A clogged kitchen sink can be one of those problems you don't want to encounter, as it can fill up the sink with foul-smelling water, restrict your use of the sink and even affect your garbage disposal and dish washer. If you notice that water isn't flowing smoothly down your kitchen sink, you need to ensure that the problem isn't affecting other drains. If your toilet and bathtub drains are also clogged, you may have an obstruction deep in your sewers and will have to call in a plumber to fix the issue.
However, if only the kitchen sink is affected, you may be able to unclog it using one of the methods discussed below.
Use hot water or vinegar solution
Grease in the drain pipes is often the main source of a blockage in your kitchen sink. Clogging caused by grease or fat deposits will typically not block your sink completely, but you will notice that water flows down very slowly.
Try pouring a few bowls of boiling hot water to dislodge the clog and improve water flow. If this doesn't work, try pouring a few cups of vinegar solution in the sink. You will notice an acidic reaction as the vinegar breaks down the clog. Top this off by pouring some hot water to flush off any residual debris. Alternatively, you can mix salt and baking soda in a bowl of warm water and pour it in the sink. Leave the solution to work overnight and then pour a few cups of hot water into the drains the following day.
Using commercial cleaners may unclog your sink, but it could also corrode drain pipes, causing a plumbing disaster. For a partially clogged sink, hot water, vinegar or baking soda solution are essentially much better than commercial cleaners.
Use a plunger
If the above methods fail, a plunger is your best bet. For this task, you need a small plunger that will sit firmly on the sink flange. Add water to the sink until the plunger is submerged so it can generate enough pressure to remove the obstruction in the drains. Use forceful, repeated plunges until water starts flowing smoothly down the drain.
If you have a sink with two bowls, you may find that plunging one side doesn't work, as the pressure generated by the plunger will usually get diffused by the pipes on the extra sink and leave the clog unaffected. For plunging to work, you have to ensure that the second bowl is tightly sealed with a stopper.
