Bring reverse osmosis treatment into your whole-house water plan with a system sized for your household. The Crystal Quest Whole House Reverse Osmosis System combines pre-filtration and RO membranes in a modular design, with rated production options from 300 to 7,000 gallons per day. Choose a standalone unit or add a storage tank kit to build a setup around your water analysis, daily demand, and available space.
Why Customers Choose This Product
Product Highlights
RO Treatment with Pre-Filtration
The system uses reverse osmosis membranes to reduce dissolved solids, with pre-filtration ahead of the membranes. Treatment results depend on feed-water quality, operating conditions, and maintenance.
Size Around Daily Demand
Select a rated production capacity from 300 to 7,000 GPD. GPD describes daily water production, not the instantaneous flow delivered at your fixtures; have an installer size storage and delivery equipment separately.
Optional Storage Tank Kits
Storage kit configurations add an atmospheric tank, a delivery pump, and float switches that control RO operation according to tank water level. Select 165, 220, or 500 gallons, and confirm compatibility and installation space before ordering.
Pump Choices
The listed pump selections are brass rotary, stainless steel rotary, and a 1.5 HP horizontal pump. Confirm the appropriate choice for your selected capacity and feed-water conditions.
Plan Any Additional Treatment
Optional UV treatment, remineralization, monitoring controls, and other upgrades are described for this system range. These are not included unless expressly specified in your order; confirm compatibility and availability before purchase.

Ideal For
- Homeowners planning whole-house RO treatment based on a water analysis.
- Households that need to match daily production and stored water to usage patterns.
- Installations with space for an RO unit, drainage, and any required storage and delivery equipment.
- Buyers who want capacity and configuration choices rather than a single fixed setup.
Important Information
- Obtain a feed-water analysis and have a qualified water-treatment professional confirm system suitability, capacity, and any necessary pre-treatment.
- Arrange installation by qualified professionals following the exact model's manual and applicable plumbing and electrical requirements. Confirm feed supply, pressure, drainage, power, and service clearance before ordering.
- RO operation produces a concentrate stream that requires suitable drainage. Water use and recovery depend on the model and operating conditions; no fixed recovery rate is stated here.
- Do not assume RO treatment alone makes microbiologically unsafe or untested water safe. Have a qualified professional determine any additional disinfection requirements and verify treated-water quality.
- Assess treated-water pH, alkalinity, and plumbing compatibility. Remineralization or other post-treatment may be appropriate based on testing.
- Storage, delivery equipment, UV treatment, remineralizers, and upgrades are included only where expressly specified for your selected order. The standalone option does not include a storage tank kit.
- Additional shipping charges may apply to orders with a 500-gallon storage tank. Confirm the full shipping cost before purchase.
- Replace pre-filters and membranes according to the manufacturer's instructions and operating conditions. Monitor system performance and test treated water periodically.
- No universal contaminant-removal percentage, health benefit, service-life guarantee, or certification claim is made in this description.
Frequently Asked Questions
What does the GPD rating mean?
GPD means gallons per day and describes rated daily RO water production, not instantaneous fixture flow. Actual production depends on feed-water temperature, pressure, dissolved solids, and membrane condition. Ratings are based on 77°F feed water and specified operating conditions.
Is a storage tank included?
The standalone configuration does not include a storage tank kit. You can select a configuration with a 165-, 220-, or 500-gallon storage tank kit, subject to compatibility with your planned installation.
How should I choose a system size?
Have a qualified installer review your water analysis, daily consumption, peak demand, feed-water conditions, and available space. Size the RO unit, storage tank, and delivery equipment together rather than relying on bathroom count alone.
Will I need remineralization or other treatment?
Additional treatment depends on your feed-water analysis and treated-water requirements. A qualified water-treatment professional should assess pre-treatment, disinfection, pH, alkalinity, and plumbing compatibility before recommending optional equipment.
What maintenance is required?
Follow the manufacturer's instructions for pre-filter and membrane replacement, system servicing, and any storage tank care. Monitor performance and test treated water periodically. Service intervals vary with water quality and usage.
Choose the production capacity and storage configuration that fit your water analysis and household demand. Confirm the installation requirements before ordering to build a practical whole-house RO setup for your home.
