What Is A Water Softener?
A Water Softener is a filter cartridge or system that works to remove high concentrations of calcium and magnesium that cause hard water. When water flows through a Water Softener, the system filters out these hard water minerals, and the softened water then leaves the water softening system to flow through plumbing.
In espresso machines, water softeners reduce the calcium or magnesium ion concentration in hard water. Calcium and magnesium carbonates tend to precipitate out as adherent solids on the surfaces of pipes and especially on espresso machine heat exchanger surfaces of boilers. The resulting scale buildup can restrict water flow.
