Step 2: Use a plunger
Next, fill the sink with enough water to cover the plunger. Place the plunger over the drain and use it to create suction. Push and pull the plunger up and down for about 20-30 seconds. If the water starts to drain, continue plunging until the sink is empty.
Step 3: Try a drain snake
If the plunger didn't work, try using a drain snake. Insert the snake into the drain and push it through until you feel resistance. Twist and turn the snake to break up the blockage. Once you feel the blockage has cleared, slowly pull the snake out of the drain.
Step 4: Use a baking soda and vinegar solution
If the plunger and snake didn't work, you can try using a baking soda and vinegar solution. First, pour a cup of baking soda down the sink drain. Then, pour a cup of vinegar down the drain. Let the mixture sit for about 30 minutes, then flush the drain with hot water.
Step 5: Call a plumber
If none of these steps work, it may be time to call a plumber. A plumber will have the necessary tools and expertise to diagnose and fix the problem.
By following these steps, you can quickly and easily unblock your kitchen sink and get back to using it without any further problems.
