Pop-Up Drain Stopper

Do you know how to install a pop-up drain stopper? A bathroom sink pop-up stopper is a very useful feature. The process of installing a pop-up drain stopper is easy as well as complicated due to variations in the fixture or fittings. Stay with Eama and follow the instruction we have prepared for installing a pop-up drain.


What do you need for installing a pop-up drain stopper?

  • Channel-type pliers

  • Pop-up drain assembly

  • Pipe joint compound

  • Plumber's putty

How to install a pop-up drain stopper?

Remove the Old Drain Assembly The first step would be, Losing and removing the P-trap from the branch drain and sink drain tailpiece by using channel-type pliers. Next, if there is an old pop-up assembly, remove it completely. By the channel-type pliers or a basin wrench remove the mounting nut from the tailpiece on the old assembly. Then it is time to clean the sink from debris and old plumber's putty.


Prepare the New Pop-Up Drain Stopper Disassemble the pieces of the new pop-up assembly, and unscrew and remove the mounting nut from the drain tailpiece. Install the plastic washer then the rubber washer and push them all the way down on top of the mounting nut, as shown here.

Apply Pipe Joint Compound

Apply a thin layer of pipe joint compound to the top side of the rubber washer that will fit against the sink. Using joint compound on the rubber will ensure that it seals against the bottom of the sink drain opening. While pipe joint compound is not strictly necessary, without it you might have trouble getting the rubber to seal.


Apply Plumber's Putty

Apply a generous bead of plumber's putty to the underside of the flange on the sink drain ring. The putty will help the upper part of the drain assembly seal against the sink drain opening.

If you do not have a plumber's putty or cannot use it on your type of sink, then you can use silicone caulk. Some pop-up assemblies come with a foam or rubber gasket to use in place of the plumber's putty or caulk.

Connect the Drain Parts

Push the pop-up drain tailpiece assembly up through the drain opening from under the sink as high as you can. While holding the drain piece in place, fit the drain ring into the opening from the top of the sink, and thread the ring onto the drain tailpiece as far as you can by hand. Make sure the pieces are threaded correctly and are not cross-threaded. For now, it only needs to be hand-tightened enough to hold it in place.


Tighten the Drain Assembly

From under the sink, hold the drain tailpiece with one hand and tighten the mounting nut upwards toward the bottom of the sink. Make sure the opening in the tailpiece where the pop-up pivot lever will fit is pointing straight back toward the wall.

Tighten the mounting nut with channel-type pliers while continuing to hold the tailpiece in place. Do not over-tighten this nut, but make sure it is secure enough so that the drain assembly does not spin in the drain opening.

Put the Drain Stopper Into Place Push the pop-up stopper down into the drain opening inside the sink, making sure the hole in the linkage is facing toward the back of the sink. Insert the pivot rod into the opening in the side of the tailpiece from under the sink. Usually, there is a plastic washer on each side of the plastic ball. You should be able to feel the tip of the pivot rod slide through the opening in the stopper linkage inside the drain assembly. Screw the pivot rod nut onto the threaded fitting on the side of the tailpiece, so the ball is secured to the tailpiece. Push the pivot rod up and down to make sure the stopper goes up and down freely in the drain. If the pop-up is working properly, you can tighten the nut hand-tight. If the pop-up is not working, reposition the stopper and pivot rod so the pieces connect properly.

Install the Pop-Up Lever Feed the vertical pop-up lever down through the hole behind the spout of the faucet. Before connecting the horizontal pivot rod to the vertical lever, make sure your stopper is in the fully up (open) position. From below the sink, attach the connecting strap to the end of the vertical pop-up lever. Tighten the screw on the connecting strap to secure it to the pivot rod.


Connect the Pop-Up Lever and Pivot Rod

Connect the vertical strap to the horizontal pivot rod by threading the spring clip onto the rod; one end of the clip attaches on each side of the strap. Check to make sure that the pop-up stopper opens and closes fully inside the drain opening. If it doesn’t, you can make some adjustments to the rod connections by pinching and moving the spring clip.

Finish the job by reconnecting the P-trap to the drain pipe and drain tailpiece. Check for leaks by closing the stopper, filling up the sink, then opening the stopper and letting the water drain out while you look for leaks from below.
