## How to Repair a Kitchen Sink Drain Seal
A leaky kitchen sink drain can be a real nuisance. Not only is it unsightly, but it can also lead to water damage and mold growth. If you’re not sure how to fix a leaky sink drain, don’t worry – it’s actually a pretty easy repair that you can do yourself.
### What You’ll Need
* Adjustable wrench
* Plumber’s putty
* Utility knife
* Rags
### Step-by-Step Instructions
1. **Turn off the water supply.** The first step is to turn off the water supply to your kitchen sink. This will prevent any water from leaking out while you’re working on the repair.
2. **Remove the drain stopper.** Once the water supply is turned off, you can remove the drain stopper. This is usually done by simply unscrewing it.
3. **Clean the drain opening.** Once the drain stopper is removed, you can clean the drain opening. Use a rag to wipe away any debris or gunk that has built up.
4. **Apply plumber’s putty.** The next step is to apply plumber’s putty to the drain opening. Plumber’s putty is a type of sealant that will help to create a watertight seal between the drain and the sink. To apply plumber’s putty, simply roll it into a rope and then place it around the drain opening.
5. **Reinstall the drain stopper.** Once the plumber’s putty is in place, you can reinstall the drain stopper. Be sure to tighten it securely.
6. **Turn on the water supply.** Once the drain stopper is reinstalled, you can turn on the water supply and check for leaks. If there are no leaks, then the repair is complete.
### Tips
* If you’re not sure how to turn off the water supply to your kitchen sink, consult your owner’s manual or call a plumber.
* If you don’t have any plumber’s putty on hand, you can use petroleum jelly or silicone caulk instead.
* If the leak is coming from the base of the drain, you may need to replace the entire drain assembly.
### Troubleshooting
* **The leak is still there after I’ve followed the steps above.** If the leak is still there after you’ve followed the steps above, it’s possible that the drain is cracked or damaged. In this case, you will need to replace the drain.
* **The water is draining slowly.** If the water is draining slowly, it’s possible that there is a clog in the drain. Try using a drain cleaner to clear the clog.
### Conclusion
Repairing a kitchen sink drain seal is a relatively easy repair that you can do yourself. By following the steps above, you can quickly and easily fix the leak and get your sink back in working order.
