Flow restrictors are crucial to a properly functioning RO system. Be sure to have the appropriate flow restrictor for the membrane you have. If you decide to change your membrane to a higher or lower GPD membrane, you must also replace the flow restrictor to correspond with the membrane.
- Flow Restrictor 500ml/min is for a 50 GPD Membrane.
- Flow Restrictor 800ml/min is for a 100 GPD Membrane.
