How Cooking Oil and Grease Cause Blockages

Cooking oil and grease are common culprits in causing drain blockages. Understanding how these substances interact with drainage systems can help in preventing and managing blockages effectively.

What Happens When Cooking Oil and Grease Enter the Drain?

When cooking oil and grease are poured down the drain, they do not remain in a liquid state. Instead, they begin to cool and solidify as they travel through the pipes. This solidification process leads to the accumulation of grease and oil on the inner walls of the pipes.

How Do Grease and Oil Solidify in Pipes?

Grease and oil solidify in pipes due to the lower temperatures within the drainage system. As these substances cool, they change from a liquid to a semi-solid or solid state. This transformation causes them to adhere to the pipe walls, gradually building up layers that restrict water flow.

What Are Fatbergs and How Do They Form?

Fatbergs are large, solid masses formed from the accumulation of fats, oils, and grease (FOGs) combined with non-biodegradable materials like wet wipes and sanitary products. These masses can grow to significant sizes, causing severe blockages in sewer systems. Fatbergs form when FOGs solidify and bind with other debris, creating a dense, rock-like obstruction.

Why Are Grease Blockages Particularly Problematic?

Grease blockages are particularly problematic because they can lead to complete pipe obstructions, resulting in sewer backups and overflows. These blockages are difficult to remove and often require professional intervention.
