## [How to Cap Off Kitchen Sink Holes](https://www.hunker.com/13424517/how-to-cap-off-kitchen-sink-holes)
If you’re remodeling your kitchen or replacing your sink, you may need to cap off the old sink holes. This is a relatively simple task that can be completed in a few steps.
**Materials You’ll Need:**
* Sink hole caps
* Plumber’s putty
* Adjustable wrench
* Utility knife
* Rags
**Instructions:**
1. **Remove the old sink.** If you’re replacing your sink, you’ll need to remove the old one first. To do this, turn off the water supply to the sink and disconnect the drainpipes. Then, loosen the nuts that hold the sink in place and lift it out of the countertop.
2. **Clean the sink hole.** Once the old sink is removed, clean the sink hole thoroughly. Remove any debris or old sealant from the hole.
3. **Apply plumber’s putty to the sink hole cap.** Roll out a small amount of plumber’s putty and form it into a ball. Press the ball of putty into the center of the sink hole cap.
4. **Insert the sink hole cap into the hole.** Align the sink hole cap with the hole in the countertop and press it into place. Make sure that the putty is evenly distributed around the edge of the cap.
5. **Tighten the sink hole cap.** Use an adjustable wrench to tighten the nut that holds the sink hole cap in place. Make sure that the cap is snug but not overtightened.
6. **Clean up any excess putty.** Use a utility knife to remove any excess putty that has squeezed out from around the sink hole cap.
7. **Turn on the water supply.** Once the sink hole cap is installed, turn on the water supply to the sink and check for leaks. If there are any leaks, tighten the nut on the sink hole cap until the leak stops.
**Tips:**
* If you’re having trouble getting the sink hole cap to fit snugly, you can use a little bit of silicone caulk to seal the gap.
* If you’re not sure how to remove the old sink, consult a plumber.
* Be careful not to overtighten the nut on the sink hole cap, as this could damage the countertop.
