I'm Terry with Towers Murray Plumbing, here to show you how to repair the float ball assembly. Now, when repairing the float ball in the toilet, things you want to look out for is if the float ball itself is bad of if it's the mechanism inside here. Now, if the arm is broke, you'll need to replace that. The first thing you want to do is go ahead and unscrew that float ball to find out if it's full of water. Once you get it off, you'll be able to tell real quick if it's full of water. If it is, if it's got a crack, if it's full of water, you'll need to take that down and replace that. If that's not your problem, if it's inside the valve mechanism itself, you may need to replace that. Some of your replacement parts may look a little bit different but they all work the same. Once you get your new float ball, screw it back on to the rod, back into the valve, and you don't always have to remove the valve itself when you're replacing just the float ball itself. Now, the float ball is the part inside the toilet that floats up and shuts the water off. Now, when you're repairing this, it's a good thing to turn the water off first then you can find out if it's the float ball that's leaking or if it's the valve mechanism itself. And again, I'm Terry with Towers Murray Plumbing. We've showed you how to repair the float ball assembly in your toilet.
