Clean Up The Drain And Sink

How To Install Bathroom Sink Drain/Faucet, No Leaks Under Gasket, Threads [SOLVED]

Once you’ve removed the drain components, you should be able to lift the drain from the sink. You may notice residue around the drain, including plumber’s putty. Now that you’ve removed all the old hardware, clean up the drain, sink, and faucet. Be sure to remove any dirt, grime, or old sealant left behindthis will ensure that your new sink drain looks great and that you get a tight seal to prevent leaks.

Install The New Drain Assembly

Insert the drain assembly through the opening from the top side of the sink. If you have long enough arms, you can hold the drain in place while pushing the rubber gasket up the threaded section of the drain assembly from the bottom side.

If you cant hold the drain in place, no worries! Simply lay a towel in the sink to protect the finish and place a heavy object like a book or bowl full of water over the drain.

Avoid Gasket Goof Up

Make sure you install the rubber gasket with the narrowest section against the bottom of the sink. These stepped gaskets are shaped like cones to help them seal properly to the underside of the sink.

After the rubber gasket has been slid up the drain stem, follow it up by the washer and then the nut. The washer acts as a friction disk that allows you to spin the nut without affecting the surface of the gasket. This makes for a gasket that seals flat and evenly.

For most bathroom sinks, the drain stopper apparatus is a pop-up assembly that works by means of a small vertical rod attached to a pivot rod below the sink. This lift rod slides up and down through a small hole in the back of the faucet body. The pivot rod moves a linkage inside the drain tailpiece, lifting or lowering the stopper as needed.

You’ll need to install a new drain stopper whenever you install a new sink. And sometimes when you are installing a new faucet, it may come with a stopper assembly that needs to be swapped out with the old stopper. Finally, if a sink drain begins to leak, you can buy a new stopper assembly to replace the old faulty one.

Installation of a drain stopper is usually fairly straightforward and simple, but occasionally the process can become a little more complicated due to variations in the fixture or fittings.

How To Replace A Drain In The Bathroom Sink


Do you think youre due to replace drain systems in your home?

A sink is one of the essential features that your bathroom should have. It plays a vital role in helping you wash your face and brushing your teeth. Once your sink drain gets old, it can get rusty and give out a bad smell.

You should clean your drain at least once a year. If youve avoided cleaning your drain, you could encounter troubles with clogs. So, heres a guide to help you know which drain is best for your sink and how to replace drains.

Remove The Old Drain Assembly

Loosen and remove the P-trap from the branch drain and sink drain tailpiece, using channel-type pliers. With some traps, you may be able to loosen and remove the trap by hand, without a wrench. It’s possible there will be some water in the trap, so position a bucket under the trap to catch this water.

Next, extract the old pop-up linkage assembly, if there is one.

Now, use channel-type pliers to remove the mounting nut from the tailpiece on the old drain assembly. Lift the entire drain assembly clear of the sink. This may require some wiggling of the tailpiece to break the seal on the drain flange.

With the drain assembly removed, clean the sink thoroughly of debris and old plumber’s putty.

  • Make sure you’ve removed any old putty from the sink with wet rags and a plastic putty knife first.

  • 3Stack any included gaskets on top of the locknut or bell housing. Without these one or more gaskets that came with the kit, you’ll have a metal-to-metal compression connection under the sink that won’t be watertight.

Beneath the sink, you’ll find a vertical metal bar with a series of holes in it connected to an angled rod that enters the sink’s drainpipe . To disconnect them, pinch the V-shaped spring clamp that holds them together. Keep the clamp and all other pieces you disconnect for future reference.XResearch source
  • 2Unscrew the pivot nut and pull it out with the pivot rod. The pivot nut is threaded onto a short stub on the drainpipe, and is the entry point for the pivot rod into the drain. Turn the nut counterclockwise by hand or use a wrench if necessary to unthread it. Pull it straight off along with the inserted pivot rod. You should now see the pivot ball nestled inside the nut, along with the stub of the pivot rod that connects to the stopper inside the pipe.XResearch sourceAdvertisement
  • 3Undo the screw that connects the extension bar and lift rod. The vertical extension bar is connected by a clevis with the lift rod that extends to the topside of the sink. Undo the screw to unfasten the lift rod, then pull the lift rod out from above the sink.XResearch source

    S Youll Need When Installing A New Sink Drain:

  • First, youll need a P trap kit
  • Some kits come with a P trap adapter, otherwise youll need to purchase one separately
  • Lastly, youll need a pop-up drain assembly for your sink. It will either come with your sink or can be purchased separately.
  • If you have a brand new vanity like me, the first step is to make a hole in the vanity top. To mark the hole placement I lined up my laser level with the faucet rough-in and used a speed square to make sure I was square with the vanity.

    Ideally you want the center of the faucet aligned with the drain hole as shown in the picture below, so to figure out the distance I referred to my faucets spec sheet and found the distance from the center of the spout to the wall.

    I could then mark the location for the drain hole measuring from the wall. To make the hole I used a hole saw slightly larger than the diameter of my sinks drain hole, and slowly drilled my may all the way through the vanity top.
