How do I finish this drain?

This is a backup drain to sit below a washing machine in a second floor bathroom, should a leak or overflow happen. How do I finish this off with minimal cutting of the floor? PVC is currently flush to the top of the tile floor.

New to plumbing, confused about clean pipe cuts

I’m still new to plumbing stuff. Just trying to fix small things at home, nothing serious. As of recent, I had to replace a small section of pipe under my sink. I watched videos and they made it look very easy.

My issue is cutting the pipe clean.

I used a manual cutter first. It worked but the cut was not very smooth. It had small rough edges and I think that’s why I got a tiny leak when I joined it back.

Then I saw people talking about cordless tube cutters (SPU). I don’t fully understand if it makes a big difference or if it’s just for professionals.

I almost ordered one online. Even checked Alibaba because price was cheaper there, but I got confused reading reviews. Some people said it works perfect, some said it stops working after few uses. So I didn’t buy yet.

My questions are, Do I really need a powered cutter for small home jobs? Or is my problem just bad technique? Should I also be sanding the pipe after cutting?

Also, how do you know when the cut is “good enough”?

I don’t want to keep guessing and causing more leaks 😅

Thanks in advance, I really appreciate any simple explanation.

I am unable to stop this leak no matter how hard I tighten, or clean the fittings, and the washer is tightly packed correctly

Tile and walls came out 3.5 inches thick. I need help

Long story short I forgot to change the stub outs. Left the compression shut off fitting on 1/2 inches thick copper pipes from old sink. The wall was rocked, and the thickest wire mesh mortar wall on earth was installed with this tile on top and when I got home, I realized this won’t work. I wish the tile setter would have said the walls were going to end up so big. Anyhow, this faces my back porch, aside from ripping off the siding and going at this from the back, are there any easier options from where we are now?

Paper towel clog - Coincidence or sabotage?

We had a plumber fix a supply issue, but to get to it they disassembled (the reassembled) the kitchen sink drain. A few hours later the sink backed up (it hadn't really been used yet). I disassembled the section the plumber removed and found the clog: an entire, intact paper towel.

The only natural path to that part of pipe is through the garage disposal. I have kids and we just had guests over, so I would believe that one of them got a paper towel into the sink and it got into the garbage disposal. However, wouldn't the paper towel have stopped there? I find it hard to believe that it made it intact past the disposal mechanism.

Is it possible for a paper towel to make that journey, or more likely that the plumber jammed it in there? (Cynically to get us to call him again, but more generously to perhaps stop it from dripping while he was working or something?)
