Hi everyone,

How do the backflush valves work? Do the membranes work with some backpressure, and the backflush valves release the pressure, so they're able to flush the membranes? I am trying to redo my old school Air Water Ice Typhoon and add a BRS water saver to it, but I cannot for the life of me figure out how the backflush is supposed to work. The original that came with it had another output with a check valve on it, but if you watch BRS's video on the subject, they just replace the flow restrictor with one that has a valve on it (which is what I have). There is not much info on this out there... and I'm not quite sure what to do here to set this thing back up.

I think the flush valve bypasses the flow restriction on the wastewater.
This creates more flow across the membrane surface to wash away any/some of the build up on the membrane.
Some one will correct me if I'm wrong.
