Installation and Service Manual – Under-the-Counter Point of Use 5 Stage Reverse Osmosis System
About Your RO Water Treatment System
Thank you for your purchase of the WaterAnywhere home RO reverse osmosis water treatment system. This
drinking water system has been designed for quick and simple installation and maintenance. By carefully
reading this instruction manual and following the operational guidelines you will ensure a successful installation
and reliable operation. Routine maintenance is essential to the longevity and performance of the system.
Filters should be changed every three to six months depending on the quality of the feed water supply.
Notice:
Please read this entire service guide prior to beginning installation.
5 Stages of Water Treatment
Stage1: Sediment Filter Cartridge Replace every 3-6 months
The first filter the water passes through is a five micron filter cartridge. This cartridge removes
sediment including dirt, sand, rust, grit, and other suspended matter from water. This protects the rest
of the filtration stages and equipment from damage and clogging due to buildup of sediment.
Next, the water passes through two stages of carbon filters to remove chlorine and objectionable tastes
and odors from water. These filters also protect the membrane from exposure to chlorine, which would
irreparably damage the membrane.
Stage 4: Reverse Osmosis Membrane Replace every 12 months
The fourth stage is the reverse osmosis membrane, which is the heart of the RO system. The RO
membrane substantially reduces the total dissolved solids (TDS) from the water, including arsenic,
barium, cadmium, chromium (hexavalent), chromium (trivalent), copper, turbidity, fluoride, lead, radium
226/228, and selenium, while washing the rejected contaminants down the drain. The treated water is
directed to the storage tank.
Stage 5: Post Carbon Filter Replace every 3-6 months
The last stage of filtration occurs as the water flows from the storage tank directly before being
dispensed from the faucet. The in-line carbon post filter (also known as polishing filter) removes any
remaining tastes or odors from the water, improving the flavor.
Notice:
Replacement frequency varies based upon incoming water quality and use patterns.
Generally speaking, filters should be changed when there is a loss of performance or
after an extended period of non-use.
System On/Off Valves
Your RO System is equipped with two on/off ball valves. The system feed valve (to be installed into the cold
water supply line) can be used to turn the water to the system on and off for maintenance without disrupting
the water supply to the sink. The tank valve can also be closed to prevent water in the tank from draining out
during maintenance. Both can be opened by turning counterclockwise, and closed by turning clockwise.

*Note that system may operate with higher hardness levels, but the membrane life will be reduced. Use of a
water softener for hard water supplies will increase membrane life and efficiency.
Warnings
Only use this system on potable water supplies. Do not use this system where the
water is microbiologically unsafe or of unknown quality.
Never use hot water or allow the unit to freeze.
Incorrect installation or operation will void the warranty.
Excessive incoming water pressure can cause leaks, flooding and property damage. It
is highly recommended to monitor your home’s incoming water pressure over a period
of 24 hours to determine if a pressure regulator is required.
Manufacturer assumes no responsibility for damages incurred through improper
installation or use of these products.
Ensure that all tubing and fittings used for RO product water are poly material, and not
copper. Due to RO product water being very pure, it can leach the minerals from
copper tubing which will cause a metallic taste in the water or ice and cause the copper
tubing to develop pinhole leaks over time.
