Compact unit for automatic management of rainwater recovered in homes.

Designed for plug & play use, it consists of a 15-litre accumulation tank with levelling system, pressurisation equipment based on a Tecnopres 15 4M electric pump, expansion vessel, automatic 3-way valve and 3/8" BSP intake for mains water, 1” suction for the rainwater tank and 1” discharge. 

The management system built into the pump connection box allows reliable management of the water supply at a constant pressure to all connected points of the home. 

It is correctly designed to meet all standards, particularly EN 1717 and EN 13077, including the corresponding overflow system. This compact unit for household applications guarantees the water supply in the home, giving priority to the rainwater network or, alternatively, supplying mains water if the rainwater runs out.
