pipe network, the use of a filter and a backflow preventer is recommended and sometimes required by
law (according to DIN1988).

is fully assembled and ready includes:
- a water filter to ensure the water quality,
- a water meter to the monitoring of the targeted consumption
-a back flow prevention valve is a requirement of many waterworks
- Two shut-off valves for easy maintenance
