A reverse osmosis, or RO, unit is a pressurized system that installs to your faucet or sink. Water pressure from the tap forces water through a series of membranes that remove organic and inorganic impurities from water. The ideal operating pressure for a RO unit is typically 65 psi (pounds per square inch). The use of a RO pressure gauge is important to monitor ideal operating pressure. If the operating pressure is too low, a RO pump can be installed to increase the pressure.
