When it comes to freeing up the sink pipes, the only tool that instantly comes to our help is a plunger. 

Whenever you notice murky water coming through the sink simply put the plunger over the sinkhole to create a vacuum inside. 

Now tightly hold the plunger and start moving it back and forth until the pressure brings mobility to the clogging inside and starts breaking it, echoing an empty sound.

Let us warn that this process may take time depending on the accumulation and your skill of using the plunger. 

So till you are hearing the convincing sound of the blockage getting washed away from the drainage pipes, you have to patiently repeat the process.

But once you get the desired result, instantly run down the hot water stream from the faucet for a satisfying experience.

Vinegar and baking soda mix is a magical elixir that can solve half of your domestic problem including unclogging the double kitchen sink.

These are the must-have kitchen items that have proven to be 100% effective in getting rid of junk accumulation in the sink and pipes. 

If your sink is jammed with food particles and other foodstuffs that you carelessly dumped into your sink, here’s what you can do to unclog it:

  • Pour a cup of baking soda into the sinkhole and use a plumber’s snake or metal hanger to settle it deeper.
  • Wait for few seconds (approx 10 to 15 seconds)
  • Now follow the same method using a cup of vinegar and seal the drain opening. 
  • Now, wait for few minutes (10 minutes approx) to let the mix unclog the junk.
  • Now flush them out with running water.  

For best results use hot water instead of tap water.

You can try this once a month to keep the pipes functioning smoothly.

Use A Drain Cleaner To Unclog A Double Kitchen Sink

When you don’t want to go the tough way, drain cleaners come in handy in getting rid of the stagnant debris.

You can either use the commercial ones or make your own using baking soda and vinegar as mentioned before. 

However, there are few drawbacks of using chemical cleaners as they might remove the junk easy breezy but will damage the pipes when exposed to such corrosive liquid over a longer period.

Despite few disadvantages, these chemical cleaners are a convenient option to use during an emergency when all your DIY methods have failed or when you are too occupied with other work.

To make the best use of drain cleaners pour a sufficient amount of the liquid as needed in the sinkhole (read the instruction at the back of the bottle or packaging). 

Then wait for at least 30 minutes till the time you manage other chores and then rinse it down with a normal or warm stream to clear the clog.

With Metal Hanger or Plumber’s Snake

With Metal Hanger or Plumber's Snake

This method is a professional’s craft and even you can do it and master it over time without getting irritated.

The thought of unclogging a double kitchen sink all by yourself can be a bit demotivating, but with some patience, you can easily get through with it.

If you do not have a plumber’s snake, you can use your thin metal hanger as a substitute to unclog your sink.

You can apply water force to flush down the garbage but this easy hack will only remove the tip of the iceberg while the huge pile of the clog is underlying deeper in the pipes that need a push to breakthrough.

This is when you will need a metal hanger or a zigzag hook called a plumber’s snake. 

Whatever you use the process is the same:

  • Skilfully put metal hanger/plumber’s snake through the hole and move down deeper as much you can. 
  • Remember to rotate the plumber’s snake/metal hanger thoroughly to break down the debris stuck in the pipe walls. 
  • Once you feel less resistance down the pipe, apply water force to flush the filth through the outlet.
  • Repeat the process again if you are not satisfied.

Use Baking Soda, Salt & Hot Water To Unclog A Double Kitchen Sink With Disposal

If you are lacking any of the easy ingredients mentioned above, you can still rely on the humble table or rock salt whatever available in your vicinity, and the steaming universal solvent.

Hot water is extremely effective in breaking down the clogs when mixed with a proportionate amount of salt and baking soda. 

This is one of the most reliable ways of clearing the junks stuck in the drainage pipes of your double kitchen sink with disposal.

There are a lot of ways you can unclog the sink but what we insist on is instead of cleaning the mess that has accumulated as a result of ignorance why not apply these simple DIYs often to keep the pipes freeze-free. 

For best result rinse thoroughly the hot water stream along with some salt every time after you assembles the kitchen chores.

Disassemble P-trap To Clean The Clog

Disassemble P-trap To Clean The Clog

It may happen that even after religiously following each of the ideas your kitchen sink is still malfunctioning. 

So what’s left that needs your attention? 

Get down to have a look at the curved area known as P-trap connecting the pipe.

Now before you get your hands straight in removing the P-trap get a bucket first and put it right under this section so that the floor stays safe from getting wasted. 

This curved area might be holding the filth which is not allowing the water to pass.

Once you disassemble the trap you will notice how much junk this section can hold and interfere with the normal functioning of the double kitchen sink. 

Place the pipe over the bucket to run water through the sink for few minutes till the blockage is removed completely.

Once you are satisfied assemble the P-trap again. 

We recommend that you go with this method only if you are confident enough to disassemble and assemble the P-trap on your own or else you will end up spending more if something goes wrong. 


Why kitchen sink gets clogged?

A clogged kitchen sink is a common problem in every household. 

While dialing a plumber is the only way to fix the issue but you should also be cautious of what you are putting down in a kitchen sink garbage disposal.

Kitchen sinks bear daily abuses of grease and dirt flushing down that eventually form a sticky layer on the wall of the pipes. 

And when you ignorantly let the food particles like potato peels, eggshells, fish bones, etc. pass through the sinkholes on regular basis, it creates a solid blockage in the pipes starting with gurgling noise and then flooding the sink with the filth.

Let’s have a look at the food items that can harm your double kitchen sink.


Things You Should Not Put Down A Double Kitchen Sink Garbage Disposal

Chicken/Fish Bones or Any Other Animal Bones

To prevent the kitchen sink from getting clogged frequently, you need to avoid some unavoidable mistakes that you unknowingly do on a regular basis. 

If you want the kitchen sink to perform smoothly, stop throwing any fish or animal bones down the sinkholes from now on. 

This is one of the main reasons why sinkholes often get jammed.

No matter how durable the garbage disposal is, it cannot grind the harder substances like bones and ends up clogging the flywheel. 

The bones in the process of struggling their way out through the pipes severely damage the walls, calling for frequent replacements and maintenance. 

So, next time before washing your dishes safely dump the bones in a separate bin to put a check on this unavoidable habit.

Outer Layer of Onion, Onion Roots & Foliar Stem

This is one common blunder that we often commit in a hurry while cooking and managing daily kitchen chores. 

The outer scaly layer of the onions that you ignorantly dump down the pipes can clog the kitchen sink garbage disposal over time.

If your kitchen sink often makes the gurgling noise, then chances of the onion peels that you have flushed down the sinkhole might be blocking the paths for other filth to pass through. 

This is obvious and is a result of your sheer ignorance.

So what can you do to stop dumping the peels directly down the sink? 

The simplest solution is placing a bin under the sink or somewhere in the kitchen so that you can easily spot it as a reminder before repeating the mistake. 

Potato Peels

Potatoe peels create the same ruckus as the outer layer of the onion when you dump them through the sinkholes. 

So every time before starting with your daily vegetable slicing and dicing, keep a trash can ready beneath the countertop to dump the peels and other waste. 

If you have made it a habit throwing potato peels in the garbage disposal, you should do all the chopping somewhere else in the kitchen and use the sink only for washing. 

The starchy peels not only stain the sink badly but also creates blockage down the pipes only to make your kitchen life miserable.

So, avoid dumping potato or any other vegetable peels down the sinkhole, if you want to ensure a lasting normal functioning of your double kitchen sink disposal.

Egg Shells

While your newly installed garbage disposal comes with the claim of crushing down almost everything but few wastes like eggshells are not meant to be disposed of easily and can clog the plumbing.

You may think that the fragile shells can easily pass through the pipes but the fact is they are sticky and has a profound chance of getting piled up and create a jam down there. 

Surprisingly, many even assert that the calcium-filled abrasive edges of the shells can sharpen the disposal blades to enhance their performance, while others have dismissed the claim citing that the shell membrane can cause build-ups and ruin its efficiency.

Putting aside all these never-ending claims, we recommend using the under sink bin than dumping the eggshells in a garbage disposal.

Fruit Pit & Seeds

Are you pissed of with your kitchen sink often getting clogged for no reason? 

Think twice because unconsciously you are blatantly throwing the fruit seeds and pits down the sinkhole and complaining about this frequent clogging.

Kitchen sink garbage disposals are meant to make your kitchen life simpler so don’t ruin its efficiency by putting down harder things like fruits pits and seeds.

When you ignorantly put such solid objects in your kitchen sink on a regular basis, thinking they will easily pass through, they instead block the pipes and damage both the pipe walls and disposal blades.

So from now on, before munching on your favorite fruit, keep aside a plate to collect the seeds and pit and discard them later in the bin. 

Cooking Oil, Fat & Grease

This is what most of us repeat every time after cooking to empty the hot oil off the pan directly down the sink. 

And this one common blunder is enough to clog your kitchen sink and the disposal mechanism.

We often pour leftover hot oil and fat into the sinkhole assuming they are liquid and will easily pass ignoring the fact that they will turn into solid grease after cooling down.

Oil, butter, and fat when washed down the double kitchen sink pipes creates a sticky layer inside the pipe walls. 

This greasy layer traps other particles coming down the way leading to major clogging down there. 

So, if you want your kitchen sink disposal to function smoothly, then strictly avoid pouring fats and oils down the sinkholes.

Cooked Pasta, Cooked/Uncooked Rice & Oats

Straining cooked pasta and rice down the sink is a common habit that eventually contributes to clogging the system. 

Surprised? 

You shouldn’t be after knowing that the strained pasta water has the same properties as the potato peels to create a thick starchy layer inside the pipes. 

Throwing cooked or uncooked rice down a garbage disposal is also one such mistake that we do even after knowing that rice has a natural tendency to soak water. Same is the case with oats. 

So when the rice grains or oats get accumulated inside the pipes, it absorbs all the fluid coming down the way and becomes fluffier to create a massive blockage.

To prevent this from happening, you can strain the rice and pasta water in a separate bowl and empty somewhere safer like in your garden as an organic fertilizer.


Final Thoughts

Whether you want to unclog a double kitchen sink with disposal or that is full of water the DIY ways we have mentioned above will save your day if you follow the steps.

To ensure the smooth functioning of a double kitchen sink you need to pay some extra attention to its maintenance and that can be done with some discipline.

Make sure you are not dumping anything and everything in the kitchen sink as some of the food particles like eggshells, potato peels, rice, pasta, oats, seeds, etc. get stuck in the pipes and eventually lead to clogging.

Even after being careful if you come face to face with a clogged double kitchen sink,  instead of calling for professional help, try any of our listed easy-to-follow hacks and save both your time and money from getting wasted.
