Our Rainwater Harvesting Gravity 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.
Our innovative low energy rainwater harvesting system, specified to nearly all customers when a small header tank can be situated in a loft space.
The system works by pumping from the underground tank, through a control unit, into a Smart Header Tank within the loft space. Water is then gravity fed to toilets and washing machines.
The Rain Director® has huge benefits over traditional systems. Most systems start and stop the pump every time the toilet is flushed, meaning the pump cycles 15-20 times per day.
The Rain Director® uses 6-8 times less energy than a traditional system by completely filling the Smart Header Tank, then not using the pump again until the Smart Header Tank is nearly empty. This reduces pump cycles to around 1-2 per day, and therefore greatly reduces energy consumption and pump ware.
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.
It is important to remember that you should always plumb the outside tap or taps directly from the pump so you get full pump pressure , do not feed them from the header tank.
Should rainwater ever run low in the underground tank, the system automatically registers and delivers mains water directly to the Smart Header Tank.
This means your toilets will work in every eventuality- low rainwater, pump failure or even power cut. The system also features intelligence such as a “Mains Water Mode” to divert the home onto mains water, so rainwater can be conserved for the garden if hosepipe bans are being introduced.
Unlike any other gravity feed system, the Rain Director® also features a “Holiday Mode” recycling the water in the loft space every 3 days to prevent stagnation if the system is not used.
Very importantly the Rain Backup in a Box® is WRAS Approved ( No. 2010039 ). 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.
