How Your RO Water System Works

HOW YOUR REVERSE OSMOSIS SYSTEM

WORKS

Introduction:

Your Reverse Osmosis (RO) Water

Filtration System uses your household water pressure

to force water through three filters. Minerals and impu-

rities are filtered out. Delicious tasting drinking water

goes to the storage tank-ready for your use. Minerals

and impurities are sent down the drain. The following

paragraphs will explain in detail how your Reverse

Osmosis Water Filtration System works.

Prefilter: 

Water from the cold supply pipe enters the

prefilter. See Fig. 25. The prefilter is a replaceable

sediment cartridge with activated carbon in its compo-

sition. The cartridge reduces taste, odor, sand, silt,

dirt, other sediments, and up to the amount of chlorine

shown in the specifications. 

Reverse Osmosis Cartridge: 

Filtered water flows

from the prefilter to the Reverse Osmosis membrane

cartridge. See Fig. 25. The Reverse Osmosis cartridge

is a tightly wound special membrane. The membrane

reduces the dissolved solids and organic matter. High

quality product water (about one ounce per minute)

exits the Reverse Osmosis cartridge. The product

water flows to the storage tank, postfilter or Reverse

Osmosis faucet. Drain water, with the dissolved solids

and organic matter, is routed to the drain.

Storage Tank: 

The storage tank holds product water.

See Fig. 25. A diaphragm inside the tank holds water

pressurized to about half of supply water pressure

when the tank is full. This provides fast flow to the

Reverse Osmosis faucet. When the tank is empty of

water, the pressure at the air valve is  5 - 7 psi.

Postfilter:

Water goes through the postfilter before

going to the Reverse Osmosis faucet. See Fig. 25.

The postfilter is an activated carbon type filter. Any

remaining tastes and odors are reduced from the

product water. Clean, high quality drinking water is

available at the faucet.

Reverse Osmosis Faucet: 

The sink or countertop

faucet has a hand operated knob to dispense drinking

water. See Fig. 25. An air-gap is built into the faucet

drain water connection to comply with plumbing

codes.

Faucet Electronics: 

Inside the faucet base is a bat-

tery operated 6 month timer. See Fig. 15.
An amber LED indicator is located in the front of the

faucet base. This LED will flash continuously after 

6 months have passed. This indicates that it is time to

replace the battery, prefilter and postfilter.

Shutoff Assembly: 

The unit has an automatic shutoff

system to conserve water. When the storage tank has

filled to capacity, and the drinking water faucet is

closed, pressure closes the shutoff to stop flow to the

drain. After enough drinking water is used, pressure in

the system drops, and the shutoff opens to allow the

tank to be refilled. See Fig. 25.

Check Valve: 

A check valve is located in the Reverse

Osmosis manifold above the center cartridge. The

check valve prevents a backward flow of product

water from the storage tank to drain. A backward flow

could damage the Reverse Osmosis Membrane. 

See Fig. 25.

Flow Control: 

Water flow to the drain is restricted by

the flow control. It maintains the desired flow rate to

obtain the highest quality drinking water. The flow con-

trol is located inside the elbow fitting on the Reverse

Osmosis manifold drain port. See Fig. 25.
