Although many people assume that toilet paper is the main cause of blocked drains, there are actually a variety of different culprits.
Hair, food, grease, and soap scum can all build up over time and reduce the diameter of your drain pipe, eventually leading to a complete blockage. Toilet paper, on the other hand, is designed to break down quickly in water. In fact, it dissolves far faster than most other types of paper products.
As a result, toilet paper is unlikely to cause a drain blockage on its own. However, if it is combined with other items, it can contribute to a clog. If you are concerned about your drain becoming blocked, you can always contact a professional plumber for assistance.
