Exterior drains that collect surface water (yard drains, driveway trench drains) inevitably carry fine particles of dirt, sand, and gravel. Unlike organic matter, sediment does not dissolve. It settles in low spots and compacts into a hard, abrasive sludge.

Leaves, grass clippings, pine needles, and twigs wash into drains. While they will eventually decompose, the process takes months. In the meantime, they mat together, creating a fibrous plug. This is particularly common in gutter downspouts connected to underground drainage. drain cleaner outside

This scale builds up on the pipe walls, eventually narrowing the diameter to a pinhole.
