• 00:00 - My name is Aaron Massey from mrfixitdiy.com and welcome back to another episode of Home School. For today's project, I'm gonna show you how to install a bathroom faucet. Plumbing is one of those projects many homeowners hire out for but today. I'm gonna show you how to tackle installing a bathroom faucet without making an expensive call to a plumber. There are many types of bathroom faucets out there from single hole and single handle faucets to wall-mounted and bridge faucets. For this project, I'll be installing a wide spread faucet on a drop-in sink. The sink you choose often dictates which type of faucets you can use, so make sure to keep that in mind when you're looking at sinks for your remodel project.

• 00:39 This particular faucet is a moen oxby widespread faucet which means the sink has three holes and the outer holes are more than four inches apart. The install principles will be the same with most widespread faucets. I rate these projects by how many f-bombs you're likely to drop. While tackling the project, this one isn't too difficult. But as I mentioned, some people have a reluctance towards plumbing and it can take a little bit of patience and a few basic tools to knock it out. Once you have the proper style faucet for your sink, step one is to remove the old faucet if you're replacing it with a new one. This is a newly remodeled bathroom, so I don't have an old one to remove in this case, but make sure that you remove any old caulk or sealants as well as any old gaskets that may be present so you have a nice clean sink to work with. Next, install the faucet spout and stem assembly by applying some bread tape to the stem and threading it onto the spout assembly.

• 01:31 Apply a small bead of plumbers putty around the base of the spout assembly and insert the spout assembly into the center hole of the sink. Mount it in place with the included hardware kit and tighten it in place using the included valve socket wrench. Next, thread the mounting nut and mounting washer to the valve assemblies and apply a small bead of plumbers putty around the base of the upper washer. Insert the valve assemblies from the underside of the sink and secure them in place with a washer and retaining clip. Make sure the blue-colored cold valve goes in the right hole and the red-colored hot valve goes in the left hole. Tighten the mounting nuts from the underside to tighten the valve in place. From there, install the faucet handles by threading them onto the valve assemblies and tightening them down by hand.

• 02:20 Slide the lift rod into place in the whole of the backside of the faucet and then next you can start installing the drain assembly. Unscrew the top of the drain assembly called a waste seat and apply a bead of plumbers putty around the underside before inserting it into the drain hole in the bottom of the sink. Apply some thread tape onto the drain assembly and then thread it into the waste seat from the underside and tighten it down. Make sure the threaded hole that protrudes out on the drain. Pipe is facing the back and tighten the drain nut to secure it and the gasket in place making it watertight. You should have some squeeze out of plumber's putty in the sink itself which you can simply wipe away. From there you can move on to attaching the lift rod in the sink plug. Add some thread tape to the hole on the back side of the drain assembly, slide the locking nut over the ball rod and insert it into the hole.

• 03:12 Tighten the nut as much as possible by hand. Attach the lift strap with the adjustable holes to the lift. Rod and the ball rod and secure it in place with a locking clamp and tighten the screw on the lift rod. You can adjust how the lift rod operates by sliding it up and down on the various holes on the strapping. Make sure it works for you by testing out the lift rod and making sure that the plug seats into the sink properly and then you can attach the included water lines that come with your faucet. This is one piece hose, so attach the diverter hose by snapping the ends over the valve bodies and the faucet stem assembly.

• 03:45 You know they're seated properly when you hear a nice click. Now, if you're working in a remodeled bathroom like this one and you don't have an existing p-trap to tie into already installed, next I'll show you how to connect it. Assemble the p-trap assembly by sliding the washer and slip nut over the end of the joint elbow and wrap the end in thread tape. Connect the trap and elbow by tightening the nut by hand. Add the down pipe to the drain assembly by sliding the slip nut and washer over the drain assembly and slide the trap assembly into the drain pipe in the wall.

• 04:18 Once you have everything aligned, tighten the slip nuts at each joint by hand before snugging them up with a pair of channellock pliers. Install your water lines from the valves and connect them to the new valves on the faucet. And lastly, turn the water on at the valves, check to see that the faucet is working properly and check the drain assembly for any leaks. If you have a small leak, try tightening the nuts further with your pliers.
