Whole house and commercial UV water treatment

6 GPM ultraviolet disinfection for residential water systems

The Crystal Quest 6 GPM UV Water Sterilizer System adds a chemical free ultraviolet treatment stage to a properly designed residential or whole house water system. Model CQE-UV-00102 combines one germicidal lamp with a 304 stainless steel reactor chamber, an audible lamp failure alert, and an LED power indicator for continuous operation.

Use this system as the final treatment stage after the required sediment filter and any water treatment needed to meet the required water quality ranges. Correct sizing, water preparation, installation, and maintenance are essential for reliable UV performance.

Who this 6 GPM UV system is for

Homes with matching water demand

Suitable for a properly sized residential water treatment system when peak water use does not exceed 6 gallons per minute.

Well water treatment

Adds a final UV treatment stage after the water has been tested and treated to meet the required limits for cloudiness, hardness, iron, manganese, tannins, and UV light transmission.

Whole house filtration

Fits whole house applications after a qualified professional confirms water demand, water quality, plumbing, electrical service, and local requirements.

Treatment sequence

How ultraviolet disinfection works in the water treatment path

Water passes through the stainless steel chamber, where one UV lamp exposes it to ultraviolet light. The system is designed for applications requiring up to 99.99% reduction of bacteria, viruses, and protozoa when it is correctly installed, operated, and maintained within the required water conditions.

2Complete pretreatmentCorrect sediment and other out of range conditions.
3Install the UV stagePlace the UV system after a 5 micron sediment filter.
4Distribute treated waterUse UV as the final treatment before branch lines.

Continuous treatment without chemical addition

  • Adds no treatment chemicals to the water
  • Uses an axial flow chamber made from 304 stainless steel

  • Tannins below 0.1 mg/L
  • UV light transmission above 75 percent

Treat water that falls outside these ranges before it reaches the UV system.

Site requirements

  • Indoor location protected from weather, freezing, flooding, dust, and direct sunlight
  • 5 micron sediment filter installed before the UV chamber

Ongoing care

Maintain UV output and service access

Keep the lamps operating

Operate the UV lamps continuously. Repeated switching shortens lamp life and interrupts treatment.

Replace lamps annually

Replace the CQE-UV-03102 lamp after approximately 9,000 hours or one year of continuous use.

Clean the quartz sleeves

Inspect and clean the sleeves as water conditions require. Replace the sealing rings annually.

Disconnect electrical power and stop water flow before maintenance. Use the installation and operation manual for complete safety and service steps.

Before you buy

Common questions about the 6 GPM UV system

Does this system replace sediment filtration?

No. Install a 5 micron sediment filter before the UV system. Additional water treatment may be needed when the source water does not meet the required water quality ranges.

Can the unit be installed outdoors?

No. Install it indoors in an area protected from rain, dust, flooding, freezing, and direct sunlight.

How often are the lamps replaced?

Replace the UV lamp after approximately 9,000 hours or one year of continuous operation. Use the installation and operation manual for the complete maintenance steps.

Can the chamber be mounted vertically?

Yes. Mount the chamber horizontally or vertically. For vertical installation, place the lamp connector at the top and leave enough open space to service the system.

What must the installer supply?

Pipe, shutoff valves, and fittings are not included. Plan for union connections, a flow restrictor, and a bypass assembly.
