USWF Replacement for 602732 Quartz Sleeve | Fits the VIQUA C/C4/D/D+/D4/D4 premium Series UV Systems

The quartz sleeve is an important part of the UV water treatment system. It protects the UV lamp from coming in contact with the water while allowing the UV light to permeate the water. Minerals from the water will build up on the sleeve over time causing the sleeve to become cloudy not allowing the UV light to permeate the water as effectively. How quickly the minerals build up on the sleeve will vary depending on your water hardness, and if you have hardness of over 7 gpg you should install a water softener to treat the water before your UV system. Once the mineral layer on the quartz sleeve cannot be removed via cleaning, or the sleeve cracks or breaks it's time to get a replacement. USWF-350044 is a replacement for VIQUA 602732. For use in the VIQUA C/C4/D/D+/D4/D4 premium series of ultraviolet water treatment systems. All quartz sleeves come with 2 replacement o-rings.

Ultraviolet (UV) water treatment systems use specialized lamps that emit UV light at a wavelength designed to disrupt the cellular function of microorganisms. This light damages the DNA of bacteria, viruses, and other pathogens, preventing them from reproducing or causing infection. Because UV treatment neutralizes these organisms without chemicals, it offers a clean, safe, and low-maintenance solution for water disinfection. Once installed, the UV lamp operates continuously, disinfecting water around the clock with only minimal annual maintenance required.

Since UV light travels in a straight line and doesn't penetrate solids or shadows, prefiltration is essential. Removing sediment, silt, and other particles ensures the UV light can effectively reach and treat any microorganisms present. Additionally, minerals found in hard water can accumulate on the quartz sleeve that protects the UV lamp, potentially reducing its effectiveness. In areas with hard water, a water softener is recommended as part of the pretreatment process.

For water drawn from natural sources, professional testing and proper treatment are strongly recommended before it's used for drinking, cooking, bathing, or recreational purposes. UV disinfection provides a dependable, chemical-free, and environmentally responsible method for treating water and protecting against microbiological contaminants.
