The Crystal Quest Whole House Reverse Osmosis System is a configurable point-of-entry reverse osmosis system designed to support treated water throughout a home or larger property with properly reviewed daily water demand. It is available in listed production options from 200 GPD to 7000 GPD, with standalone configurations or optional atmospheric storage tank kits where available. Buyers can choose from listed brass rotary and stainless steel rotary pump options where available for the selected system. Each system includes prefiltration to help protect the reverse osmosis membranes, while optional add-ons may vary by selected GPD model and may include UV sterilization, remineralization or alkalizing post-treatment, controller upgrades, TDS monitoring, chemical pump outlet, blending valve, and other listed options. Because output is rated at 77°F water and source-water conditions affect performance, the exact system should be selected based on daily water demand, feed pressure, TDS, hardness, storage needs, installation space, and licensed installer guidance.
This Crystal Quest system is designed for properties that need reverse osmosis treatment beyond a single drinking-water faucet. Available capacities range from smaller residential daily demand to larger 4000, 5000, and 7000 GPD applications, giving buyers a way to size the system around actual water use.
The system can be ordered as a standalone reverse osmosis unit or paired with an atmospheric storage tank kit where available. Official Crystal Quest product information lists 165, 220, and 500 gallon atmospheric storage tank options, while some dealer/store data may reference 550 gallon kits. Confirm the selected tank size and dimensions against the exact product variant before installation.
Reverse osmosis treatment can reduce dissolved minerals, so post-treatment planning may be appropriate when pH, mineral balance, or plumbing compatibility is a concern. Crystal Quest lists remineralizer and alkalizing post-treatment options that may be selected based on the system size and water-treatment goals.
System performance is tied to source-water conditions. Crystal Quest manual materials note that systems are rated with 77°F water, and higher TDS and/or lower water temperature can reduce membrane production. Properties outside the stated constraints should be reviewed before purchase.
This whole house reverse osmosis system is designed for homes and properties that need more than point-of-use drinking water filtration. It supports larger daily water demand with multiple GPD options, pump selections, and optional storage tank kits.
Choose the system by daily gallon output, storage tank size, pump option, feed-water quality, and available installation space. Larger systems should be checked against the exact dimensional, feed-flow, and installation requirements for the selected model.
