RainRetain Home System
This ingenious system uses cutting-edge pump technology to run alongside the mains water supply into your house, switching automatically as required between stored rainwater and mains water. Thanks to a very efficient, self-cleaning filter it has a water yield of more than 95%.
When the holding tank is running dry, there is a small automatic charge of mains water into a separate storage tank. This ensures that the system will never run dry, but also that there is no mains water used unnecessarily once the main tank is filled with rainwater again.
RainRetain Home System includes:
Dry, wall-mounted pump control unit with automatic mains switch
Pump delivers rainwater to appliances at mains pressure
Equal wall thickness throughout the tank makes it stable, strong and reliable
Tank is made from Duralen, a recyclable material
Lightweight tank can be supplied in two halves for restricted sites
Wall duct DN100
Floating water extraction unit
PE suction pipe 12m
