Some people put coffee grounds into the sink, thinking it would reduce the foul smell. But can coffee grounds go down the sink? What happens?
The value of pouring coffee grounds into the sink is one myth that is circulating online. Some people believe that this will minimize the sink’s bad odor. They don’t know that the only thing that can happen when they do this is clogging their sinks. Their drains will soon be blocked with ground coffee if they keep doing this.
Coffee is not like your usual food. When you put water on coffee grounds, they clump together instead of breaking down. So, if you pour coffee grounds down your sink, they will build up inside the drain over time. This will create clogs that can inhibit the free flow of water. You should always put coffee grounds in the garbage can instead of the sink.
Read on to learn more about the consequences of putting coffee grounds down the sink.
Can Coffee Grounds Go Down the Sink?
People Believe the Practice Can Minimize Foul Smell from the Sink
Some people believe in the value of putting coffee grounds down the sink they share in their posts on the internet. They believe this practice will minimize the foul smell coming from their sinks.
However, the only thing that can happen if you do this to your sink is it will get clogged. If you continue doing this to your sink, coffee grounds will clog the drain.
Clumps Together When Wet
You see, coffee grounds are not the same as regular food. When you put water on them, instead of dispersing, they clump together.
Can Form Into Big Lumps Causing a Clogged Sink
So, if you keep on putting coffee grounds into your sink, they will build up inside the drain. They will eventually form into big lumps of coffee grounds. Finally, you will end up with a seriously clogged sink where wastewater cannot freely drain.
The only place you can safely put unwanted coffee grounds is in the garbage can. Garbage disposals can’t even process coffee grounds. These machines are not designed to handle these small and fine but tough coffee grounds.
Can Coffee Grounds Go Down the Garbage Disposal?
Coffee grounds are too fine for the mechanism inside the garbage disposal machine to process. They could even jam the system of the machine.
Use Coffee Grounds as Compost or Throw Them in the Garbage Can
The best way you can deal with useless coffee grounds is to throw them in the garbage can or to use it as compost.
If it’s the first time you pour coffee grounds into your sink, it may not get clogged immediately. However, don’t think that just because it didn’t happen at first, you can continue doing it whenever you want.
You see, water is not able to break down coffee grounds. Although they are very fine, they are still tough as nails.
In addition, when they come in contact with fats, which you usually pour down into your sink, they stick to each other. This is the perfect combination that will surely clog your sink.
Use Them as a Scrub
Some people also transform these ‘tough as nails” coffee grounds into a scrub that they use whenever they take a shower. Some drop down the shower drains as they use the coffee ground scrub. They could also accumulate, build up and clog the shower drain eventually.
Why Coffee Grounds Can’t Go Down the Sink
Can Combine with Grease to Form Sludge
People will only stop doing what they are used to if they are given valid reasons why they shouldn’t do what they are doing.
Coffee grounds will clog your sink since they cannot break down like other foods. When combined with grease or fat, they will become part of the drained sludge, which is very difficult to remove.
Other Reasons Behind a Clogged Sink
Don’t be mistaken. Coffee grounds are not the main reason why your drain is blocked. The primary reason is the accumulation of grease and fat on the drain pipe. You also wash down their grease contents when washing your kitchen utensils, dishes, and plates.
These fats stick and thicken to the walls of the pipes. The fats and grease on the drain pipes accumulate as you continue washing your dishes and pans in your sink.
Now, when you flush down coffee grounds in your sink, the fats, and grease on the walls of the pipe will catch them and will never let them go, no matter how high the pressure or hot the water is.
If you do this continuously, the number of coffee grounds on the fat and grease inside the pipe walls will build up over time. In due time, you will have a blocked drain pipe. Then you will have a problem with a non-draining sink.
Other Food Wastes That You Should Not Pour Down the Sink
There are other food wastes that you shouldn’t pour down your sink, including the following:
- Starchy foods such as potato peels, potatoes, rice, and pasta.
- Oil, grease, and other types of fats
- Non-food items include sponges, wood splinters, cigarette butts, small metal pieces, and glass shreds.
- Items with fibers such as fish skins, egg shells, celery, and banana peels.
Are Coffee Grounds Safe for Septic System?
Need to Pump Out the Debris in the Septic System More Often
Some believe pouring coffee grounds down the sink is not a big deal.
However, suppose you will consider that some communities live on properties using a septic system. In that case, it is essential to know that the coffee grounds that you pour down your sink won’t break down and won’t eventually affect your area’s septic system. Isn’t that a big deal?
Repeatedly pouring down your unwanted coffee grounds down your sink will continue the buildup of the layer of solids that do not decompose in the septic system. If you insist on doing this, you need to pump out the debris in your septic system more often.
Waste of Money
Undoubtedly, pumping out accumulated debris in a septic system involves a lot of money. This is a waste of money, considering that you can avoid it by just throwing your unwanted coffee grounds on the ground – like compost.
Coffee Grounds Can Disrupt the Decomposition of Waste
Coffee grounds can also skew the pH of the septic system. They will acidify it. When this happens, there will be an adverse effect on the function of the bacteria inside the septic system or septic tank. You will disrupt the decomposition of wastes inside the tank.
So, as you can see, pouring your wasted coffee grounds is a big deal – especially if you do it without any concern for your environment. If you accidentally do it, then that’s fine. But if you do it constantly because it is convenient, that’s a big problem.
Best to Throw the Coffee Grounds in the Garbage Can
If you throw coffee grounds down the sink instead of the garbage can, you will have a problem with your blocked sink and drain. You will have to call a plumber to correct the issue, or you may have to watch YouTube videos on how to unclog your drain.
Again, can coffee grounds go down the sink? Coffee grounds tend to clump together in the water. So, over time they can accumulate and clog your sink. You can throw them in the garbage can or use them as compost.
Is It Safe to Dump Coffee Grounds Down the Sink
Many thought pouring down coffee grounds on their sinks won’t do much harm. Some have even praised the ‘good’ effects of the coffee grounds on the drain. They thought that they were keeping the pipes smelling fresh by doing it.
However, after giving it sufficient time, they discovered that that’s not the case. Those who tried to remove the coffee grounds from their sinks found that these little things could be sticky and grippy.
They also discovered that these fine coffee grounds formed an impenetrable and very stubborn blockage in their drains over time. Not even garbage disposals can handle these coffee grounds.
They are too fine for the garbage disposal to process. It is much better to dispose of them naturally – throwing them in the garbage can or using them as compost.
How to Fix a Clogged Sink From Coffee Grounds
