What actually happens is the plumber says “it’s probably X but I need to check out the sink.” You can try your luck on X but more likely they make a house call and you’re billed for a house call even if you insist on turning the wrench yourself. The next time you have an issue, you can try the same fix again, but if it has a different cause you’re calling the plumber again.
As I clarified above, don’t do remote instruction! This is definitely not what I meant. I meant “have the plumber come by in person, show you how to solve the problem in person, then have him get paid for his time and be happy and leave”.
