Friendly Reminder

It is never a bad idea to change your Check Valve and Flow Restrictor when you change your membrane, in fact, Without a properly working check valve, the unit will not shut off properly when the tank is full, a great deal of water will be wasted, and eventually the membrane will be ruined. a few dollars spent can extend the life of your system, filters, membrane and save water dramatically.

Flow Restrictors (also known as Flow Controls or Capillaries) are required for all reverse osmosis systems. The Flow Restrictor must be properly sized to the RO membrane capacity. Flow Restrictors create pressure throughout the reverse osmosis membrane element and maintain a desired ratio of reject flow (to drain) and permeate (product) flow.
