their own faucets or look under the counter and determine why the

Going to assume you mean the USA, but the OP could be from anywhere.

Usually, it's won't, not can't.

I'm going to cast a little blame on our education.
I don't remember the class where they explained how plumbing works
introduced us to wrenches, the fuse box, a level.

Sure, if you weren't too smart and were taking vocational training
you might have gotten some of that.

Had a plumber here once working on a bathroom remodel.
While he was here I discovered a clogged drain.
He offered to clear it.
I told him, "I'll be damned if I pay a plumber to clear a drain".
Got a really strange look.

Apparently a lot of people are not familiar with snakes.

When I had the drain cleared in a few minutes, he called his brother
(the GC) recounting the story.
