• 00:00 Hey guys chrisfix here and today I'm going to teach you how to replace a bathroom sink faucet and bathroom sink drain using common hand tools that way you guys can get this job done at home yourself and save a ton of money. Now the national average for a plumber to come out and do this is 400 and this kit right here which comes with everything you need cost me around 50. I'll be sure to link this kit and the tools. I'm using in the description. So you can easily find them and get the job done yourself. So we're saving around 350 by doing it ourselves and in this case the reason why I need to do this is because you could see. This faucet has seen better days. It is all corroded and I actually did try polishing it out. You can see the top right here but the plating is so thin it just goes down to the metal underneath same thing with our drain. Not only that underneath here is so corroded from this being so old that it is leaking so let's go underneath and let me show you all right so. Let's clean this out real quick so we can get under the sink good so now that we have access under the sink. Let's turn the water on so you can see how bad this is and that's leaking pretty bad. I mean look at that leak even though we only ran the water for a few seconds. It's pouring out so it's leaking from this rod right here which is the pivot rod which opens and closes the drain in the sink. So in addition to replacing the faucet. We're also going to be replacing this pipe here which comes with the kit so let's get right to it. The first thing we need to do is close.

• 01:23 The hot water and cold water supply valves that way. There's no water going to the faucet and these you want to turn clockwise so tighten them down and as you tighten it shuts the water off and when you're shutting these off don't over tighten them just turn them until they're snug. Just like that. Next we want to turn on both the hot and cold water at the faucet to make sure that the water is off and with the water off. We're going to go back underneath and disconnect. This old faucet from the sink so first we need to remove both supply lines that's the hot water supply and that's the cold water supply and before you loosen. These up get some type of container or towel anything to catch the residual water that's left in these lines so with the catch can in place. We're using an adjustable wrench for this entire job which is convenient so break loose the nut on the line and then you could unscrew it the rest of the way by hand and you can see. This is why you have to have a catch can look at all that water okay so now that this is disconnected. Let's break loose. The other side good and we'll remove this side the rest of the way by hand and set that off to the side as well. Next at the bottom of the sink where the faucet and the sink meet we need to remove the two hoses from the faucet. So use your adjustable wrench and break that nut loose and remove it the rest of the way by hand and now the cold water hose is removed next there's a screw-on washer that needs to be removed and this holds the faucet in place so let's get that removed completely. Then let's remove the clevis strap that way we could pull the lift rod out of the faucet like that and then we could break loose the hot water line and remove it the rest of the way and finally we just need to remove this last screw-on washer.

• 02:52 All the way and now our faucet is loose and could be removed so out with the old and in with the new. But before we install our new faucet we need to clean the old gasket off the sink so let's grab some soapy water and spray down the hard to remove gasket material and then grab a plastic scraper and remove the rest of the gasket that's really stuck on there and please don't use a metal scraper here because you're just going to scratch up your sink. The plastic works great because it doesn't scratch the sink. Here's a before and after okay so with a clean surface get your new gasket and lay it down over. The holes then grab your new faucet and carefully line it up. So it matches the gasket be sure you match the gasket even around the entire faucet. That way. We don't get any water intrusion underneath the faucet and it looks good and check it out that looks so good especially compared to the old one. Not only is it nice because it's not corroded. But it's a lot more modern than the old one. The old one's pretty old school so that is looking absolutely beautiful. We are done up here.

• 03:51 Let's go underneath tighten that down and get the hoses connected so we can run the water so first let's secure. The faucet with these washer nuts so tighten down each one by hand and once they're both snug you want to work back and forth snugging each one up that way. The faucet gets tightened down evenly all right so with the nuts tightened down. This is secured so this won't budge. Also. This gasket is seated against the surface of our sink so we won't get any leaks so that's in place. Now what we need to do is install our water lines. You can either use the new ones that came with it or reuse your old ones whatever you want. I'm going to use the new one so everything's brand new so let's go underneath and let's tighten. This down actually real quick if you look inside the end of the hose you can see there is a rubber gasket. I want to point this out because that means we don't need to use anything on the threads we don't need to use tape. We don't need to use any type of compound to prevent any leaks. This gasket will seal it up so let's just tighten down the nut by hand and then grab your adjustable wrench and snug it up good alright. So our new line is a lot longer than the old one and to make it fit without any kinks. What we're gonna do is we're gonna loop it around like this and tighten it down so hand tighten the nut. All the way and snug it up with your adjustable wrench and no need to over tighten. These just tighten it so it's snug now. We can get the hot water hose on and you can see. The hoses are actually color coded blue for the cold and red for the hot and then we could snug the nut down good do that little loop with the hose so it fits and there's no kinks and then tighten down. The other end of the hose to the valve and snug it up like so all right so our hoses are tightened down.

• 05:27 They are nice and neat and they are in so we have completely finished installing our faucet. Now all you would do is turn those on and check for leaks. But we're gonna have a giant leak because our drain is leaking. So we need to replace this drain first. It's super easy to do let me show you how all we need to do to remove. This is disconnect the nut up here holding it into the sink and then there's a slip nut right here that needs to be loosened and then another slip nut right here and the p-trap will come out and we'll be able to remove this. So let's start by removing this nut up here using a large tongue and groove pliers and a tongue and groove pliers is designed so the jaw opens up pretty wide and it accommodates large fasteners like this okay so with that jam nut loose. This whole drain is loose but in order to remove this what we need to do next is remove the p-trap so grab. A catch can because there's gonna be water in the p-trap. Then we can remove this nut up here by hand and the nut down here by hand and let's give this a pull good and the p-trap is removed so this is actually a pretty important part to your draining system your sewer system. This is called a p-trap because what it does is it traps water in here this right here is your sewer line so if we didn't have a p-trap and this just went straight out into your drain. You would get gases from your sewer line from the sewer in the street into your house. It would smell horrible but what this does is it creates a trap for water to sit down here and basically block any gases from your sewer getting into your house. Also this is the first thing to clog all the dirt hair anything that collects in here is going to collect right here and not deep into your sewer line which is a lot harder to unclog so if your drain drains slowly just take the p-trap off and clean it out. In this case. Our p-trap is already clean. There's nothing in here. Our drain drains at the proper speed but if your drain doesn't drain quickly.

• 07:15 This is probably clogged up take it apart clean it out put it back together and you're good to go so. Let's slide. This nut off the drain pipe and now to remove this we need to unscrew it like this. But the problem is as we're unscrewing this. The drain in the sink is spinning as well. So we aren't actually unscrewing anything so to stop this from spinning. I'm going to press my pliers into the drain and create some resistance and now when we spin the pipe we're actually unscrewing it. Oh and look at that that is disgusting and the same thing at the sink look at all this crud. In here I'm glad. I'm wearing gloves okay so clean this gunk out and I can tell you you guys are lucky. You can't smell this through the screen. So the emergency drain drains straight down right into a hole that I could feel with my finger right here. But you're not gonna be able to see. I do have a mirror and here's a better look. You can see the hole in the mirror which is right where my finger is right there and to better visualize this when we do the install. I'm gonna just put that piece of tape right there and the reason why that hole is important is because our new drain has a hole right. There you see that hole in that so when this goes in we have to align that hole with this hole so that our emergency drain could drain the water even when that's completely closed. So here we go you can see. Our drain hole is right up there where my thumb is keeping it straight towards the hole and that's all there is to it now that hole's aligned with our emergency drain hole so with the new drain in place.

• 08:42 Let's get the new rubber gasket on being sure the wider end of the gasket is going up against the sink. Like this now we can install this nut so thread it on and get it nice and tight up against that gasket. This only needs to be hand tightened but make sure it's snug like that. Now all that's left is installing the p-trap so grab. The top nut and washer and we'll put the nut on first and when installing the washer there's a flat side of the washer and then there's a rounded or curved side of the washer. The flat side should go up and press against the nut like that then just get the p-trap in place and we'll tighten down the back nut. So it's snug just like that and then let's tighten down that top nut so it's snug and the gasket's gonna seat against that nut. That way there's no leaks so with the p-trap installed. Finally we could open up the valves for the cold water and for the hot water all right so everything has been reconnected. Our water is on and we have a paper towel here so we could easily spot any leaks so now moment of truth. Let's try it out and look at how good this looks. Let's see what we got here hot water cold water. It's looking good. We could stop it from uh draining there. That's working it's draining out and let's see if we have any leaks and not one drip at all beautiful so that is exactly how you replace a leaking faucet and drain super easy to do.
