Blocked sinks are a common problem in homes and businesses. It's often caused by the buildup of food, hair, and other debris in the plughole or drain. Over time, this can lead to a complete blockage, preventing water from draining away and causing water to flow back up the sink, creating unpleasant smells and potential health hazards.

Ignoring a blocked sink can lead to even bigger problems, such as damage to pipes and fixtures, water leaks, and mold growth. It's important to address the issue as soon as possible to avoid these costly and inconvenient outcomes.
