PVC piping for pool

Am going to work on 2" PVC. Some questions from a homeowner who has never done plumbing before of any kind other than shower faucet installation.
This is for my pool. I have 2 questions:

Q1:
I have PVC piping which is painted matte black. Will need to remove enough of it to fit a coupling. If I don't remove it I may compromise the installation and see a leak.
How to remove the paint? Safety to me is important. I don't want to breathe anything toxic.

Q2: What is the min surface area necessary to get a reliable bond? What I mean is how long along a pipe in terms of inches is necessary for me to bond a fitting. I have a section with less than one inch (maybe 3/4 inch) and I am wondering if I can get a successful bond there?

Use sandpaper, a file or a knife to scrape the paint off.
Like I mentioned in your other thread.... the paint doesn't usually stick that well.

You need a piece of pipe equivalent to the length required to slide into each fitting. That would be approx 1/2"-3/4" inside each fitting. A total stub length of 1-1/2 to 2" long. The two fittings can touch each other.

The blue illustrates the stub. It needs to be fully inside both fittings. You should install A first. Then your stub(blue) then B.

Originally we discussed splitting B but if you're asking about black paint I'm guessing you're going to be cutting the pipe somewhere by the green line and using a coupling.

You can also install a 2" union in place of the coupler.

Just be aware most two inch fittings sold by stores like Home Depot are not pressure fittings. They are drain fittings and will blow apart. The pressure fittings have a much deeper socket for the pipe.

I probably should have combined the threads but the other one is getting a little long.

Good point on the fittings Ray. I believe I mentioned getting the fittings from a pool supply store in the other thread.
