I usually don't tackle plumbing jobs on my own but I'm going to try replacing my bathroom vanity. It looks like something I can handle from the research I've done. However, I noticed something a little different about how the current waste pipe is installed. Here's a picture to help explain my concern. The grey waste pipe was installed directly into to PVC going into the p-trap. You can see where the top of pvc is expanded to accept the gray pipe. What's the best to go about installing the new waste pipe into the existing p-trap? I think the new sink will be the same height as the old one. I measured from the bottom/outside of sink drain to floor and measurements are the same.
Thanks.
Thanks.
