Common questions
What does a flow restrictor do?
It controls how much reject water leaves the membrane. Too little flow and the membrane scales up; too much and you waste water and lose pressure.
Which FR number do I need?
Match it to the membrane: roughly 300 for 50–75 GPD, 450 for 80–100 GPD. Send us your membrane model and we will confirm.
