Description
Whole House Reverse Osmosis Systems
The Ultimate Filtration Experience
The Crystal Quest Whole House Reverse Osmosis System is the highest performing RO System on the market backed by over 30 years of experience. It has been designed and engineered to provide purified water throughout your entire home for many years if properly maintained. Every system is tested in-house before it is shipped and arrives operational, requiring minimal plumbing. As long as the prefilters and membranes are changed regularly, these systems should last from 15-20 years.
All our RO systems are designed to be modular, require little operational maintenance, and be economical. We understand that this is a long-lasting investment for both your family and home, and we aim to make sure you are getting the best possible return on your investment!
Endless Possibilities
It isn't always easy finding a perfect fit, but with 9 different flow rates to choose from, we have a system that will meet your homes' exact needs.

Storage Tank Kit Components
- The RO System - A commercial-grade RO System ranging from 200- 7,000 GPD. Every system is equipped with prefiltration to extend the life of the membranes.
- Water Tank - Water is stored in an atmospheric water storage tank (165, 220, or 500 gallons) that is sized depending on your system, needs and space.
- Pump - As water is used within your home, it will be pumped from the tank as needed.
- Float Switches - Used within your water tank, this regulates when your RO System needs to cut on and off depending on the water level in your tank.
Additional shipping charges may apply for orders with 500-gallon storage tanks

Optional Add-Ons
12 GPM UV Water Sterilizer
For added protection, we offer a premium UV sterilizer to prevent microbiological contamination.
Alkalizing Postfilter Options
With various options to choose from, enhance the alkalinity of your water before it enters your home with the added benefits of a natural Alkalizing, Mineralizing, and Oxidation Whole House filter.
Remineralizer System
In order to provide the best quality of water for our customers, we are offering an optional add-on to our whole house reverse osmosis system. This specially designed unit, based on your Gallons Per Day (GPD) consumption, adds essential minerals back into your purified water and adjusts its pH to prevent any potential damage to plumbing/fixtures and ensure healthier and tastier consumption. The table below gives an overview of our remineralizer system options suitable for different consumption needs and preferences for water alkalinity.
| 300 - 2500 GPD | Single Big Blue Alkalizer/Remineralizer |
| 4000 - 5000 GPD | Remineralizer System (1.5 cubic feet) |
| 7000 GPD | Remineralizer System (2.0 cubic feet) |
(Customers wanting highly alkaline water have the option to use a larger remineralizer system than recommended.)
Pure reverse osmosis water contains no minerals and can sometimes be slightly acidic. Water with a pH below 6.4 is not recommended for human or livestock consumption. The use of a remineralizer as a post treatment will enhance the pH and alkalinity of the water and avoid potential damage to plumbing/fixtures caused by acidic water.
Highly alkaline water may have a taste that us unpleasant to some. This taste can be described as a plastic, metallic, chlorine or fish like taste.
Upgrades:
All systems include a standard with a wide range of features. There are various options and upgrades available to accommodate a diverse range of water treatment applications. Listed below is a selection of the most popular upgrades.
- Stainless-Steel Rotary Vane Pump: Offers a longer lifespan and increase resistance to high TDS feed water and corrosive materials, such as dosing chemical and antiscalants.
- Concentrate recycle valve: Allows for an increase of RO systems efficiency by recycling back wastewater into the feed stream and increasing the system recovery
- SWP Digital Dual TDS Controller: Allow for simultaneous monitoring of both feed TDS and permeate TDS levels, helping to monitor the RO system salt rejection and membrane performance.
- SWP Digital TDS Controller: Allow for monitoring either feed TDS and Permeate TDS levels
- SWP Digital TDS/Conductivity Controller: Allow for the monitoring of the RO permeate water TDS and conductivity levels, useful in evaluating overall system performance IF Computer Controller with feed flush: Allow for pre-treatment lockout functionality, tank level input, features a convenient LED status display indicator for increase ease of use.
- S150 Computer Controller with Feed Flush: Allow for pre-treatment lockout functionality, tank level input, features a convenient LED status display, and alarm function. (only on 4000 gpd and up)
- Chemical Pump Outlet: Provide an integrated power source with the RO system for the connection of a chemical feed pump.
- Blending Valve: Allows for a mixture of feed water into final RO permeate water to achieve desirable permeate TDS.
- Permeate Sample Port: Allows for evaluation of individual membrane performance in on RO system and aids in system troubleshooting and maintenance.
- 240V 50-60Hz or 110V 50-60Hz: Allow for selecting sufficient voltage and hertz use requirement.
- Single Wood Crate
Notes
All systems are rated with 77 Degree Fahrenheit water and TDS (total dissolved solids) under 2000. Please refer to the specifications of the exact system you plan to purchase. If your water falls outside of these constraints, you should contact us for more recommendations.

Parts included
- Reverse osmosis unit, assembled and tested in-house before it ships
- Pre-filter housings with their cartridges: 2 to 4 by size (sediment and SMART Plus on every size, plus a carbon block on 300, 400, 4,000, 5,000 and 7,000 GPD and a GAC stage on 7,000 GPD)
- Thin film composite (TFC) membranes, pre-loaded in the membrane housings: 1 to 4 by size
- High-pressure pump: rotary vane on a 1/2 HP motor (300 to 1,000 GPD) or a 3/4 HP motor (1,500 to 2,500 GPD); horizontal pump on 4,000 to 7,000 GPD
- Pre-filter pressure gauges and a concentrate pressure gauge
- Permeate and concentrate flow meters
- Inlet solenoid valve, concentrate control valve and low pressure switch
- User's manual, the system's test results and a filter housing wrench
- With a storage tank kit: an atmospheric storage tank (165, 220 or 500 gallon), a delivery pump and float switches
Installation Instructions
- Set the system on a level floor and secure it so it cannot vibrate or move; a rubber mat under it helps.
- Before start-up, check that no plumbing or electrical connection came loose in shipping.
- Connect the feed water line to the inlet solenoid valve next to the pre-filter housings, and keep a smooth, steady supply of feed water.
- Connect the purified water line to the storage tank or point of use with no back pressure, using plumbing suited to purified water: RO water runs 1 to 2 pH points lower than the feed and can attack copper pipe.
- Run the concentrate line to a drain with no restriction or back pressure.
- Check that the power supply matches the system and has a protective earth ground. We recommend a licensed electrician wire it to local and national electrical codes.
- With a storage tank kit, install the float switch in the tank and connect it to the system's tank level connections. These are dry contacts: never apply power to them.
- Purge the system with the purified water line sent to drain until no bubbles show in the concentrate flow meter. The settings differ by size, so follow the manual for yours: 500 to 2,500 GPD purge with the power on and the concentrate valve half open; 300, 400 and 4,000 to 7,000 GPD purge with the power off, the concentrate valve fully open, the pump bypass valve closed and the solenoid valve's bypass lever offset.
- On 300, 400 and 4,000 to 7,000 GPD, also flush to drain for about 15 minutes with the concentrate valve fully open, then reopen the pump bypass valve and return the solenoid bypass lever before the power goes on.
- Start the system and set the concentrate valve, and the pump bypass valve where your size has one, for the rated flow and pressure. Never exceed the pressure rating of the membrane housings.
- Check for leaks. After one hour, shut the system down, send the purified water back to the tank or point of use, and turn the system back on.
- Record the readings daily for the first week, then once a week.
