How to Replace a Toilet Water Supply Line
As I’ve already mentioned, you want to replace your supply line if it’s one of the older kind which can crimp and break. Or if it’s in any way not working properly. So what you’ll want to do is shut off the water on the supply valve and flush and drain your tank. And you can put a towel down on the bottom to get some of the excess water out.

And once you’ve done that, it’s really straightforward. All you’re going to do is take a crescent wrench and loosen the nut that holds the supply line in place onto the supply valve and then you can probably just do it by hand if it has a plastic nut at the top. But loosen that one by hand and really that’s all there is to it. You just do the opposite and reverse to put the new one back on.
