This Part Could be Keeping your Sink from Draining. This is how you fix it 

Great video & great job! I noticed it once you showed both sinks. Bummer that they paid others who didn’t see this. 😮

I'm looking forward to the next fix!😊

Good video thank you

I own rentals. I get rid of those and replace with strainers whenever I replace faucets etc. In my experience, not many people, if any, even use stoppers in sinks. They just create support tickets.
