11 Things You Should Never Drain In Your Kitchen Sink

This post is a wake-up call to those who thoughtlessly dump everything in their kitchen sink. Putting all your messy things in the sink not only calls for expensive plumber visits, but it also damages the world’s natural environment, especially 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.

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. If you have expired medications, put them in the trash bin, preferably sealed.

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.

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.
