Things That Should Never Go Down Your Drain

Clogged drains are messy, unpleasant, and sometimes expensive to fix. The good news is that many drain problems are preventable. One of the easiest ways to avoid blockages is simply being careful about what goes down your drains.

Often the first sign of a developing clog is a foul smell coming from the drain. If you notice that familiar odor, it may mean food, grease, or debris is starting to build up in your pipes.

Here are some common things that should never go down your drain.

Food and Kitchen Waste

In general, food scraps should not be washed down the drain. As food breaks down, it can create unpleasant smells and contribute to clogs.

Some items are especially problematic:

• Coffee grounds – When wet, coffee grounds clump together and can easily form blockages.
• Egg shells – Their porous texture can trap grease and food waste, helping larger clogs form.
• Fats, oils, and grease – These substances solidify as they cool and can form large masses known as “fatbergs.”
• Flour – Flour mixed with water creates a glue-like substance that can stick to pipe walls.
• Mashed potatoes – Similar to flour, they can create thick, sticky buildup inside pipes.
• Pasta and rice – These foods expand when exposed to water, increasing the risk of blockage.
• Bones – Even with a garbage disposal, bones can jam the system and dull the blades.
• Produce stickers – These small labels can stick to pipes and strainers, trapping debris.
• Hot wax – Wax hardens as it cools and can create solid blockages inside plumbing.

Bathroom Items That Cause Clogs

Bathroom drains are also common locations for plumbing blockages.

• Hair – Hair can collect in pipes and trap soap residue and other debris, forming thick clogs.
• Cotton balls and cotton swabs – These items expand when wet and can quickly block pipes.
• Dental floss – Floss is not biodegradable and can accumulate in pipes over time.

Even flushing certain items down the toilet can cause problems. Cotton swabs, for example, can wedge sideways in the drain and trap other waste.

Hazardous Materials

Some materials should never be poured down the drain because they can damage pipes or contaminate the environment.

• Solvents and corrosive materials – These substances can damage plumbing and erode pipe surfaces.
• Flammable or explosive liquids – These can react with other materials in pipes and create dangerous situations.
• Paint – Many municipalities consider paint hazardous waste because of its chemical content.
• Medications – Water treatment systems cannot fully remove many pharmaceutical chemicals.
• Harsh cleaning chemicals – Strong chemicals can harm pipes and may impact water systems.

Hazardous household products should always be disposed of through proper waste programs in your municipality. Many cities provide designated drop-off locations for these materials.

Preventing Drain Problems

Many plumbing clogs happen because of convenience. It is easy to think “just this once” when rinsing something down the sink. Unfortunately, repeated small actions can eventually lead to a stubborn blockage.

Being mindful of what goes down your drains can significantly reduce clogs and unpleasant odors in your home.
