WHAT CAUSES A BLOCKED DRAIN?
A blocked drain is always inconvenient and has a negative effect on living and working comfort. A blockage can have several causes and is not always your own fault. Soap residues in the bathroom and the washing machine can be a cause. The drain in the sink can become clogged by the accumulation of grease and food residues. The toilet usually gets clogged from flushing things like toilet paper.
