Peels And Rinds

An important piece of information is to scale back on what you put into the sink. Why? Why not! You’re either being a bit lazy not to dispose of fruit rinds and peels in the garbage disposal because it’s just too far, which is understandable. After all, we have all been there. And I say get a temporary bin in the kitchen for waste that could clog your sink.

Hair clumps up and embeds itself into a stinky mass of magnet that only attracts dried soap and more hair. This bunch of tangled hair is common for clogged tub drains and bathroom sinks. 

The pipe walls catch the hair clumps on their way down the sink, and as more pressure from the running tap goes down the sink, the hair clump together. It becomes tougher and resists water flow causing the sink to be clogged. Ways out include;

  • Using sink guards that collect the wet hair
  • Installing a pipe snake to free up the mass 
  • The fastest way out is by installing a drain straining device that collects the hair


There’s a story about eggshells cleaning and sharpening the blades of the garbage disposal, well this is a myth, and it does the entire opposite. Eggshells will create trouble for the garbage disposal blade, and the fragments of the eggshells will clump up together and clog the filter, and if a lot of these clumped up eggshells get down the drains, they’ll clog your sink too.

Damaged Pipe

Built-up rust from old pipes, dented pipes, worn-out pipes that can lead to blocked water flow can be reasons for a clogged sink. Poorly repaired plumbing, like not fastening the pipes securely, can cause the pipes to shift over time and can also clog your sink. 

Your best bet is to install new pipes as a replacement and ensure they are securely fastened. You must also ensure that they are not in places easily damaged.

Coffee Grounds

You might think pouring your grounds down the drain is one harmless disposal since the grounds are in powdery form, but they are only harmless if your drains are consistently cleaned. A sink with a sludge built up can be easily clogged when coffee grounds keep pilling until a form of tough grounds is formed. 

Starches And Fibrous Food

Did you know starchy and fibrous foods expand in the garbage disposal? These foods include celery, corn, potatoes, corn husk, asparagus, rice, and pasta can expand in the garbage disposal. Their expansion will ultimately distort the blades of the garbage disposal. Then, the sticky paste from starch solidifies in the pipes and clogs the sink. 

Your oatmeal and mashed potatoes leftovers become sticky and hard when left for too long and will become like this in your sink. A must-know to avoid situations like these is to entirely avoid disposing starch down the drain and limiting your garbage disposal for only crumbs disposal.

Cottom Swab

Cotton swabs and any cotton-like material are can only absorb water but cannot be dissolved by water, and over time, if continuously disposed of in the sink, it will cause it to become clogged.

Wipes And Towelettes

If it isn’t toilet paper and claims surrounding it say it’s flushable, do not dispose of it in the toilet and through the grinds of the sink. When shredded, they become worse and will begin to collect other waste.

A Stuffed P-Trap or J-Trap

The P-trap is the pipe’s bent part located directly under the sink; it joins the sink’s drain to a larger drain pipe.
