The Hazards of Pouring Flour Down Drains

When flour mixes with water it forms a paste that behaves like glue. This coating clings to pipe walls, traps crumbs and lint, and eventually creates a thick obstruction.

Combined with cooled cooking oil the mixture hardens into a dense mass that normal flow cannot dislodge. Even small repeated wash offs accumulate. Wipe bowls and utensils with a dry towel before washing to keep flour out of plumbing.
