Your sink is likely not draining water due to a blockage in the drainpipe. This blockage can be caused by various factors, but a common culprit is a build-up of fats, food particles, hair, and other debris.
Potential Causes and Solutions
Here's a breakdown of potential causes and how to address them, based on general knowledge and the reference provided:
1. Clogged Drainpipe
This is the most common reason for a slow or non-draining sink. The clog restricts water flow, leading to backups.
- Solution:
- Boiling Water: A quick and easy first step, particularly for clogs caused by fats, is to carefully pour boiling water slowly down the drain. Let it sit for 1-2 minutes to allow the boiling water to melt the fats and then run the hot top to clear the pipes. Important safety note: Be cautious when pouring boiling water, especially in sinks made of materials that could be damaged by high heat.
- Plunger: Use a sink plunger to create suction and dislodge the blockage. Make sure there's enough water in the sink to cover the cup of the plunger.
- Baking Soda and Vinegar: Pour 1 cup of baking soda followed by 1 cup of vinegar down the drain. Let it fizz for 30 minutes, then flush with hot water.
- Drain Snake/Auger: Use a drain snake (also called an auger) to physically break up or remove the clog.
2. Blocked P-Trap
The P-trap is the curved pipe under the sink. It's designed to trap debris and prevent sewer gases from entering your home. However, it can also become clogged with larger items.
- Solution: Place a bucket under the P-trap, loosen the slip nuts connecting the P-trap to the drain pipes, and carefully remove the P-trap. Clean out any debris inside. Reassemble the P-trap, ensuring the connections are tight.
3. Venting Issues
If the drain isn't properly vented, air can't enter the drainpipe to replace the water flowing out, creating a vacuum and slowing drainage.
- Solution: This issue is more complex and often requires a professional plumber. You can try using a plunger to see if you can force air through the vent.
4. Partially Blocked Sewer Line
In rare cases, a blockage in the main sewer line can affect all drains in your home.
- Solution: This requires a professional plumber with specialized equipment to clear the sewer line.
