GRANDER® Water Revitalisation Devices for Apartments and Flats

For installation on shut-off valves (in apartments or flats)

The top of the existing isolation valve can easily be replaced by the VAS valve adapter fitting (as per DIN 3512).  This makes it possible to quickly install the GRANDER® water revitaliser into existing supply pipes without cutting or prying open the pipe of the apartment or flat.  These GRANDER® Apartment Revitaliser Units are also available for screwable ISTA water meters.
