Operating pressure range: 20 psi - 85 psi

Maximum allowable hardness level: 10 gpg
Maximum allowable TDS (total dissolved Solids) level: 1800 ppm

The Kwik-Change™ Reverse Osmosis System allows you to change your filters without turning the water supply to the system off. A simple 1/4 turn movement disconnects and connects the cartridges from the housing, without water leaks or spills, making this the fastest changeable cartridge system on the market. However, placing a towel under the RO module might be a good idea just in case any excess water left in the cartridges drips out during the changeover. To help make the removal of the cartridges even easier, the heads and housings can be lifted by up to as much as 90° from their normal vertical position.

The entire system easily installs under the sink using the Adapt-A-Valve™ to connect to your water source for 3/8" compression or 1/2" NPT and includes a 3 gallon water storage tank. A stylish chrome designer air gap faucet is included with the Kwik-Change™ Reverse Osmosis System for easy mounting to the sink or countertop.

These reverse osmosis membranes have a life expectancy between 2 and 5 years. Membrane longevity depends on your water conditions and the amount the RO system is used. Your water hardness should not exceed 10 grains per gallon or 170 ppm for optimum membrane life. This system will operate with water hardness levels over 10 grains per gallon, but the membrane life will be shortened. The reverse osmosis membrane is essential and critical for the effective reduction of total dissolved solids (TDS). We recommend testing your reverse osmosis water periodically to verify your system is working properly. Watts^® recommends replacing the membrane when total dissolved solid reductions fall below 75%.

This system is considered a 4-Stage RO because treatment is done in stages within the complete system. The first stage is a 5 micron water filter to remove dirt and rust particles that can affect the taste and appearance of water. The second stage is a 5 micron carbon block filter to reduce chlorine and other liquid substances that can cause bad taste or odors. The third stage is the reverse osmosis (RO) membrane and the heart of this system. The reverse osmosis membrane is semi-permeable to effectively remove or reduce sodium and other dissolved solids as well as heavy metals such as copper, lead, and arsenic. It will also reduce cysts such as Giardia and Cryptosporidium. The fourth and final stage is a granular activated carbon filter used after the storage tank as a polishing filter to ensure unpleasant tastes or odors are not present. Since the process of making high quality drinking water takes time, this reverse osmosis system is equipped with a 3 gallon storage tank.

Kwik-Change™ Reverse Osmosis can help reduce the following contaminants:

Arsenic Barium Cadmium Chromium (Hexavalent) Chromium (Trivalent) Copper	Cysts Cryptosporidium Entamoeba Floride Giardia Lead Nitrate	Nitrite Perchlorate Radium 226/228 TDS (Total Dissolved Solids) Turbidity Toxoplasma
Please note: The above list of contaminants reduced by this water treatment system are not necessarily in your water. Only a test of your water can determine if any are present.

Frequently Asked Questions

Q. "Can I use copper tubing to connect my Reverse Osmosis system to my dispenser faucet?"
A. You can run copper tubing to supply water to the Reverse Osmosis system but Reverse Osmosis water should NOT be run through copper tubing or any metal piping. Reverse Osmosis water is so pure it will cause the copper to leach into the water causing an objectionable taste to the user and after a short time pin holes will form in the copper tubing as it erodes.

Q. "Our water hardness is over 10 grains per gallon, and you say the membrane life may be shortened. How much will it be shortened?"
A. Every water supply has different conditions and there is no way to know how much shorter the life expectancy of the membrane will be. However, the addition of a water softener can help lengthen the membrane life since a water softener will usually reduce hardness down to 1 grain per gallon or less.

Q. "How long does it take to fill the water storage tank?"
A. Normally it takes 4-6 hours to fill the storage tank. If you have low incoming water pressure or water temperature then the production rate can be drastically reduced.

Q. "We are installing our Reverse Osmosis system. How much air pressure should be in the provided storage tank?"
A. The storage tank air pressure should be between 5-7 psi when empty of water. If the tank air pressure is below 5 psi then add air. If the tank air pressure is above 7 psi then bleed the air until it is below 7 psi but not lower than 5 psi. Check the air pressure of the storage tank only when the tank is empty of water.

Q. "We had our water tested and test results show our hardness level is 230 ppm or 230 mg/l. How do we convert this number to grains per gallon?"
A. To convert from parts per million (ppm) or milligrams per liter (mg/L) to grains per gallon (gpg), divide the ppm or mg/L number by 17.1. Example: 230 ppm ÷ 17.1 = 13.45 grains per gallon.
Note: One part per million (ppm) is equal to one milligram per liter (mg/L).
