DIRECT OR GRAVITY FED SYSTEM? 

DIRECT SYSTEMS- The collected rain water is supplied from a pump within the tank directly to the pipework in the house. The water is pressurised at each appliance and the tank is topped up automatically in dry spells via a mains water connection in the control panel.

GRAVITY SYSTEMS- The collected rain water is supplied from a pump within the tank which directly supplies a garden tap allowing it to be used in a hose pipe ban. The water is also distributed to a header tank (header tank not supplied) located in the roof space of the property providing gravity fed water to each appliance and the header tank is topped up automatically by mains water in dry spells. This system will continue to operate during a power failure.  


STANDARD OR PRO SPECIFICATION?

The Freerain Pro systems include a higher specification pump, an LED water level indicator to monitor levels from within the house and a holiday protection shut off valve.
