Installing the new Bathroom Faucet Drain Assembly | Part 2

Before we install the new drain assembly for our bathroom faucet, we want to apply a little silicone sealant to the area around the drain at the bottom of the sink.  This will greatly improve the tight seal we need around the drain hole so we don't get a leak.   Using the silicone sealant now in the project means we have a much smaller chance of finding leaks later in the project and will save a great deal of time loosening and tightening trying to stop the leaks later.

Now lets grab the new drain assembly and go to town.  Most modern bathroom faucet kits come with all the components screwed together on the right order so you can see what order the nuts and washers will go in.  Unscrew the parts of the drain assembly and pay close attention to their order.  Put the top part(drain plug) in over the top of the sink and then screw the flange pipe coming in from under the sink.  Make sure you have the large nut, then metal washer(if you have one), then the rubber washer on the flange pipe in that order before connecting it to the drain plug. You also want to make sure the J-Unit plastic nut first then washer are around the flange pipe also before putting the flange pipe down into the J-Unit.  It is a good idea to put some silicone sealant around the threads of both large nuts here. This will help ensure there are no leaks.

If you put everything on the flange pipe here correctly, all you should have to do know is tighten everything up and test the flowing water through the drain pipe.

If you have any questions about this process or are stuck, please feel free to post a comment and ask a question.  We are happy to help and take a look at our bathroom faucets and kitchen faucets to add to your home.

Next, we will start with the fun stuff.  Installing the actual bathroom faucet.
