A blocked toilet is a common plumbing problem that arises when water and waste cannot pass through the pipes freely. The blockage can happen anywhere along the drainage system, from the toilet bowl to the sewage pipes outside. Some of the most common causes of blocked toilets include:

• Flushed objects: This is one of the leading causes of blocked toilets, especially if the objects are non-biodegradable. Examples include sanitary products, cotton balls, wipes, and toys.
• Build-up of toilet paper: Excessive use of toilet paper can clog the pipes and cause a blockage over time.
• Foreign objects: Items such as jewelry, keys, and mobile phones can accidentally fall into the toilet and cause a blockage.
• Damaged pipes: Old and worn-out pipes can collapse or crack, causing blockages.
