Over years, these minerals precipitate out of the water, forming a hard, concrete-like scale known as calcium carbonate or calcium sulfate . This scale builds up on the pipe walls, eventually narrowing the diameter to a pinhole.

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. In many regions with hard water, the most
