The Hazards of Pouring Flour Down Drains Flour, a common kitchen staple, can cause severe plumbing problems when poured down the drain. When mixed with water, it forms a sticky, glue-like paste that adheres to pipes.

This paste traps other debris, creating clogs over time. Combined with grease or waste, it forms dense blockages that are hard to clear, leading to slow drains or complete obstructions.

Even small amounts of flour can accumulate, increasing the risk of clogs. Proper disposal of flour is a simple way to avoid plumbing issues.
