I think that's a clean out so I probably wouldn't bury it under a floating floor.

Agree that you should not cover that. It is there for a reason, and if you ever need access to it you will cause a lot of damage to your floor. I can think of a couple of alternatives. Perhaps someone smarter than me can tell you better. See if a plumber could cut the pipe so that it is below the floor. Have said plumber create a lip of some kind, cut a round piece of 1/2" plywood and a corresponding piece of floor. Glue the floor to the plywood then put the "plug" over the hole. That way you can access the pipe if you ever need it and it won't be a trip hazard.

Just assuming it's a clean out or drain and I wouldn't cover it.

You can use self leveling compound if you want to take out any inconsistencies in the concrete floor, but don't cover the pipe.

Lay the flooring down and leave access to the pipe. In the past I've made little access panels from the flooring itself. This way you get consistency and you can hide it while still having access if needed.

Don't cover the drain. You also can't have a hump in the subfloor under vinyl plank. The box usually says something like 1/8" dip or hump over 8' max. Else it pulls apart at the seams

This is a brilliant idea. If we can cut the pipe to be recessed below grade, we'll definitely do this!!

Plumber here - I have my doubts that is a cleanout, but rather instead an abandoned toilet without a flange. You can confirm by pulling off that knockout cap and look down, if it turns a corner a few inches down, its a toilet. If so - get an inside pipe cutter, and inside test plug. Cut the pipe off flush with the concrete, put the test plug in a couple inches down, use a chipping hammer to level the lip around the pipe, then cap with concrete.

I would not cover it. Maybe cut around it and paint it the same color or something close in color. LVP is a great product great choice! Need any pointers - https://youtu.be/_G7fiiNxtfU

Youre a saint! Ill check it out, thank you so much. But dont cleanouts turn a few inches down too? In all the videos ive seen the cleanouts turn to a 45 degree a few inches down

All depends. Do you know if you have a clean-out elsewhere? Generally they're very close to where the main drain leaves the house, not the middle of a floor. Is there a smaller drain nearby? If so you've got an abandoned toilet & shower. If you have no idea, I'd err on the side of caution and leave some access to this. I've seen cleanouts go straight down, Tee, Y, or take an immediate 45º. Check your utility room for a big drain with a Y shaped pipe with a threaded cap on it. Honestly I doubt they'd put the only cleanout in the middle of a floor.

It could be an abandoned toilet or it could be a poorly placed clean out. Something I learned as a long time DIYer is there is a time to consult with a pro. I would have a plumber look at it before making a decision.

You have two options: cut a hole in your LVP for the pipe/cap to sit in or cut and cap the pipe below the concrete. Screeding out concrete in a radius around that pipe will require a lot of work and skill. Most LVT installations require fairly flat floors; to float out that bump would mean grading out a large area around that pipe.

Thanks for the input. The bump is rather sudden, and the floor is level everywhere else, so i think im going to cut and cap the pipe and shave a bit of the concrete
