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.
Stage 2 & 3: Carbon Block Filter Cartridges
Replace every 3-6 months
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: (2) Reverse Osmosis Membranes
Replace every 12 months
The fourth stage is the reverse osmosis membrane, which is the heart of the RO system. To achieve a
higher product water flow, the water stream is split in between two RO membranes, working in parallel.
The RO membranes substantially reduce 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.
