Get the leak in my bathroom fixed

I had to order a hose (I call it a hose, but they called it a supply line) from Lowes and pick it up. I know one end of the hose is right, but I can’t tell if the other end is right because it goes up into a tube and I can’t see where it connects. I tried to disconnect the defective hose, but I can only unscrew it from the end that doesn’t go up in the tube. The plumber had said to call him to come out to install the new one, but I don’t want to call him unless I know I have the right hose. I freakin’ hate this. He should have taken care of it instead of having ME try to find the right part.

That’s why I don’t have wood floors, either… the contractor I was going to hire told me to go pick out and buy the materials and he would install them. If I’m not going to get full service, screw it.

The plumber did a great job on the kitchen plumbing that was way screwed up, though. *knock on wood*

The plumber is here because I have a massive leak under the kitchen sink that couldn’t be ignored, so I had him look at the bathroom leak, too. He said I just need to replace the hose, so I ordered one from Lowes (He said if he did it, he’d have to charge me a markup, so it’s cheaper if I do it. Nice!). I can pick it up later and have hot water in my bathroom sink again for the winter.
