Important Notes -
Flow Control Valves / Restrictors:
Flow restrictors can become clogged over time and should be replaced when installing a new membrane. For this 75 GPD membrane, a compatible flow restrictor typically ranges from 420 mL to 600 mL. Lower flow restrictors are generally suitable for cleaner, low-TDS water, while higher flow restrictors are recommended for higher TDS or more challenging water conditions. *see the related part tab for these options

TFC Membrane Protection:
TFC (Thin-Film Composite) membranes are not chlorine tolerant. A carbon pre-filter is required whenever chlorine is present in the feed water to protect the membrane and maintain performance.
