How to Unclog a Kitchen Sink Drain in the Most Effective Techniques

Let’s start 👍

1. Use boiling water as a weapon

When grease, hair, soap residue, and other particles get caught in the drains, boiling water could be the best solution to break the obstruction. 👌

It’s the easiest fix and should be the first thing you do when cleaning your sink drain.

As simple as 1-2-3, here is what you need to do:

  • Take half a gallon of water to boil using your stove or kettles to warm the water.
  • Put the water that is boiling directly in the opening for the drain.
  • The faucet should be turned on to check whether the water is draining with a steady flow. If it’s not draining as fast or is sitting still in the sink, repeat the procedure.

Important note: Avoid this technique if your drain is connected to PVC pipes, since the boiling water may be able to melt or harm the PVC pipe.

When the water that is boiling doesn’t manage to clear the blockage after the second time then it’s time to switch to an alternative method.

In the end, you’ve got an unclean sink that’s just not able to handle the straightforward boiling water solution.

2. Make sure the Waste Disposal is Working

The next thing to do is to make sure that your trash disposal isn’t the cause of the issue.

A clogged garbage disposal can cause a blockage in your drain. Therefore, you should run the disposal for about a minute or so by running hot water to determine if it removes the blockage.

If it doesn’t then make sure that the appliance is shut off, and then check it to ensure it’s working properly.

If the appliance has run out of fuel and has automatically shut off then you’ll need to start it again by turning it off at the base.

The switch that turns off the base will usually be located on the bottom or side of the unit under the sink.

3. Plunge with a Plunger

There are three kinds of plungers: the traditional sink plunger with a flat bottom, the accordion plunger, and finally the toilet plunger that has an additional bell-end located at the bottom.

It is better to choose an elongated plunger for this task.

4. Baking soda and vinegar can help break it down

This method is a good alternative to chemical drain cleaners for blocked drains.

For your convenience vinegar and baking soda are common household products that you’re likely already to own in your home. 😊

Use these tips to allow the mix to perform its magic:

  • Take outstanding water from the sink by using the help of a bowl or cup.
  • Pour 1 cup baking soda into the drain. Use the spatula or spoon to force the powder into the drain, if needed.
  • Put one cup of vinegar into the drain’s opening.
  • Cover or place a stopper on the drain in order to seal the drain’s opening.
  • Allow the mixture to sit at room temperature for about 15 mins.
  • Uncover the cover, and then run hot tap water through the drain.
  • Make use of hot water for breaking apart larger clogs that are more powerful.
  • Like all unclogging methods, it isn’t going to guarantee a 99 percent chance of success.

However, if it looks like you’re progressing with the obstruction after having completed the steps, you can repeat the process to make sure you’re doubling down on the obstruction.

5. Vacuum Cleaner (Wet-Dry)

If you own a wet-dry vacuum in your home this is an excellent tool to clear the kitchen sink of clogs. 👌
Set the vacuum for use in wet conditions in accordance with the directions.

When you’ve got a double sink, you must cover the second drain hole exactly like the plunger method.

Put the hose on the drain to create an enveloping seal. The vacuum should be set to the highest setting in order to eliminate the obstruction.

The vacuum’s force will be sufficient to clear the obstruction.

It’s possible to be successful but it’s likely only worthwhile if you already have a vacuum that is wet dry readily available.

In any case, stick to the other methods described below.

6. Use a snake from a plumber

Sometimes referred to as an auger, the plumber’s snake can be described as an efficient tool to remove clogs that have accumulated further down the drainage system underneath the kitchen sink.

You’ll need to take apart the drainpipe and P-trap which runs beneath the kitchen sink, exposing a “stub pipe” or “stub out” which runs behind the cabinet’s wall.

This is when you place the snake inside it until there is resistance. dislodge the clog.

7. P-trap should be cleaned

The P-trap is an elbow-shaped pipe beneath the sink. If it becomes blocked by grease and food particles.
It is possible to take it off and clear the gunk that’s causing the obstruction.

How to Clean the P-Trap in the Kitchen Sink

  • Before starting, make sure there is a bucket beneath the P-trap in order to collect the water that has gotten backed into your sink.
  • It is then necessary to unscrew the connections between the wall and the pipe.
  • Clear the P-trap and inspect it for any waste.

If the blockage isn’t located in the P-trap you’ll need to unblock the drain using the plumbing snake.

8. Cleaning chemicals should be used

If your sink is equipped with garbage disposal, I would strongly recommend not employing chemical cleaners, as they can damage the blades and then spray back into the sink.

I would not suggest the use of a chemical cleaner in liquid form when you’ve got a major obstruction rather than an issue that drains slowly.

If you make use of chemicals, there is always the possibility that toxic chemicals could get backed up in the sink as well as stagnant water, and could cause a health risk.

The kind of cleaner you purchase will be based on the kind of thing you think might cause the obstruction.

Most commonly those clogs that are caused by bio-matter need the use of a cleaner that is more acidic, and greasy clogs should be treated with alkaline cleaners.

Always be sure to read the label and use the cleaner according to the directions.

Chemical cleaners could be hazardous when used improperly.

9. Make use of a coat hanger

If you don’t own an extension for a plumber’s snake then you can make use of the wire coat hangers as an alternative through straightening.

However, it will not be as long as a snake made of plumbing; however, it could be long enough to access certain blockages.

However, it’s worth trying even if you’ve tried everything else.

Put the straightened hanger wire to the sink drain in your kitchen.

Use a pipe and push it through or remove the blockage if you are able to get it out.

Be cautious that you don’t scratch the sink by using the wire.

To ensure that your sink is fresh and clean make sure you add equal amounts of baking soda and vinegar every day typically every other month or two.

For regular cleaning, it’s just about half a cup each. The mixture should remain for a while before pouring warm water through the drain.

It is also possible to use lemon juice to accomplish the same thing.

If you have garbage disposals, you can drop some slices of orange or lemon rind into the disposal and let it run for 30 seconds or so to crush it.

Allow the mixture to rest for five minutes before washing.

Naturally, it’s better to stay clear of clogs at the beginning.

If you’ve got an appliance for kitchen use do not overfill it with garbage.

Introduce items a little at a moment, and wait until they are crushed and are completely through prior to adding additional.

Be aware of what you should not put down your garbage disposal. Don’t ever dump bacon grease, coffee grounds or oils in your kitchen drain.

Make sure you flush lots of water through the drain after every use. It is essential to understand how to care for and maintain all of the plumbing components in your home and systems to ensure that everything is working smoothly.
