Remove Old Drain
Before you can install your new pop-up drain, you need to remove the old drain from your sink. This can be a challenging task, especially if the old drain has been in place for a long time. Here’s a step-by-step guide on how to remove the old drain:
-
Turn off the water supply: Before you begin the removal process, ensure that the water supply to your sink is turned off. You can do this by shutting off the valves under your sink.
-
Remove the sink stopper: The sink stopper is usually attached to the drain rod, which is located behind the faucet. You can remove it by unscrewing the nut that holds it in place.
-
Loosen the locknut: Locate the locknut that holds the drain assembly in place and use pliers or a wrench to loosen it.
-
Remove the drain assembly: Once the locknut is loosened, you can remove the drain assembly from the sink. Gently wiggle it back and forth until it comes loose.
-
Clean the area: Before installing the new drain, ensure that the area around the drain is clean and free of debris. You can use a putty knife to remove any excess putty or caulk.
Removing the old drain can be a challenging task, but with these steps, you can complete the process with ease. In the next section, we’ll provide you with a step-by-step guide on how to install the pop-up drain.

Remove Old Drain (Continued)
Removing the old drain can be a challenging task, and there are common challenges you may experience during the process. Here are some challenges you may encounter and how to overcome them:
Rusty or corroded parts
If your old drain has been in place for a long time, the parts may be rusty or corroded, making them difficult to remove. To overcome this challenge, apply penetrating oil to the parts and let it sit for a few hours before attempting to loosen them.
Stubborn locknut
The locknut that holds the drain assembly in place can be challenging to remove, especially if it’s been tightened too much. To loosen a stubborn locknut, use a pair of pliers or a wrench and apply pressure in a counterclockwise direction. If this doesn’t work, you can try using a locknut wrench or a basin wrench.
Damage to the sink
Removing the old drain can sometimes cause damage to the sink. To prevent this, be gentle when removing the drain assembly and use a putty knife to remove any excess putty or caulk.
With these tips, you can overcome common challenges and remove the old drain with ease.
Install Pop Up Drain
Now that you’ve successfully removed the old drain, it’s time to install the new pop-up drain. Here’s a step-by-step guide on how to install the pop-up drain:
-
Install the sink drain flange: Apply plumber’s putty to the underside of the sink drain flange and insert it into the sink’s drain hole. Ensure that it’s centered and pressed firmly into place.
-
Install the rubber gasket: Place the rubber gasket over the sink drain flange and ensure that it’s seated properly.
-
Install the tailpiece: Screw the tailpiece onto the sink drain flange and tighten it using pliers or an adjustable wrench.
-
Install the pop-up drain assembly: Insert the pop-up drain assembly into the tailpiece and tighten it using pliers or a wrench.
-
Connect the drain pipe: Connect the drain pipe to the tailpiece and ensure that it’s tightened properly.
-
Test the drain: Turn on the water supply and test the drain to ensure that it’s working properly. If there are any leaks, tighten the connections and test again.
While installing a pop-up drain is a simple process, there are common mistakes you should avoid:
Not using plumber’s putty or silicone caulk
It’s crucial to use plumber’s putty or silicone caulk when installing the sink drain flange to prevent leaks. Skipping this step can result in water leaking into the cabinet below the sink, causing damage.
Over-tightening connections
Over-tightening connections can cause damage to the sink and the drain assembly. Ensure that you tighten the connections properly to prevent leaks, but avoid over-tightening them.
By following these steps and avoiding common mistakes, you can install a pop-up drain in your bathroom sink with ease.
Test Drain
After installing your pop-up drain, it’s essential to test it to ensure that it’s working correctly. Here’s a step-by-step guide on how to test your pop-up drain:
-
Add water to the sink: Turn on the water supply and let the water run for a few minutes. This will allow the sink to fill up with water.
-
Test the drain stopper: Push down on the drain stopper to make sure it opens and closes correctly. Ensure that the stopper is sealing correctly and preventing water from flowing down the drain.
-
Check for leaks: Look under the sink for any signs of leakage. If you notice any leaks, turn off the water supply and tighten any loose connections.
-
Test the pop-up drain: Once you’ve tested the drain stopper and checked for leaks, test the pop-up drain by pulling up on the lift rod. The pop-up drain should rise, allowing water to flow down the drain. Push down on the lift rod to ensure that the pop-up drain closes correctly.
If you notice any issues during the testing process, don’t panic. Here are some troubleshooting tips for common pop-up drain issues:
-
If the drain stopper isn’t sealing properly, adjust the stopper’s position or clean any debris that may be preventing it from sealing correctly.
-
If the pop-up drain isn’t rising, make sure that the lift rod is properly connected to the drain assembly. You can adjust the lift rod’s position by tightening or loosening the set screw.
-
If you notice any leaks, tighten any loose connections or replace any damaged gaskets.
With these troubleshooting tips, you can easily fix any issues that arise with your pop-up drain.
