Preventing Blocked Drains: What Shouldn’t You Pour Down Your Drain?

Blocked drains can be annoying, smelly, and inconvenient, not to mention expensive to fix also. If you have recently had a blocked drain, there is no doubt you don’t want to have to deal with that problem again anytime soon. There are many things that people wash down drains or flush down toilets that aren’t obvious drain-blockers. Take a look at the list below to be sure you aren’t disposing of these drain blockers down your drains.

Wet Wipes

Baby wipes or other disposable wet wipes are not designed to be flushed down the toilet, as they cannot dissolve in water like toilet paper does. Dispose of these wipes in the garbage instead.

Feminine Sanitary Products

Pads and tampons are terrible for drains. As they absorb moisture, they can expand and clog drains. These products should be disposed of in the garbage.


Paints should not be poured down drains, as they can harden and block the drain. Paint also poses an environmental hazard as the chemicals in paint will pollute the waterways.

Caustic Soda Or Other Acidic Drain Cleaners

Yes, the product you are using to try to fix your blocked drain may be causing you more damage! If acidic drain cleaners are used incorrectly, they can melt your pipes (if made from plastics). Leave the caustic soda and drain cleaners to a professional plumber.

Produce Stickers

Those little stickers on your fruit from the store may be small, but they still should not be washed down the drain. As they are plastic, they will not biodegrade easily, and they may accumulate (along with other debris) in your drain and cause a blockage.

Oils, Fats And Grease

Cooking fats should not be poured down the drain as they can solidify, causing a blocked drain. Instead, pour your used cooking fats into a jar or other container to dispose of in the garbage, and use paper towel to absorb small amounts of fats before washing.

Coffee Grounds

There is controversy surrounding whether it is safe or not to pour coffee grounds down your drain, but it is best to be cautious. Although coffee grounds are small, they do have the potential to be trapped in solidified fats in your drain and contribute to a blockage. Instead, compost your coffee grounds or dispose in the garbage.

The best way to be sure about keeping your drains clear is to think twice before washing anything down the sink. Using a drain-grate will also help catch bits of food that would otherwise become potential drain -blockers. With a bit of care, you may never have a blocked drain again.
