knob

I had this rental cleaned before we moved in on June 1. When we moved in, the knobs were missing from old stove. They had been there before. I couldn't find them anywhere, so I bought and installed new ones (upper right in photo). Then, the kitchen sink was backed up. I used draino, but it kept getting backed up. I used the plunger, and up popped this knob (upper left). I had Roto Rooter come, and he found the other three, somewhere down in the drain.
