Clogged toilet? Causes, consequences, and solutions
A clogged toilet can cause an unpleasant odor, flooding, and ultimately water damage to walls or floors. Common causes include non-biodegradable products like wet wipes and sanitary towels, as well as grease and limescale. In older homes, sewer subsidence can lead to structural problems. Accumulation of paper or plastic items also frequently causes blockages.
- Sanitary facilities not used correctly: Wet wipes, tampons, paper towels and toys often end up in the toilet and quickly cause a clogged drain.
- Regular limescale: In regions with hard water, pipe walls can become clogged with limescale, especially in older sewer pipes.
- Structural subsidence: Older homes sometimes suffer from sagging or cracked sewers, which cause solids to remain trapped.
- Fat deposits: When fats are thrown into the toilet bowl, they harden in the pipes and block the flow.
Our toilet unblocking service not only identifies and resolves the immediate blockage, but also offers advice on preventing future blockages. We'll contact you immediately for a solution within 24 hours and provide clear, personalized advice.
