A clogged kitchen sink can be a nightmare in the kitchen. Luckily, there are a lot of easy ways to unclog your drain!
Steps
Using a Plunger
-
1Fill the sink partially full of hot water. Fill the sink until it is about 1/4 to 1/2 of the way full.
-
2Position the plunger over the drain. If you have a double sink, then stuff a washcloth into the unclogged drain to ensure that the plunger's pressure is focused on the clog.Advertisement
-
3Work the plunger up and down quickly. Pull the plunger off of the drain opening and see if the water starts to drain.
-
4Continue using the plunger until the clog is dislodged. It may take a little while to dislodge the clog. If this does not work, then try a different method.[1]
Using Vinegar and Baking Soda
-
1Put on a pair of rubber gloves. Use a bowl or a cup to bail standing water out of the sink. Pour the water into a bucket.
-
2Push 1 cup of baking soda down the sink drain. Use a spatula to force the baking soda into the opening, if necessary.[2]
-
3Pour 1 cup of vinegar into the drain opening. Put the stopper into the sink so that the vinegar is forced toward the clog.[3]
-
4Wait 5 minutes to allow the solution to work on the clog. Run warm water into the sink to see if the clog disappears.[4]
-
5Pour 4 cups of boiling water down the drain if the warm water fails to work. If the sink is still clogged, then apply the baking soda and vinegar solution again.[5]
Using a Cable Auger
-
1Open the cabinet beneath your sink. Place a bucket underneath the pipes to catch any water that may drain out.
-
2Detach the trap.[6] The trap is the curved pipe that dips below the horizontal and vertical pipes.
- Try to unscrew PVC pipes by hand.
- If you can't unscrew the pipes by hand, then use a pipe wrench or channel locks to loosen the connections.
-
3Empty water from the trap into the bucket. Check the trap for clogs and clean the trap if needed.
- If you find the clog in the trap, reattach the trap. Turn on the hot water and see if the sink drains.
- If the sink is still clogged, then follow the next steps to use the cable auger.
-
4Remove the horizontal pipe that connects the trap to the stub pipe in the wall. Push the end of the cable auger into the stub pipe until the auger meets resistance.[7]
-
5Pull out about 18" (46 cm) of cable from the stub pipe. Tighten the lock screw.
-
6Crank the handle in a clockwise direction. Push forward as you do this to guide the auger deeper into the pipe.[8]
- If the cable catches on something, then turn the handle counterclockwise and pull the auger back.
- If the auger meets resistance again, continue pulling the cable out and cranking the handle clockwise until the cable catches on the clog.
-
7Retract the cable from the stub pipe. Reattach the horizontal pipe and the trap.[9] Do not tighten the plastic parts too much or they may crack.
-
8Turn on the hot water to see if the sink drains. If the water runs slowly, then fill up the sink part of the way and use a plunger to dislodge the remains of the clog.[10]

About This Article
To unclog your kitchen sink, try using boiling water. Just bring a pot of water to a boil, then carefully pour it down the drain of your kitchen sink. The heat from the water should help break up the clog. If that doesn’t work, try using baking soda and white vinegar. First, pour 1 cup (180 g) of baking soda down the drain. Then, pour in 1 cup (235 mL) of white vinegar. Let the baking soda and white vinegar fizz for 15 minutes, then run hot water to flush out the clog. You can also use a flat-bottomed plunger to plunge the sink drain. Place the suction cup at the end of the plunger over the drain so there's a tight seal, then pump the plunger up and down until the clog gets sucked away and your sink drains properly. If you don't have a flat-bottomed plunger, you can also try using a wire coat hanger to unclog your kitchen sink. Start by unraveling the coat hanger and bending the end into a hook shape. Insert the hooked end of the hanger into the drain as far as you can, and wiggle it up and down while twisting it to help break up the clog. If nothing is working, you may need to use a drain snake to reach further down into the drain. If your sink has a garbage disposal, try turning it on to see if that breaks up the clog. If all else fails, it might be time to call a plumber. If your sink is still clogged, read below for advice on how to drain the drain trap!
