There are some really smart people out there. I'm thinking about people who improve a product right now.
This was bright on by losing my wedding ring down the bathroom sink drain.
I was terribly worried.
It was just after I got out of the shower. My contacts were out and my glasses were upstairs. Reaching for my watch and ring, I pushed my ring into the sink and was embarrassingly bad in the attempt to snatch it from the sink before it fell down the drain.
Panic set in. I ran up the stairs two at a time. Glasses on. Down the stairs. Grab some towels. Pull everything out from inside the cabinet. Throw the towels down to catch the water. Then I saw that the drain pipe was PVC. I was able to open the three nuts, remove the pipe, and have minimal water come out. All by hand. (Obviously, that would be different if the sink were clogged.)
What a terrific innovation-a catch in the system. While it seems obvious, there was a time when it didn't exist.
So here's to the person who figured out that plumbing innovation. Cheers!
