Hydrologic EvolutionRO 1000 High-Flow Reverse Osmosis System

Achieve the highest flow rates from THE MOST EFFICIENT RO SYSTEM ON THE PLANET! 

The EvolutionRO1000 is a reverse osmosis water filter unit. It uses water pressure to reverse a natural physical process called osmosis. Water, under pressure, is forced through semi-permeable membrane to filter out minerals and impurities. Treated drinking water goes through the blue line. Minerals and impurities are sent to the drain with RO waste water though the black line.

The system includes a replaceable carbon pre-filter and 2 membrane elements.The pre-filter reduces sand, silt, dirt, rust particles, other sediments, chlorine, chloramines, iron and sulfur from the incoming water supply before they enter the RO membrane elements.

An optional high capacity pre-filter, the Pre-Evolution, is available to add 2 extra stages of pre-filtration. This will help further reduce the contaminants listed above as well as cut down on filter changes and maintenance of the EvolutionRO1000. An optional De-Ionization post-filter will remove any remaining PPM of TDS in the water after passing through the RO system. evolution-RO1000

Reverse osmosis (RO) is a separation process that uses water pressure to force a solvent through a membrane that retains a solute on one side and allows pure water solvent on the other side. More formally, it is the process of forcing a solvent from a region of high solute concentration through a membrane to a region of low solute concentration by applying a pressure in excess of the osmotic pressure. This is the reverse of the normal osmosis process, which is the normal osmosis process, which is the natural movement of solvent from an area of low solute concentration, through a membrane, to an area of high solute concentration when no external pressure is applied.

The membrane here is semipermeable, meaning it allows the passage of solvent but not of solute.

EvolutionRO 1000 Installation and Maintenance Manual

Installation Instructions

STEP 1: Install cold water supply fitting. Use either the included garden hose connector or any of the other optional feed fittings
STEP 2: Install optional drain adapter
STEP 3: Make tubing connections
STEP 4: Install RO assembly (see Quick Start Guie for pictures)
STEP 5: Begin running water through the system

NOTE: Consult a licensed plumber if you are not familiar with plumbing procedures

Step 1: Install Cold Water Supply Fitting

A female garden hose adapter is included to hook up to a garden hose or hose bib (spigot). Keep the length of garden hose as short as possible to minimize pressure loss. A variety of other feed fittingsand feed valves are available to connect to other existing plumb-ing. Check with your dealer or contact Hydro-Logic. Comply with local plumbing codes.


NOTE: Be sure to turn off the water supply before installation

Cold water pipes vary in size and style.  The installer will determine the type of valve that will be used.  Install a valve on the cold water supply pipe to adapt 1/2-inch OD tubing.  If threaded fittingsare used, be sure to use pipe joint compound or Teflontape on outside threads.

Step 2: Direct black drain line to an appropriate drain location or install optional drain adapter

The optional 3/8” quick connect drain saddle adapter must be installed on the main sink drain above the P-trap. The drain adapter is designed to fit1” to 1½”sink drain pipe. The black drain line may also be directed into a drain point or outside. The drain water can be re-used for a variety of applications including watering your landscape plants, trees, shrubs and lawns. The drain (waste) water contains the majority of the contaminants in your source (tap) water. The PPM of the drain water are typically 33% – 55% higher than the source water. A certain amount of drain water is necessary to flushthe contaminants away from the membranes and prevent them from fouling or scaling prematurely. DO NOT restrict the black drain line, let it flowfreely. The Evolution comes with a green elbow fittingthat produces a waste water to usable product water ratio of 2:1, based on inlet pressure of 60-65 psi. Lower pressure will yield a higher waste to usable product water ratio. An optional 1:1 ratio orange elbow fittingis included. Using this elbow may decrease the life expectancy of your Evolution membranes depend-ing on the PPM of source water.

Step 3: Make Tubing Connections

The connections to the faucet or water source should be complete, the remaining connections are:

•  Feed connection—white 1/2” tubing from feed fitting or feed valve to pressure gauge and then to white elbow connector

• Drain connection—black 3/8” tubing from green elbow connection will attach to the optional drain adapter or be directed to appropriate drain location

• Purified water connection—blue 3/8” tubing blue elbow connection to reservoir or tank via optional 3/8” float valve

• Install the fittings to the manifold

A typical connection is shown in Figure 1:  ‘Side View and Cutaway of Tubing Fitting

NOTE: For optimal system performance, we recommend using tubing lengths that are as short as possible.

Feed Pressure Gauge w/ “T” fitting

The supplied pressure gauge should be connected to the feed line to monitor system feed pressure. For proper system performance, the inlet feed pressure must be between 40  and 80 psi when the system is in operation. Insert the short length of tubing into the white elbow connector. Then install pressure gauge w/ “T” fitting.Then install long length of white tubing to other end of pressure gauge “T” fitting.

Inline Shut-off Valve

The supplied 3/8″ inline shut-off valve is designed to be installed on the blue pure water line. The system can be shut-off by using this valve.

Step 4: Install RO Assembly

The RO Assembly includes the following components: filter housings (3), support leg, carbon pre-filter, and RO membrane elements (2). The tubing is attached to the manifold by the elbow connectors. When choosing a location for the system, allow enough tubing for it to be moved for periodic servicing of the pre- filter and membrane elements: Figure 2: ’RO Assembly.’



Do not attempt to mount/hang the system unless you have the Evolution mounting bracket by Hydro-Logic (HL# 10057). Do not try to drill mounting holes anywhere on the system.

Recommended Placement Positions

The RO assembly should be positioned in one of two ways. The first position is with the unit standing upright using the support leg with the filter housings horizontal. The tubing is directed to provide the best fit.

The second position, sets the unit on end so the filter housings are pointing up. The tubing is directed upward and the locking bar is down to lock the tubing connections. See Figure 3:  ‘System Positions.’
NOTE: Ensure that the support leg is installed on the filter housings.

Connection Lubrication

Connections with O-rings must be properly lubricated. The following instructions describe the method and locations for lubrication.

Six packets of silicone lube are supplied. One packet should be completely used to lubricate the O-ring contact surfaces in the 3 manifold ports and two RO membrane locations (Figure 4). Follow Figure 5 and lubricate the filter seat and the flat surface below the threads for the 3 sump locations. Use a complete packet of silicone for each sump location.

NOTE: To properly lubricate the O-ring contact area, a film of clean silicone grease is applied. The film should cover all of the surface area that the O-ring will slide over and seal with. Do not use grease containing petroleum products.

NOTE: The Quick Start guide indicates applying the lube directly to the O-rings as opposed to the con-tact surfaces of the O-rings. Either method is appropriate.

NOTE: Please save extra lube packs for future membrane changes. Extra lube packs can be sourced through Hydro-Logic.


The table below shows the coding system for the fitting connections.  Each fitting has a unique “keyed” socket on the manifold. Each fitting also has a graphic symbol molded into the elbow with a corresponding symbol on the manifold.



Do not turn the incoming water valve on until the locking bar is in place.When all of the connections have been made, use the locking bar to hold the fittings in position. Match the symbols on the locking bar to the corresponding symbols on the manifold.


Step 6:  System Startup

1. Inspect all connections.

2. Position manifold horizontally with openings facing up.

3. Remove new membrane elements from plastic packaging. The blue and green tape surrounding the membrane are an important part of the membrane element and should not be removed.


Elements contain a food grade preservative. The use of sterile/latex gloves is recommended.

4. Lubricate all O-ring seats in the manifold that come in contact with the sump and element O-rings. Refer to “Connection Lubrication.”

NOTE: To properly lubricate the O-ring contact area, a film of clean silicone grease is applied. The film should cover all of the surface area that the O-ring will slide over and seal with. Do not use grease containing petroleum products.

5. Securely insert O-ring end of membrane elements into manifold. Push the membrane straight down into the hole in the manifold. Do not twist or rock the membrane when installing, as this may damage the o-rings.

6. Remove pre-filter from packaging. Check that gaskets are in place.

7. Place pre-filter in manifold

8. Install filter housings and tighten until they bottom out. (DO NOT OVERTIGHTEN). You can use the support leg as a housing wrench.

Pressure Test System

To check for leaks, the system must be filled with water and brought up to operating pressure.

1. Open cold water feed valve slowly. Run at 1/2 open for a minute, then open fully.

2. Make sure included shut off valve installed on the blue purified water line is in the closed position

3. Check for leaks.

NOTE: When the system is initially turned on, water may temporarily sputter until all the air is purged. Allow 1 to 3 hours for any noise from trapped air  in the system to subside.

4. Purge the system. Run the water through the RO system allowing ALL water to go down the drain for two to eight hours to stabilize the pH and PPM’s of the purified water.

NOTE: A minimum of a 2 hour flush is required to remove the food grade preservative. After 8 hours performance will reach its stable maximum performance.
