Saponification

Saponification is a chemical process in which a fatty acid is neutralized, forming soap and glycerin. In plumbing, saponification can occur when fats, oils, or grease (FOG) in wastewater react with alkaline substances, leading to the formation of soap-like deposits within pipes. These deposits can cause blockages, reduce flow, and lead to sewer line backups. To prevent saponification, regular cleaning of pipes, grease traps, and drain lines is necessary, especially in commercial kitchens or food processing facilities where FOG levels are high.
