Apparatus for preparing aqueous salt solution

摘要

An installation for preparing an aqueous salt solution for reducing the hardness of water, supplied to an electric household machine, comprises a by-pass duct which is equipped for selective constriction and can connect an entry pipe (16) directly with a discharge line (20). The apparatus features a second partial by-pass duct, having a short passage inside a salt container (10), which can be constricted selectively and can connect the entry pipe with the discharge pipe.
