## How to Replace a Kitchen Sink Drain Gasket
A kitchen sink drain gasket is a small, rubber washer that fits around the base of the drain assembly to create a watertight seal. Over time, gaskets can become worn or damaged, which can lead to leaks. Replacing a kitchen sink drain gasket is a relatively simple plumbing repair that you can do yourself with a few basic tools.
### Materials You’ll Need
* New kitchen sink drain gasket
* Adjustable wrench
* Plumber’s putty (optional)
* Dish soap
* Rags
### Step-by-Step Instructions
**1. Turn off the water supply.** The first step is to turn off the water supply to your sink. This will prevent water from leaking out when you remove the drain assembly. To turn off the water supply, locate the shut-off valves under your sink and turn them clockwise.
**2. Remove the old gasket.** Once the water supply is turned off, you can remove the old gasket. Place a rag under the drain assembly to catch any water that may leak out. Using an adjustable wrench, loosen the nuts that hold the drain assembly in place. Once the nuts are loose, you can remove the drain assembly by lifting it up and out of the sink. The old gasket will be located around the base of the drain assembly. Remove the old gasket and discard it.
**3. Clean the drain assembly.** Once the old gasket is removed, you can clean the drain assembly. Use a clean rag and some dish soap to remove any dirt or debris from the drain assembly. Rinse the drain assembly thoroughly with water and dry it with a clean rag.
**4. Apply plumber’s putty (optional).** If your sink is made of cast iron, you may want to apply a bead of plumber’s putty around the base of the drain assembly. This will help to create a watertight seal and prevent leaks.
**5. Install the new gasket.** Take the new gasket and place it around the base of the drain assembly. Make sure that the gasket is seated properly and that it is not twisted or torn.
**6. Reinstall the drain assembly.** Once the new gasket is in place, you can reinstall the drain assembly. Align the drain assembly with the drain hole in the sink and lower it into place. Tighten the nuts that hold the drain assembly in place using an adjustable wrench.
**7. Turn on the water supply.** Once the drain assembly is reinstalled, you can turn on the water supply and check for leaks. Slowly turn on the water and watch for any leaks around the base of the drain assembly. If you see any leaks, tighten the nuts further until the leaks stop.
### Tips
* If you are having trouble removing the old gasket, you can use a flathead screwdriver to pry it loose.
* Be careful not to overtighten the nuts that hold the drain assembly in place. Overtightening the nuts can damage the drain assembly or the sink.
* If you are replacing the gasket on a kitchen sink with a garbage disposal, you will need to remove the disposal before you can access the drain assembly.
