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® Apartment Units into existing supply pipes without cutting or prying open the pipe of the apartment or flat. These GRANDER® Apartment Units are also available for screwable ISTA water meters.
