A blocked toilet is a common household problem that can be caused by several factors. Some of the most common causes of toilet blockages are:

• Flushing inappropriate items: Flushing unsuitable items like sanitary products, baby wipes, and facial tissues can clog your toilet.

• Large amount of toilet paper: Flushing too much toilet paper can cause blockages in your pipes.

• Poor drainage system: If your toilet doesn't drain properly, it can cause water to build-up and result in blockages.

• Foreign objects: Accidentally dropping foreign objects in the toilet, like toys, can also lead to blockages.
