Things You Should Never Drain In Your Kitchen Sink

Without even realizing it, we might be the culprit of clogs in the sink. We have a habit of leaving our waste in the sanitary drain when we wash our dishes. Many of us dump our small table scraps into our kitchen sink at the end of our meal, where they mysteriously vanish when the water is turned on.

We do the same thing with things that appear to be harmless to us, yet we are most likely making a major mistake!  Putting all of your dirty things in the sink not only results in costly plumber visits, but it also harms the natural ecosystem, particularly rivers, lakes, and oceans. Here’s a list of food items that homeowners should put in the bin rather than send down your sink pipes.

Egg Shells

Eggs shells can be very hard to sink blades, reducing the life of the appliance. Also, the membranous found in the shells’ inner layer wraps around the grinding apparatus and can cause motor burnout.

It’s better to dispose of them in dustbins. You can also store shells, which are in good condition for Easter time.

Expandable Foods

Expandable foods like pasta and rice easily slip down the sink. Rice grains swell as they soak in residual water in the sink pipe gradually blocking it. Pasta is composed of semolina content that makes it stick to pipes causing huge plumbing problems in future.

Use kitchen strainer, sieves or colanders to collect chunks of expandable food items and put them in the garbage disposal only.


Flour makes gummy stuff when mixed with water. It coagulates and hardens inside the pipe and causes huge plumbing issues.

Coffee Grounds

Coffee grounds do not harm the draining system. Rather these help to absorb the odor caused by blocked sink. But coffee grounds accumulate in the pipe and clog it. Therefore, it is suggested trashing the coffee grounds in a bin before washing your coffee mugs. Coffee grounds are a natural deterrent to many garden pests. To keep unwanted bugs and vermin out of your garden, simply sprinkle them around.

Cooking Oil

Most of the people tend to drain their waste cooking oil, mayonnaise and salad dressings in their kitchen sink. This is the most common cause of drain blockage. Since cooking oil is sticky in nature, it sticks with the pipe and easily mixes with other debris, thus easily coagulating the drainage.

Butter and Margarine

Melted butter and margarine collect and build up in the draining system eventually creating water resistant barriers.

Produce Stickers

Produce stickers found on the food items are made up of plastic material, which is hardly soluble in water. However, these stickers fall off easily in the sink and can block screens and filters down the line.


Though there is no danger of draining pharmaceuticals in the kitchen sink, medication mixed with water are not good for human, animals and for plants. Some of the chemicals included in those drugs cannot be filtered, and they can still harm people and the environment. Always dispose of expired drugs at your local pharmacy, since they have access to adequate disposal facilities.


When grease is hot, it is liquid, but it freezes as it cools, posing a serious threat if spilled down the sink. It then adheres to the pipes or clumps together, causing them to get damaged or clogged quickly. To dispose of it, place it in a container and throw it away once it has hardened. Finally, fats from frying meats, such as oil, mayonnaise, and butter, might clog your pipes.


Even the most advanced garbage disposal system will fall short when it comes to bones. The occasional fishbone is alright, but larger bones from poultry and other animals will blunt the machine’s blades and weaken the mechanics. It will become substantially less efficient much sooner than it should be as a result of this. Because bones are rarely entirely broken down, they are prone to clog pipes, preventing other liquids from passing through.

Food Waste

You can carve smaller, softer food scraps, however, the majority of food scraps and bones in particular should never go down the sink. This can be difficult, especially if you wash your dishes by hand rather than in a dishwasher.

The best way to avoid accidentally washing food down the sink is to keep your sink rack on at all times. This filters out the larger pieces so that you can place them in your compost bin instead.

Potato and Potato Skin

The starch substance found in potatoes turn them in the gummy glue that coagulates the moving parts of the draining system, ultimately damaging them. Instead, peel potatoes in a strainer or colander and dispose of the useless stuff in the bin.

Cleaning Products

While most cleaning solutions come in liquid form, they are not intended to be dumped down the sink. They include chemicals that can be dangerous to you and the environment, just as pharmaceuticals and paint. Even after being treated, most of these goods contain contaminants that are still present in the water. These substances should be handled with care and disposed of properly, not flushed down the toilet.

Raw meat easily wraps around the blades, making the motor difficult to grind up. It’s good to bag up disposable meat and throw it out to the trash bin. Never put meat into your in-house garbage disposal as it may stink badly.

Stringy, Fibrous Foods

Any food like corn husks, garlic ends, onion peels, lettuce, and more with stringy parts or thin skins does not fare well in the kitchen drainage. These easily tangle around the blade motor making it work slowly.

How to Know Whether Your Kitchen Sink is Clogged

The good news is that detecting a problem with your plumbing is usually simple. First, whether it’s your tub or a kitchen or bathroom sink, you’ll notice that water is draining slower than usual. If you leave it alone, it will eventually cease draining completely, indicating that the clog has blocked a section of the entire pipe.

The bad news is that by the time one of your pipes reaches this point, the issue has most likely been brewing for months, if not years. Whether you realize it or not, you’ve probably been putting all sorts of alien materials and stuff that don’t belong down there into your plumbing.

If you see some cracks in the foundation, it’s most likely due to a blockage of drain. The severity of the problem is determined by the crack’s width. If the crack is less than a centimetre long, you can simply contact a professional who will fill it with epoxy injection. A crack repair can cost anywhere from $250 to $1000, depending on its location. If the crack is large enough, your foundation will almost certainly need to be renovated.

Why You Need To Regularly Inspect Drainage System

It is recommended to inspect your drainage system at least once a year. This simple operation allows you to verify that the installed system is of good quality, in good condition and that it effectively protects your home from moisture or possible water infiltration.

The cost to fix a French drain problem is much higher, as it involves more work and may require the expertise of a structural engineer. Doing nothing about French drain problems can have significant consequences on the structure of your building. Be sure to call a French drain expert.

It is possible to carry out an inspection of the drainage system by camera. Thanks to this test, it is possible to easily determine the slightest anomaly in the drainage pipes that could lead to a blockage of the drain. So, consider performing a drainage inspection of your home at the same time as a cracked foundation inspection.

Why does a drain pipe clog?

A clogged drain can occur for a variety of reasons. To begin with, it can simply deteriorate over time. Dirt, sand, and mud can clog the drain over time, preventing water from flowing properly. Second, there’s a chance it’s a bad installation.
Obstructions are frequently caused by installation flaws. Water will not be able to flow freely if the drain is improperly placed, and it will gradually fill with sediment and get stopped.

Hair can clog drain pipes as it washes down the drain in the shower or while washing your hair in the sink. Combing and trimming your hair over the sink, in addition to washing it, will eventually clog the water drain. Another culprit is soap.
Soap by itself isn’t often an issue, but when it’s mixed with hair and other substances, it can solidify and clog your drain. The only paper or hygiene product that should be flushed down any of your drains is toilet paper, and even then, you shouldn’t flush very often. When you see the word “flushable” on a wipes or paper product container, you should be cautious.

By utilizing a drain screen, you may reduce the amount of hair that enters your pipes. Brushing your hair before stepping in the shower will also help prevent hair jams in your drain if you have long hair. It’s also a good idea to hire a professional plumber to clean your pipes once a year to keep them clear and healthy. This will help your pipes, drains, and plumbing system last longer.
