Blocked sinks are a common plumbing problem in Whitrigglees. There are several reasons why a sink can become blocked, such as:

• Food debris: When food particles are washed down the sink, they can accumulate along the pipes in the drain and become difficult to remove, eventually leading to blockages.

• Grease and oil: Grease and oil from cooking can also accumulate in the pipes and cause blockages.

• Hair: Hair strands can easily get stuck in drains, and if not dealt with quickly, they can cause blockages.

• Soap residue: Soap residue can accumulate in pipes, reducing water flow and eventually causing blockages.
