## How to Remove a Kitchen Sink Drain Collar
A kitchen sink drain collar is a rubber or metal ring that fits around the base of the drain assembly. It helps to keep water from leaking out around the drain and also helps to prevent clogs. Over time, the drain collar can become worn or damaged and need to be replaced.
### Materials You’ll Need
* Adjustable wrench
* Plumber’s putty
* New drain collar
### Step-by-Step Instructions
1. **Turn off the water supply to the sink.** This is usually done by turning the valves under the sink.
2. **Use an adjustable wrench to loosen the locknut that holds the drain assembly in place.** The locknut is usually located directly below the drain collar.
3. **Once the locknut is loose, you can remove the drain assembly by pulling it straight up.** Be careful not to drop any of the parts.
4. **Remove the old drain collar from the drain assembly.** It may be necessary to use a knife or a screwdriver to pry the collar off.
5. **Apply a small amount of plumber’s putty to the base of the new drain collar.** This will help to create a watertight seal.
6. **Place the new drain collar on the drain assembly.** Make sure that the collar is seated properly.
7. **Reinstall the drain assembly into the sink.** Make sure that the locknut is tightened securely.
8. **Turn on the water supply to the sink and check for leaks.** If there are any leaks, you may need to tighten the locknut further.
### Tips
* If you are replacing a metal drain collar, it is important to use a new washer when you reinstall the drain assembly.
* If you are having trouble removing the old drain collar, you can try using a penetrating oil to loosen it.
* If you are not comfortable with doing this repair yourself, you can call a plumber to do it for you.
### Additional Information
In addition to the steps listed above, there are a few other things you can do to make sure that your kitchen sink drain collar is installed properly.
* Make sure that the sink drain is clean before you install the new collar. Any dirt or debris can prevent the collar from creating a watertight seal.
* Use a flashlight to inspect the drain assembly before you reinstall it. Make sure that there are no cracks or other damage.
* If you are replacing a metal drain collar, use a new locknut when you reinstall the drain assembly. The old locknut may be worn or damaged and may not be able to hold the drain assembly in place properly.
