I'm James with JNC Home Repair. Today I'm going to show you how to repair a step-type faucet. The tub that we are using in this shoot today, doesn't have this type of faucet but I'm going to go ahead and show you how to repair one anyway. They're pretty common usually you will see them like this. They'll be a hot, they'll be a diverter valve that controls the water flow from here to the showerhead and then there will be a cold valve. All three of these valves are almost identical. The hot and the cold are identical. The diverter valve is jut a little bit different and just on the inside. But I'm going to go ahead and show you how to remove it and then you'll know how to do this. The first thing you are going to need you are going to need a flat head screwdriver and what you are going to need to do is you are going to need to pop this little cap out. This is the hot one by the way but either way it is the same way, pop that little cap out and then you are going to need a Philip's Head Screwdriver, flip this around, and you are actually going to remove the knob. Once you have got this screw out this knob is going to pop right off just like that and that is what is going to be exposed coming out of the tile. It is going to look just like that. Now most of these usually have a chrome or whatever type of faucet it is, it will have a collar that fits up flush on the tile that covers up this valve. All that thing does is it just screws off, counterclockwise, you know take it off to the left and tighten to the right. So what you are going to do is you are going to remove that collar that is there that is covering this up and you are going to pull it off and you are going to be exposed with this valve that is exactly what you are going to see, just like that. Now the best way to get these off, usually this part right here where the socket fits, usually it is counter sunk back up into the tile so you can't reach it. You can't just, the way it looks right now you could just put a pair of channel locks on it or a crescent wrench and you could just be able to break it loose and the whole valve will come out. But most of the time this is offset and it is sunk inside the tile s what you are going to need is you are going to need a deep socket so you can actually slide the socket over the valve and it will fit right up on the nut just like so and now you have got a good grip on it and once you have got your socket on your valve like that you take a pair of channel locks, clamp it on to your socket just like so and break it loose. Go to the lefty loosey, righty tighty. So left break it loose, once you have got it loose, you remove it, pull it out and this is what a shower valve looks like. Just like so and the best way to rebuild it is what happens is when it starts leaking is that little rubber washer right there needs to be replaced and this little rubber washer right here needs to be replaced and this actually comes out and there is a rubber washer inside there as well. They sell these repair kits at your local hardware store. You just need to figure out what type of valve you have, match it, take it to the hardware store with you and match it up and replace it. You can either replace the valve as a whole, it has already got all the new gaskets in it. Or if you choose to repair the valve yourself, installation is opposite of the removal. You just put the valve back in, make sure all your gaskets are there, all your washers are there. Make sure you put teflon tape or some liquid teflon on your threads here, run it in, put it back in your valve, tighten it back up with your socket and your channel locks. Tighten it up back there and get it back in. You may want to put teflon tape on these threads as well and get that back in there. Once you put your collar back on you will be able to get this thing snugged back up against the tile again and then you just put your handle back on, put your screw back in, just like so. Make sure your valve is in the closed position, which is closed, take your cap, pop your cap in and you're done.
