How to Unblock a Sink

1. Boiling Water Method

One of the simplest ways to clear a blockage is by using boiling water.

• Boil a kettle of water and carefully pour it directly down the drain.
• Wait a few minutes to see if the blockage clears.
• Repeat the process if necessary.

This method is effective for any minor grease and soap scum blockages but may not work for more stubborn clogs.

2. Baking Soda and Vinegar

This natural cleaning method can help break down debris that has built-up on the inside of your pipes.

• Pour one cup of baking soda down the drain.
• Follow with one cup of white vinegar.
• Let the mixture fizz and sit for 15-30 minutes.
• Flush the sink with hot water to wash away the loosened debris.

This method is great for breaking down grease, soap scum, and minor food blockages.

3. Use a Plunger

A plunger is a handy tool for removing any blockages from your household sinks.

• Fill the sink with a few inches of water to create a seal.
• Position the plunger over the drain and pump it up and down vigorously for 30 seconds.
• Check if the water drains properly.
• Repeat if necessary.

If the blockage is near the surface, this method should help dislodge it quickly.

4. Remove and Clean the U-Bend

If other methods don’t work, you may need to manually clean the U-bend under your sink.

• Place a bucket under the U-bend to catch water.
• Unscrew the U-bend carefully.
• Remove any debris inside the pipe.
• Rinse it thoroughly before reattaching it.
• Run water to ensure the blockage is gone.

This method is really effective for getting rid of food debris and solid obstructions but requires some DIY confidence.

5. Drain Snake or Wire Hanger

A drain snake or a straightened wire hanger can be used to dislodge stubborn blockages.

• Insert the drain snake or hanger into the plughole.
• Push it down and twist to break up the clog into tinier pieces.
• Pull out any debris and dispose of it in the garbage bin.
• Run hot water to clear any remaining residue.
