How to fix a ceramic faucet with a ceramic disk replacement cartridge. Kitchen sink faucet, pretty standard, we have one here, a pull-out spray, most houses have them now. Just for the sake of time, I've already shut the water off to this faucet, so the first thing to do is test it to make sure that the water is off. Test the hot, and test the cold. With this faucet, what we're looking to do is change the ceramic disk, which is going to be underneath the handle, and so I'm going to walk you through that process right now.

So you want to take the spout, turn it off to the side, take the handle, lift it straight up. This nut right here, we're looking to take this handle off, some faucets have an allen-wrench set screw in the back, some faucets just pull straight off, this one here has a little decorative red and blue rubber stopper, and if you take it out with your fingers, set it off to the side. So, in order to take this handle off, you have to use a very small allen-wrench. This allen-wrench size is about 1/8th of an inch, and you insert it into that hole, back off the screw, not all the way, you don't need to, and it lifts off, set it off to the side. Now you're going to see this little plastic piece, this is decorative. This little decorative piece, you don't want to put a tool on, its usually just hand-tight, get a good grip, back it off. Now there's a glass piece that holds in this cartridge, sits right on top. So you want to take your time and you want to back off this brass piece, and you want to use your channel locks (xx xx xx) and you want to back it out. Then set your hardware off to the side, now the cartridges will move straight up. Take notice that the cartridge has a couple of little plastic protrusions in the back. This little red piece, these are the O-rings, this is usually what leaks, and if it does, quite simply you just take a ceramic cartridge and you put a new one in. We happen to have one ready to go, so, this ceramic cartridge goes right back in the same way it came out, and we're looking to line up these little protrusions in the back of the faucet. You take it, drop it back in, make sure its nice and tight and not moving anywhere. Take your channel-lock pliers, tighten it down until its firm. Reverse the procedure, take your decorative chrome piece, put that down, and what I'd like to do is just put the handle back on for now. I want to turn the water on, run the faucet, make sure its not leaking anymore, make sure nothing's hidden, so I don't have to do it twice.

Okay the water's back on, now we're going to test it out, appears to be working well. So now I can take my allen-wrench, put it back in. And that's how you fix a ceramic disk faucet."
