This really bums me out, man. One of the drain pipes below my kitchen sink is totally loose. Here's a picture of the whole apparatus, with the obviously bad connection circled in red... And here's a closeup... Apparently the whole apparatus, including the garbage disposal, has shifted its position enough over the years to make the pipe too short to fit its connections. Can I just go to some hardware store and get a slightly longer pipe? I've never attempted a project like this before but I'm too poor to just call a plumber at the drop of every little hat that comes along, so any advice y'all may have to offer would be greatly appreciated. Thanks in advance for your tips.
