1. Oils and Fats: Avoid Clogging with Proper Disposal

Pouring oils and fats down the drain is a common mistake. While they’re liquid when hot, oils and fats solidify as they cool, coating the inside of pipes and eventually leading to blockages.

  • Prevention Tip: Let oils and fats cool in a container, then dispose of them in the bin. Avoid pouring any fatty substances, such as bacon grease or cooking oils, down the sink.

Proper disposal of oils and fats prevents thick deposits from building up in your pipes, keeping water flowing freely.


2. Coffee Grounds: Dispose of Grounds in the Bin

Many coffee lovers unknowingly contribute to drain blockages by rinsing coffee grounds down the sink. Unlike instant coffee, ground coffee doesn’t dissolve in water and tends to accumulate in pipes.

  • Prevention Tip: Always dispose of used coffee grounds in the bin or compost, rather than washing them down the drain.

By keeping coffee grounds out of your sink, you prevent clumps that could obstruct your drainage.


3. Hair: Brush and Trap to Prevent Hair Clogs

Hair is one of the leading causes of bathroom drain clogs. When it enters the pipes, it often mixes with soap residue, creating stubborn clogs that restrict water flow.

  • Prevention Tip: Brush your hair before showering to catch loose strands. Use a drain strainer to catch any hair that does make its way to the drain.

Regularly cleaning hair from strainers can prevent significant clogs from forming deeper in the pipes.


4. Baby Wipes: Bin It, Don’t Flush It

Even though some wipes are labelled “flushable,” baby wipes are notorious for clogging drains. These wipes do not break down like toilet paper, and they easily stick together to create blockages.

  • Prevention Tip: Always dispose of baby wipes in the bin, even if the package says they’re flushable.

By throwing wipes in the bin, you prevent them from forming large masses that block your plumbing.


5. Food Scraps: Scrape Plates Before Washing

Food particles may seem harmless, but over time, they accumulate and lead to blockages in kitchen sinks. Greasy foods and fibrous vegetables can be particularly troublesome.

  • Prevention Tip: Scrape all food scraps into the bin before rinsing plates, and avoid putting large food particles down the drain.

Using a sink strainer to catch leftover food particles can also reduce the risk of kitchen sink blockages.


6. Soap Scum: Prevent Build-Up with Regular Cleaning

Soap residue, or soap scum, forms when soap mixes with minerals in water. This residue builds up over time, narrowing the pipes and trapping other debris.

  • Prevention Tip: Use a drain strainer to catch soap particles. Consider using soap-free or liquid soap alternatives to reduce soap scum build-up.

Cleaning your drains regularly with hot water and vinegar can also help dissolve soap residue.


7. Dental Floss and Cotton Swabs: Small Items, Big Blockages

Items like dental floss and cotton swabs may seem small, but they can create clogs when combined with other materials in your plumbing.

  • Prevention Tip: Always dispose of dental floss, cotton swabs, and similar items in the bin, rather than flushing them.

Keeping these items out of the drain prevents them from tangling with other debris and causing blockages.


8. Cooking Ingredients: Dispose of Flour, Starches, and Grease in the Bin

Common kitchen ingredients such as flour and starches can swell and clump when mixed with water, forming a sticky substance that clogs pipes.

  • Prevention Tip: Never rinse excess flour, cornstarch, or similar ingredients down the sink. Instead, dispose of them in the bin.

By avoiding the disposal of these ingredients down the drain, you keep your kitchen plumbing clear and clog-free.


9. Foreign Objects in Toilet Drains: Only Flush Toilet Paper

Small objects, such as children’s toys or personal care items, can easily fall into toilets and become lodged in the pipes. These items can cause severe blockages that are difficult to remove.

  • Prevention Tip: Only flush toilet paper. Keep items like sanitary products, cotton balls, and small objects away from the toilet.

Encouraging proper disposal habits in the household can reduce the risk of foreign objects clogging the toilet.


10. Excessive Toilet Paper: Use Moderation to Prevent Blockages

Although toilet paper is designed to break down in water, using too much can cause blockages, particularly in older plumbing systems or homes with low-flow toilets.

  • Prevention Tip: Use toilet paper in moderation and consider flushing more than once if a large amount is required.

Reducing toilet paper use prevents clogs and keeps your toilet functioning smoothly.


Keeping drains clear and preventing blockages is essential for maintaining a functional and healthy plumbing system. Small adjustments to your disposal habits can make a big difference, helping you avoid costly repairs and inconvenience. From disposing of oils properly to using sink strainers, these simple steps keep your drains in excellent condition.
