    I want to sweat PVC for my kitchen sink rather than use the plastic kits at the box stores. Bear with me while I ask what could be a silly question. The component on the left of the p-trap in the photo goes to the waste pipe. The right of the trap goes to the sink's tailpipe. My only question is: can that left piece be slightly twisted as it is? Or does it have to be aligned with the right side -- that is forming a straight line? Thanks in advance.

    You can swivel any direction you want. That's pretty common.

    Thank you, Terry. The part I had to cut out and replace (new cabinets; different configuration) worked well for 28 years. I put it in back then, which was my last significant attempt at plumbing. So I'm starting all over again! Thanks again.

    FWIW, Massachusetts has what may be some of the strictest plumbing rules in the country. Not only must the parts you use be listed on the state run parts database, nobody is legally allowed to do any plumbing anywhere, without a license.

    So, proceed at your own risk. Lots of people do, but if caught, it can get pretty nasty.

    When you cement PVC, you need to get it right the first time. With practice you can become adept at getting it right the first time on a project. But on your first project, that may be harder than you think. When you put a trap adapter at the wall and use slip tubing, you can adjust at your leisure. You can take it apart to clean. You can replace it with no problem. The slip is to be used only where it is accessible later.

    May I suggest that you consider slip brass (chromed or not) rather than slip plastic? The plastic and brass are interchangeable. It will give you an appearance upgrade. 22 gauge plated brass is common, and heavier 17 gauge is fairly easily available.
