Rainwell RFD
Operation
The Rainwell RFD's innovative rainwater filtration and diversion system has no moving parts and requires minimal maintenance.
Roof rainwater enters the RFD and passes through a self-cleaning filter (1) to a diversion chamber (2), which directs the flow to the tank (3) via the connection pipe (4).
When the water level in the tank reaches the overflow outlet (5), the incoming rainwater fills up into the diversion chamber to divert the flow through an opening (6) and back into the downpipe.
The RFD's filter design uses the rainwater's downward force to push debris across the filter surface and out the filter opening. When wet, some debris will fix to the filter, but will easily fall off when dry.
A hinged cover allows access to the filter for inspection and occasional cleaning. The frequency for cleaning will depend on the amount and type of debris falling on the roof.
Regularly cleaning gutters will prevent debris build-up which can create sludge, breed mosquitoes and reduce the life of guttering.
