Although pretty common, dealing with clogged sinks can be frustrating, especially when entertaining guests at home.

It usually occurs when foreign objects get trapped in the kitchen or clogged bathroom sink drain, including soap scum, hair, food scraps, tissue, etc. People often do not take this problem very seriously, but it can lead to more complicated issues later if not resolved in time.

Unclog Sink

A clogged sink can cause plumbing leaks and backup wastewater through the drain pipe. Fortunately, a few steps exist to deal with this problem quickly and prevent the situation from worsening.

If you want to know how to unclog a sink, here are seven steps you should try!

7 Steps To Unclog Your Sink

1. Using Boiling Water

Soap scum, hair, and other substances trapped in the sink drain can be removed if you pour boiling water down the clogged drain. To do so, boil around 2 litres of water using your stove or kettle before pouring boiling water directly into the sink.

Check whether the kitchen sink is draining properly by turning on the faucet and repeat the process if it is not. However, avoid using this method with plastic pipes since the boiling water can melt them.

2. With Vinegar And Baking Soda

Another method you can try is using a vinegar and baking soda mixture, a natural drain cleaner. These household items are easily available and safer alternatives to chemical drain cleaners, but they create a reaction powerful enough to melt the clog.

If your sink has standing water, remove it using a bowl and pour about ½ cups of baking soda into the drain. Then, pour the same amount of white vinegar into the blocked sink drain, using a spoon or spatula to push it into the pipeline. Finally, cover the opening with a drain stopper.

This will ensure the reaction is forced downwards through the pipes to where the sink clog is. Let the mixture sit for 15 minutes before removing the cover and pouring about 2 litres of hot water down the drain. You can add more baking soda and vinegar before rinsing with boiling water.

3. Unclogging With A Plunger

You can also use a plunger to remove the clog; a flat-bottomed plunger or a toilet plunger is most suitable. First, fill the sink with hot water to create a tight seal, and hold the plunger upright above it.

Then, plunge vigorously to force the water into the clogged drains and continue for about 20 minutes. Once done, remove the plunger to see whether the water is draining, and if it is, continue the process until the water starts flowing freely.

4. Cleaning The P-Trap

The sink has a P-trap to trap impurities and prevent hair, soap residue, coffee grounds, and other debris from entering the pipes. If the trap is blocked, water can drain slowly or stop draining altogether.

The P-trap can be easily removed and cleaned to resolve this issue. However, doing so can be a bit messy, so wear goggles and gloves.

Place a bucket underneath the sink to catch debris from the pipe, and use a pair of slip joint pliers to loosen or unscrew the slip nuts. Once the nuts are removed, you can disassemble and clean the trap using a wire brush.

Finally, wash the trap with hot tap water and reattach it to the sink before checking whether it is draining properly.

5. Using A Coat Hanger

An old wire coat hanger can be handy for removing clogs caused by hair, tissue, and other substances. However, you must straighten out the hanger while creating a hook at one end to insert it into the sink drain.

Carefully slide the hooked end of the hanger into the drain while pressing it to the side. This will prevent sink clogs from being pushed down the piping.

If you feel resistance, try hugging the materials causing the clog and pulling them up slowly. Once the clog has been removed, run hot tap water through the drain opening for a few minutes to check the drainage.

6. Checking The Garbage Disposal

A kitchen sink with a garbage disposal system may have food scraps or other items trapped inside, causing the clog. In such situations, the disposal system may fail to turn on, and you will have to reboot it using the switch provided on the side.

Alternatively, a humming sound may indicate a broken or jammed disposal, in which case disconnect the power to remove the clog.

7. Using A Plumber’s Snake

For the most stubborn clogs, you must use a plumber’s snake, a handy tool that can be bought from any hardware store. You can also get an electric plumber’s snake, which is even more effective, provided you don’t use too much force since that can push the clog further down the drain.
