RODI preassure

[tcorrell02]

I just hooked up my rodi this afternoon. Icecap 100 gpd. With no booster pump, I am running between 85-90 psi. Is that too much preassure? Would i benefit from adding a second ro membrane?

Pressure sounds fine. Just confirm you have roughly 3-4x coming out the waste line and your filtered TDS is < (tap_tds * 0.05)
