What does incrustation in a water system typically result from?

Incrustation in a water system primarily results from corrosion or rust. This process occurs when minerals and other substances from the water settle and accumulate on the surfaces of pipes and fittings over time. As pipes corrode, they may release metal oxides, which can combine with minerals already present in the water, leading to the buildup of a hard outer layer or crust. This incrustation can impede water flow and reduce the efficiency of the system, making it crucial to address rust and corrosion to maintain an effective water distribution system.

While factors like water temperature changes, high flow rates, and poor water quality can influence the overall condition of a water system, they are not the primary causes of incrustation. Water temperature changes may affect solubility and precipitation of minerals, and high flow rates might help prevent incrustation by reducing the time that minerals have to deposit. Poor water quality can lead to a variety of issues, but the specific mechanism of incrustation is most directly linked to the processes of corrosion and rust.
