Our Rainwater Harvesting Direct Feed System is designed for the home owner to collect, filter and store rainwater within an underground tank for both domestic and garden irrigation purposes.
In this system, water is fed directly from the submersible pump in the underground tank to each appliance.
Due to the submersible pump featuring pressure sensitivity, whenever a toilet is flushed, the pump will register a drop in pressure, then pump until the cistern is full and automatically switch itself off again
Rainwater is classed as non-potable, allowing water to be used for toilets and washing machines.
Together with garden use with can be more than you’d expect, this equates to around 50% off your incoming mains water.
Should the rainwater tank ever run dry in drought periods, the system is provided with a mains water backup – the Rain Backup in a Box®.
The system uses a level sensor in the tank to open a solenoid valve within the control unit to allow around 200L of mains water to enter the underground tank.
The mains water back up device used in our direct feed system is designed to deliver a small amount of mains water to ensure all domestic appliances are kept fully functioning during times when the underground rainwater tank has insufficient water due to lack of rain fall.
Very importantly the Rain Backup in a Box® is WRAS Approved ( No. 2006006 ). WRAS Approval demonstrates compliance as it is granted directly by representatives of the water suppliers. It is accepted by every water supplier in the UK.
