Overview
Mechanical disconnectors of this type are suitable for the protection of drinking water systems as required by EN 1717 "The technical regulation of drinking water systems" and correspond to DIN1988 part 4 type 1 construction.Their purpose is to protect systems against back pressure, back flow and back syphonage of non-potable water into the public water supply network.Mechanical disconnectors can be used to provide protection up to and including liquid category 3 (slightly toxic substances) and therefore offer better protection than check valves.
