What can be done to clear standing water in a sink?

1. Check and Clean the Drain: Pour boiling water down the sink drain to clear any clogs. Use a drain snake or a drain cleaner to remove any accumulated debris.

2. Use Baking Soda and Vinegar: Pour 1 cup of baking soda followed by 1 cup of vinegar down the drain. Cover the drain and let it sit for 30 minutes. Then flush the sink with boiling water.

3. Try Salt and Baking Soda: Mix equal parts of salt and baking soda. Pour the mixture down the drain and flush with hot water.

4. Use a Plunger: Create a seal over the drain with the plunger. Then, vigorously plunge up and down to create suction. This can help dislodge any clogs.

5. Check for Blockage Under the Sink: If the above methods don't work, check under the sink for any blockages. Tighten any loose connections, replace old pipes if needed, and ensure the P-trap is not blocked.

6. Call a Plumber: If none of the above methods work, you may need to call a plumber to assess and clear the clog.
