I want to start with the reasoning behind changing my bathroom faucet. When I first bought this place the faucets worked fine. I just didn't really like the look too much. It was really hard to get a cup or a bottle underneath too. If I wanted to fill up some water and I really wanted to change it with something more modern looking. Also. I think it is one of the best and most inexpensive changes you can make to your bathroom or kitchen.

  • 00:46 You're going to want a rag a bucket a wrench some pliers and the faucet itself as well as some teflon for connecting the water lines so here's my faucet. As you can see. We have the hot and the cold water there at the bottom and this base plate that covers the two extra holes. So this is really key for going from three holes to one hole in your sink. So we're gonna start off by connecting the water lines mine are color coded ones blue and one's red for hot and cold water and now we're going to pay attention to which one corresponds to which we can see here. The red hole is on the right and the blue holes on the left and we're going to go ahead and connect those. I didn't use any teflon for this stage. I've done this once before and mine's holding up fine without it. And I didn't think I needed it. But if I do have some sort of leak. I can go back and add it there and then. I'm using my wrench to really tighten up that connection right.

  • 01:44 There put it all in and then I slide the base plate to the bottom and then our faucet is assembled. Next step is to clear out the sink space so. I'm removing everything that is under my sink so that I have more room to work with and there might be a little bit of water dripping so. I don't want any of that getting wet I place my bucket and rag at the bottom and my faucet up top. So everything is easily accessible for me. I'm also grabbing my 360 camera for this project. So I can bring you guys along under the sink as I work on it and now our whole setup is finished. So we can start by turning off the water of our faucet we do that by spinning the water count or clockwise to shut it all the way off yours might differ but we can go ahead and test so after I switch those off. I can see that there's no longer any water coming up to the faucet so that means we're ready to start removing the water lines so we're going to start off by grabbing our wrench and unscrewing all the nuts. This can be a little tricky if your sink is hard to get to. But I was able to manage with mine quite easily. After we've loosened all the water lines up.

  • 03:07 We can go ahead and remove the drain plug too and really move removing everything necessary so that we can remove the faucet. My faucet requires a hex allen key to remove the top part yours will probably be different but this is the way mine is. It's a little bit older. So it is a little bit more complicated but then I go ahead and remove the handles. They can be pretty tough because you know these haven't been touched in over 10 years. But I was able to squeeze it out with a little bit of elbow grease and I've just been going ahead and placing all the parts in the bucket that I have at the bottom now that those are out of the way I'm going to remove the water lines. This is the part where water can drip down so watch out. My water lines are not flexible so it is kind of tricky to get them out. So. I had to do a little muscling action here to to really yank them out. But I was able to get it off and then we saw quite a bit of water drip down right there. That's just water that is in the water line right now so there's no water running uh now. It's completely dry from this point forward. Now with the water lines out of the way we can go back to the top and remove.

  • 04:27 The rest of the faucet. Mine has these little clips that keep everything in space and they are an absolute pain to remove. I had to do this with my other bathroom and it was quite tough but now. I know this time around so. I just use a chisel and a hammer to to get the little rings off and once those are off everything just drops down. There we go so now we have the three holes exposed and ready for the new faucet. But this is our last opportunity to really clean. So we want to make sure to remove any grime or anything like that because it's the last opportunity we got to to clean here. So I'm going to go ahead with some rubbing alcohol and try to rub off all the grime and dirt that has built up over the years. Now. It's all clean and ready for the new faucet.

  • 05:20 So we're gonna start off by just sliding the water lines down and then the rest of the faucet and next we're going to get to the bottom and screw in the faucet to secure it in place. Mine has this little plastic piece that screws into the top bit and that's what really holds it in place and prevents it from spinning around. If you have someone else to hold the top part. It can be helpful but I was able to reach the top and the bottom at the same time to really get a tight squeeze on it and make sure it's not moving anywhere up. Next. We're connecting the water lines and this is really where you want to use your teflon. We want to make sure that the water line has no leak so we're going to add some teflon around the uh. The mouth of the of the water of the of the hot and cold water and then we'll be ready to connect the water lines to the faucet. So just a little bit of teflon goes there. And then we can start screwing it in. I just first screw in by hand and then later I'm going to come back and tighten it up with the pla oh with a wrench. So at this point. I grabbed my wrench and I'm just gonna tighten. The nuts make sure we have a tight squeeze because we really don't want any leaks here so that side is tightened up. Now we can move on to the other side and make sure that it is really tight as well and it is and at this point.

  • 06:53 Our water lines are connected and everything is pretty much done. I'm giving it a one last final squeeze up top making sure that the faucet is in place and then we'll be ready to go ahead and see if it works once. I have it set up the way I do everything looks fine to me. So now it's time to turn on the water and after a little bit of air goes through we see that the water does come out. At first it comes out black because there is some residue from the factory in the faucet just run the water for a good bit and that will get all the residue out and also make sure to test your hot and cold water lines and you can double check to make sure it is the way you want. It make sure that the hot water indicator produces hot water and the cold water indicator produces cold water and that's pretty much it at this point we have successfully installed. The faucet connected the water lines and everything works the way it should and there we go. I told you it was quick and easy one thing. I would mention is that you really want to have the right faucet for your sink and I don't mean just fitting it in but also the dimensions mine it kind of curves a little bit outwards. So if you have the water on full blast you can spray it out of it. So I turned down the water pressure underneath my my sink to stop that from happening. But if you have a very small sink you might want to get a smaller faucet or one that shoots straight down other than picking the right faucet.
