The Evolution Reverse Osmosis System is a new patented RO technology that fits nicely under the kitchen sink. It is also suited for light commercial applications. The Evolution RO System is built in the USA. The Evolution Reverse Osmosis System is a tankless RO system featuring on-demand, continuous-flow water production. There is no storage tank to fill. The reverse osmosis unit does not run until RO water is needed. This Evolution reverse osmosis unit will provide clean, refreshing, and good tasting water for all drinking, cooking & ice needs. The Evolution patented high-production, low-energy membrane purifies between 700 and 1500 gallons of water per day depending on your water conditions. That is more than 50 times the output of typical home reverse osmosis products. The Evolution provides commercial water production at the price of a residential system. This high capacity performance creates new opportunities for light duty commercial applications. Applications for the Evolution System: Home Use/Light Commercial, Restaurants, Coffee Shops, Juice bars, icemakers, Dentist Office, Aquariums, Grocery Misters. The Evolution high recovery system has consistent TDS rejection and membrane efficiency. The Evolution RO System is engineered for the fewest number of connection points--less chance of leaks. The Evolution system works like a small commercial RO system. It uses two reverse osmosis membrane elements in series to produce the high flow of permeate. The concentrate from reverse osmosis element one is channeled into the inlet at the second RO element. The Evolution stops the flow of water coming in when the system is not in use. An internal shut-off valve will close when the pressure in the permeate line reaches approximately 44% of the system inlet pressure. This function saves water by turning the unit off when permeate water is not being used. The inlet valve will open, and the Evolution will start making permeate water when pressure in the permeate line drops to approximately 11% of the system inlet pressure. 1 cup of product and 3 cups to drain. ALL RO SYSTEMS ARE LIKE THIS, theY NEED TO HAVE THE DRAIN WATER FLUSHING THE SURFACE OF THE MEMBRANE TO KEEP IT CLEAN. The Evolution Tankless RO unit operates on line pressure (60 psi required).

Installation Guide

User Guide


  1. The reverse osmosis system can be installed under or near a sink or any other water supply. The RO assembly can be placed on the sink cabinet floor in any location that does not apply pressure on the disconnect elbows or tubing
  2. A nearby suitable drain point is also required for the drain (waste) water
  3. The RO system can be installed in either a horizontal or vertical orientation. Installation in the basement is also an option
  4. One possible location is near the laundry/utility sink where cold potable water and drain access are close. The location chosen should allow adequate clearance and accessibility for membrane element changes
  5. To provide supply water to the RO system inlet, a garden hose connection fitting is included with the system. Other types of feed supply fittings are available to allow hookup to a variety of feed sources
  6. The feed water valve should be located as close to the manifold assembly as possible
  7. USE A POTABLE COLD WATER SUPPLY ONLY. Softened water is preferred as it will extend the life of the RO membrane elements. Other forms of pre-filtration may be necessary depending on quality of incoming water
