Clogged drains are a regular source of frustration for homeowners, but did you know that some of the most unexpected objects may cause tenacious blockages? Understanding these surprise culprits is critical for keeping your plumbing system in good working order and avoiding costly repairs. Now we will look at five surprising reasons of clogged drains that every homeowner should be aware of.

Soap Scum Buildup

While soap is intended to keep things clean, it can eventually lead to clogged drains. When soap and minerals interact in hard water, they produce a sticky deposit known as soap scum. This scum can build up within pipes, trapping additional debris and slowly reducing water flow. Regular drain cleaning may assist avoid soap scum accumulation and maintain your plumbing system in good working order.

Dental Floss

Dental floss is another unintentional factor behind clogged drains. Although it appears to be innocuous, dental floss is engineered to be strong and resilient, which allows it to tangle with other items in your pipes and cause clogs. To avoid plumbing problems, throw away dental floss rather than flushing it down the drain.

5 Surprising Causes of Clogged Drains You Need to Know

Cooking Grease and Oil

Many people are guilty of throwing cooking grease and oil down the drain, ignorant of the damage it may cause to their plumbing system. While these chemicals are liquids when heated, they harden as they cool, covering the walls of pipes and limiting the channel for water flow. Over time, this accumulation can cause serious obstructions and even pipe damage. Instead of throwing oil down the drain, collect it in a container and discard it once solidified.

Flushable Wipes

Flushable wipes, despite their name, are not as flushable as one might expect. Unlike toilet paper, which dissolves fast in water, flushable wipes are constructed of long-lasting polymers that can withstand moisture. As a result, they can accumulate in your plumbing system and cause clogs. To avoid blockages, dispose of flushable wipes in the trash rather than flushing them down the toilet.


Hair is one of the leading causes of drain blockages, although many people underestimate its importance. Hair from washing, shaving, or grooming may readily build in drains, forming tangled masses that block water flow. Using a drain cover or hair-catching device can assist trap hair before it reaches the drain, lowering the likelihood of clogging.

To Summarize

Every homeowner dreads clogged drains, but recognizing the surprising causes might help you take proactive efforts to avoid obstructions.
