RO systems & flow restrictors

[banditpowdercoat]

Pressure and cold really affect the speed of RO water. Im running approx 70psi here at my house, and with cold water, I get 40gpd or so. It's a 50GPD membrane and restrictor. Most RO systems are rated at 72*F water and 65-70PSI I think. Higher water temps really increase the filtered water output of my system. It's a Kent RO/DI unit I have, but they are all pretty much the same.
