Your sink likely isn't draining because of a blockage preventing water from flowing freely through the drainpipe.
Common Causes of a Clogged Sink Drain
A variety of factors can contribute to a clogged sink. Here's a breakdown:
-
Buildup of Debris: As stated in the provided reference, bathroom sinks are prone to clogs due to a buildup of:
- Hair
- Soap scum
- Toothpaste residue
- Other small particles
-
Grease: Grease solidifies as it cools, causing significant blockages, primarily in kitchen sinks.
-
Food Scraps: Food particles can accumulate and cause clogs over time.
-
Small Objects: Items accidentally dropped down the drain, like jewelry or small toys, will cause immediate blockages.
-
Pipe Issues: In some cases, problems within the drainpipe itself (e.g., collapsed or misaligned pipes) can restrict flow.
How to Troubleshoot a Slow-Draining Sink
-
Check the Stopper: Ensure the stopper is clean and functioning correctly. Hair and debris often get caught around the stopper mechanism.
-
Plunge the Drain: Using a standard plunger can often dislodge simple clogs.
-
Check the P-Trap: The P-trap is the curved section of pipe under the sink. It's designed to trap debris. Disconnect it (with a bucket underneath to catch water) and clean it out.
-
Use a Drain Snake: A drain snake (or auger) can reach further into the drainpipe to break up or remove clogs.
-
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.
-
Call a Plumber: If you've tried these steps and the sink still won't drain, it's time to call a professional plumber.
