5 . Step-by-Step Methods to Unclog a Kitchen Sink

🔹 Method 1: Boiling Water

Sometimes , the simplest method is the most effective .

Steps:

1. Boil a full kettle or large pot of water .
2. Slowly pour the boiling water down the drain in two stages .
3. Wait a few minutes between each pour .

Best for: Grease or soap build-up .

🔹 Method 2: Baking Soda and Vinegar

A classic and chemical-free solution .

Steps:

1. Pour 1/2 cup of baking soda down the drain .
2. Follow with 1 cup of white vinegar .
3. Let the mixture fizz for 10–15 minutes .
4. Flush with boiling water .

Tip: This is an eco-friendly solution ideal for light clogs .

🔹 Method 3: Use a Plunger

A plunger creates suction to dislodge debris .

Steps:

1. Fill the sink with enough water to cover the plunger head .
2. Place the plunger over the drain and press down firmly .
3. Pump up and down for 20–30 seconds .
4. Remove the plunger and see if the water drains .

Pro Tip: If you have a double sink , block the other drain with a wet cloth .

🔹 Method 4: Manual Removal (P-trap Cleaning)

Great for when the clog is just below the sink .

Steps:

1. Place a bucket under the P-trap (U-shaped pipe) .
2. Use a wrench to loosen the slip nuts .
3. Remove the trap and clean out the debris .
4. Rinse it thoroughly and reassemble .

Caution: Be prepared for dirty water and gunk!

🔹 Method 5: Plumbing Snake or Wire Hanger

This helps you reach clogs further down the drain .

Steps:

1. Insert the snake or straightened hanger into the drain .
2. Rotate and push it to break up the blockage .
3. Pull it out slowly and dispose of any debris .
4. Run hot water to clear any remaining bits .

Alternative: Buy a hand-crank drain auger for better results .

🔹 Method 6: Wet & Dry Vacuum

Powerful and effective for removing clogs .

Steps:

1. Set the vacuum to liquid mode .
2. Create a tight seal around the drain with a plunger or rag .
3. Turn on the vacuum to suck out the clog .

Warning: Do not try this with a regular household vacuum .

6 . When to Call a Professional

If none of these methods work , the blockage might be deeper in the plumbing system or part of a larger issue such as pipe collapse or tree root infiltration .
