## How to Replace a Kitchen Sink Overflow
If the overflow on your kitchen sink is cracked, leaking, or otherwise damaged, it’s important to replace it as soon as possible. A damaged overflow can lead to water damage, which can be costly to repair. Replacing a kitchen sink overflow is a relatively easy task that can be completed in a few hours.
### Tools and Materials
* New kitchen sink overflow
* Adjustable wrench
* Plumber’s putty
* Utility knife
* Rags
### Step-by-Step Instructions
1. **Turn off the water supply to the sink.** This is typically done by turning off the angle stop valves under the sink. If there are no angle stop valves, you will need to turn off the main water supply to the house.
2. **Disconnect the old overflow from the sink.** Use an adjustable wrench to loosen the nut that holds the overflow in place. Once the nut is loose, you can pull the overflow out of the sink.
3. **Clean the area around the overflow hole.** Use a rag to clean away any old plumber’s putty or debris.
4. **Apply a bead of plumber’s putty around the overflow hole.** Use your finger to smooth out the putty and create a seal.
5. **Insert the new overflow into the hole.** Push the overflow into the hole until it is flush with the surface of the sink.
6. **Tighten the nut to secure the overflow.** Use an adjustable wrench to tighten the nut until it is snug. Do not overtighten the nut, as this can damage the overflow.
7. **Turn on the water supply to the sink.** Check for leaks around the overflow. If there are any leaks, tighten the nut further.
