Distribution fitting for water treatment systems

Abstract

Distributor fitting (16, 18) for water treatment arrangements (12, 14, 124, 126), comprising (a) a fitting body (20) connectable to a container (22) for water treatment; (b) a distributor chamber (36) provided in the fitting body (20); (c) several channels (28, 30, 32, 34, 80, 82) connected to the distributor chamber (36), one channel being a raw water inlet (32) and one channel being an outlet (34) for treated water; (d) a piston (68) movably guided in the distributor chamber (36) between an operating position and a maintenance position, which in the operating position opens a connection from the distributor chamber (36) to the raw water inlet (32) and a connection from the distributor chamber (36) to the outlet (34); characterized in that the piston (68) in the maintenance position closes both the connection to the raw water inlet (32) and the connection to the outlet (34) simultaneously.
