Replacing a bathroom sink drain gasket may seem like a daunting task, but with the right tools and knowledge, it can be a simple and cost-effective DIY project. A damaged or worn-out gasket can cause leaks and water damage, so it's important to replace it as soon as possible. Follow these easy steps to successfully replace your bathroom sink drain gasket.How to Replace a Bathroom Sink Drain Gasket
Before you begin, make sure you have all the necessary tools and materials. You will need a new sink drain gasket, a pair of pliers, a wrench, a putty knife, and plumber's putty. It's also a good idea to have a bucket or towel handy to catch any water that may spill out during the process.Step 1: Gather Your Tools and Materials
The first step in any plumbing project is to turn off the water supply. Locate the shut-off valves under the sink and turn them clockwise to shut off the water flow. If you can't find the shut-off valves, you can turn off the main water supply to your house.Step 2: Turn Off the Water Supply
Next, you will need to remove the drain stopper to access the drain gasket. Depending on the type of stopper you have, you may need to unscrew it or simply pull it out. If it's connected to a lever, you may need to loosen the nut holding it in place with pliers.Step 3: Remove the Drain Stopper
Using pliers, loosen the nut that secures the drain flange to the bottom of the sink. Once it's loose, you should be able to remove the flange by pulling it out from the top of the sink.Step 4: Loosen the Drain Flange
With the flange removed, you can now remove the old gasket. Use a putty knife to scrape off any remaining residue. Then, clean the area thoroughly with a mild cleaner and a scrub brush. Make sure the area is completely dry before proceeding.Step 5: Remove the Old Gasket and Clean the Area
Take a small amount of plumber's putty and roll it into a thin rope. Place the rope around the bottom of the flange where it will make contact with the sink. This will create a watertight seal for the new gasket.Step 6: Apply Plumber's Putty
Place the new gasket on top of the putty, making sure it is centered over the drain opening. Then, carefully insert the flange back into the drain opening and tighten the nut underneath with pliers.Step 7: Install the New Gasket
Reattach the drain stopper by following the steps you took to remove it. Make sure it is secure and working properly before moving on to the next step.Step 8: Reassemble the Drain Stopper
Once you've completed the installation, turn the water supply back on and check for any leaks. If everything looks good, you're all set!Step 9: Turn the Water Supply Back On
