What commonly causes blockage in home plumbing systems?

Oils, greases, and fats are commonly known to cause blockages in home plumbing systems. When these substances are discarded down the drain, they can solidify and build up on the interior walls of pipes over time. This accumulation narrows the passage through which water can flow, leading to clogs. The combined effect of these materials can create a sticky residue that attracts other debris, further exacerbating the blockage.

In contrast, while soap and detergent can contribute to buildup, they generally dissolve in water and are less likely to create a significant obstruction compared to oils and greases. Sand and dirt can enter plumbing systems, particularly from outdoor sources, but they usually settle out and may not cause as severe clogs compared to the viscous nature of fats. Hair and lint can also create blockages, but they tend to be less problematic than the accumulation of greasy substances, which can create a more substantial blockade in the plumbing. The sticky nature of oils, greases, and fats makes them a common and serious threat to maintaining clear home drainage systems.
