal bathroom, turning it back into a Florida room. All the drains will need to be plugged and sealed, upstream and downstream.

For example, I need to terminate this offset toilet drain. The metal flange is about 1/2" ABOVE the finished floor. I do plan to redo the tiles.





How would you terminate this? Do you make a cut through the slab, a rectangle around the flange, then break up the slab, then cut the pipe with an internal cutter, then glue in a plug, patch with concrete?

Or is there an easier way.

Packy suggested previously stuffing newspaper down the pipe, then pour concrete to seal it, so that is one of the options.

Sum, I would want a glued plug for a seal, then concrete and tile.

That means concrete demo hammer and lots of elbow grease...

isn't this the job that will have the piping removed at a future date ? the capping is just temporary ?
seeing the picture gives me another brilliant idea..
use an internal cutter, stuff newspaper down the drain and pour a quart of PVC cement into the pipe ..11 bucks and it is done.

You won't have the break any concrete. Use an inside pipe cutter to remove the flange, use a 3" rubber test plug to seal the drain, and then mortar mix, sand, glue, or any filler of your choice.

Packy, right now, I am going to terminate all drains in this bathroom. 1 toilet drain, 1 floor drain, and 1 tub drain need to be sealed and terminated. I also have a vent and a lav drain to deal with but those are easy because the vent does not protrude the roof, the last owner simply put an AAV inside the wall. So all I am going to do there is to cut the vent to about 6" above the floor, then cement a cap over it and close the wall.

However all these drains in this bath group still lead to the main drain at another bathroom. Some time in the future (2 months), I will open the slab in that bathroom (because there is a shower there that has no p-trap underneath , when I do that, I will terminate the downstream end of the pipe from this bath group. At that time all branches of that drain will be dead ends.

Back to the toilet drain. I don't see how I can use an internal cutter. It's an offset flange, don't I need to see the entire riser to use an internal cutter?

sum, the pipe doesn't need to be pretty it just needs to be cut. even if the end looks like the end of a roll of salami, you can seal it with something.
especially if its only gonna be a few months.
