Descaling of pipes

Descaling is the removal of minerals and rust from the inner surfaces of water, drainage or sewer pipes. Descaling can also remove smaller roots that have grown inside the pipes. It is an important and necessary plumbing procedure in places where the water supply is full of minerals like calcium or magnesium carbonates.

Cast iron pipes tend to have more severe scaling because their inner surfaces become coated with iron oxide as well as calcium and magnesium salts. When a pipe develops a thick, uneven layer of mineral and rust deposits, it begins to snag any solids and grime that flow past the rough sections. Eventually, the pipe becomes clogged or blocked.

Descaling also improves drainage and water flow while increasing the life of the piping system.
