If you have enough water pressure to make RO water you have enough to flush

Steve, when the valve is open and it bypasses the flow restrictor for flushing there is only 30 psi through the unit. I have a friend that is a pro ro guy and he told me that isn't enough psi to flush the membrane well enough to make a difference. He said flush kits really only work on high psi commercial systems. Maybe that's not true...I don't know.
I think you're right about the membrane. I flush my membrane a few times mid-use too, and always make sure that my storage barrel is almost empty so I make 50 gallons at a time since the membrane will last longer than frequent, short uses.
