There are many ways to unclog the kitchen sink. Fill the sink with water, then press down on the drain with a rubber plunger. You can also pour baking soda over the drain hose, followed by vinegar. Wait 5 minutes, then pour hot water down the drain hose. Finally, you can use the drain cable. You will need to remove the bent pipe underneath the sink (also called a siphon) and thread the drain cable into the recessed drain.

Steps

Method 1 of 3: Use a rubber plunger

1. 

   The sink partially filled with hot water. Turn on the hot water and run it into the sink until it is about 1/4 to half full.

2. 

   
   
   Place the plunger on the drain hole. If it's a two-compartment sink, you will need to insert the rag into the other outlet to make sure the pressure from the plunger concentrates on the clog.

3. 

   Accelerate the plunger up and down. Lift the plunger out of the drain to see if water has started flowing.

4. 

   
   
   Continue using the plunger until it clears. It may take a while for the block to clear. If that doesn't work, try another method. advertisement

Method 2 of 3: Use vinegar and baking soda

1. 

   Wear gloves. Use a bowl or cup to scoop water out of the sink. Fill the bucket with water.

2. 

   
   
   Pour 1 cup of baking soda down the drain. Use a powder scraper to place baking soda over the drain hole if needed.

3. 

   Pour a cup of vinegar into the drain. Put the water stopper in the sink to let the vinegar run down the clog.

4. 

   Wait 5 minutes for the solution to take effect on the clog. Turn on the warm water running down the sink to see if the clog is gone.

5. 

   Pour 4 cups of boiling water down the drain if the warm water doesn't help. If the sink remains clogged, repeat the baking soda and vinegar method again. advertisement

Method 3 of 3: Use drain cables

1. 

   Open the drawer under the sink. Place a bucket underneath the drain to catch the dripping water.

2. 

   Remove the siphon tube. A siphon is a curved tube underneath the horizontal and vertical pipes.
   • Try to screw the PVC pipes by hand.
   • If the tubes cannot be screwed up by hand, you can use the tube wrench to loosen the joints.

3. 

   Slope the water in the siphon into the bucket. Check the siphon for clogs and clean if necessary.
   • If the block is in a siphon, re-attach it after cleaning. Turn on the hot water to see if the sink can drain.
   • If the sink remains clogged, proceed to the next step using the drain cable.

4. 

   Remove the horizontal pipe connecting the siphon pipe and the recessed drain pipe. Thread the end of the cable into the recessed drain until it reaches the clog.

5. 

   Pull out a section of cable about 45 cm long from the drain hose in the wall. Tighten the locking screw.

6. 

   Rotate the crank clockwise. Rotate while pushing forward to bring the cable deeper into the tube.
   • If the cable gets caught in an obstruction, turn it counterclockwise and pull out the cable.
   • If there is an obstacle again, continue to pull out the cable and turn clockwise until the clog is clear.

7. 

   Disconnect the cables from the recessed drain. Reinsert the horizontal pipe and the siphon pipe. Do not screw the plastic parts too tightly to avoid cracking.

8. 

   Turn on the hot water tap to check the sink has drained. If the water drains slowly, partially fill the sink with the tap and use the rubber plunger to push the remaining clog open. advertisement

Advice

• If the sink has a garbage mill, fill the sink with water. If the sink has 2 compartments, you need to put the water stopper in the compartment that does not have the sewing machine. Turn on the dustbin and remove the stopper. In many cases, the garbage mill will apply enough pressure to push the clog open. You can also buy an inexpensive tool to unblock the trash mill called Zip it.

Warning

• Avoid pouring detergent down the drain. These chemicals are toxic and can damage pipes.
• Wear gloves when handling pipes with any chemicals.
