Connection set for GRM

DetailsThe GRM 2.0 Rainwater Manager supplies all consumers with water fully automatically. If there is no rainwater in the underground tank (e.g., due to a prolonged dry spell), the pump is automatically supplied with potable water via the replenishment tank without any detours. Once the underground tank refills, the system automatically switches back to rainwater supply. The pump (Amiga MH800 4M cast iron/stainless steel) is equipped with dry-run protection. The free outlet in accordance with DIN EN 1717 prevents rainwater from mixing with water from the water utility.

The free outlet in accordance with DIN EN 1717 prevents rainwater from mixing with water from the water utility.
