Does your sink not drain? Does it not let you fill the basin with water? If so, your sink's pop-up assembly in the drain may be broken.
What has happened in the sink, is the pop-up mechanism (or assembly) has broken. When a pop-up assembly is working correctly, it is fairly simple, using leverage to open and close the drain. When you pull up on the lift rod on the back of your sink, the stopper is closed, and when you push the rod down, the stopper opens.
The lift rod that you are pulling up is attached to what is called the pivot rod, which is connected to your drain stopper. When the lift rod is pulled up, it pulls up the pivot rod, which pulls down the drain stopper.
There are a few reasons why this part of your sink might not be working. The part of the pivot rod that connects to the drain stopper may have rusted or broken off, or the drain stopper itself might be broken so that the pivot rod can’t actually pull the stopper down. There might not be enough leverage from your lift rod on your pivot rod, even. If your sink isn’t draining well, and you can open and close your pop-up mechanism, it might be because there is something that you need to clean out of the drain that has caught on the mechanism.
Before you call a plumber, you can fix this yourself, for a lot less money. Whatever the problem is with your pop-up mechanism, you can easily find replacement parts at a hardware store. There are universal kits you can purchase for anywhere between $4.00 and $14.00.
After purchasing a repair kit, the actual repair process is extremely easy. If you don't know what part is what is in a pop-up assembly, we published a post on how your pop-up assembly works. Familiarize yourself with the parts of the assembly so you know how to complete this DIY project.
Before you start repairing or cleaning your pop-up drain, make sure to turn the water off on your sink, ensure the back of the sink is accessible and put a bucket underneath the drain, just in case.
Leave the clevis strap where it is hanging and twist off the gasket that is holding the pivot rod in the drain.
Clean off your drain stopper in a different sink if you are just doing maintenance. At this time, clean out your drain, too. If you are replacing the stopper, unscrew the cap on the top, and screw on the new drain bottom.
Make sure that you put the new or cleaned drain stopper with the hole facing out toward you. This way, the pivot rod can go through the hole at the bottom of the drain stopper and move it up and down.
Make sure to attach the clevis strap and the pivot rod on the same hole as before, or increase the leverage by changing the holes the pivot rod goes through. pinch the spring clip around the clevis strap to ensure the clevis strap will not fall off the pivot rod.Congratulations, you've successfully changed out your pivot rod and sink pop-up assembly. If you have a home warranty with Landmark Home Warranty, you may have noticed that pop-up assemblies are not included in the list of things that are covered with a home warranty.
