The 3750 Litre Carat Direct Rainwater Harvesting System – Complete Package is designed to go underground and supply water to both home and garden.
Rainwater is collected from the roof of the property and fed into the underground tank via the downpipes. On entry to the tank, the water passes through the filter to prevent any debris from going into the tank. With this system, there is a mains water top-up unit located within the property. This unit supplies mains water to the underground tank when the rainwater level is low. There is a pressure-sensitive pump located in the underground tank, when a valve or tap is opened, water will be pumped under pressure until the valve is closed, allowing the system to repressurise turning the power off to the pump.
Key Benefits
- Simple & quick to install
- Submersible pump supplies harvested rainwater on-demand to WCs, washing machines & external taps
- Mains water back-up unit tops up the water level in the Carat tank when rainwater levels are low, in order to guarantee a continued water supply
- The quiet & conveniently-sized mains water back-up unit will fit in a kitchen or utility cupboard for very low visual impact
- Innovative float sensor detection on the mains water back-up unit ensures that the underground tank is kept supplied with mains water but only the amount necessary to maintain supply to toilets and washing machines. This leaves as much volume as possible in the tank to collect rainwater when available
