UV Water Treatment Lamps & Sleeves

Why Replacing Your UV Water Treatment Lamp Annually Is Critical for Safe Drinking Water

Replacing the lamp in your UV water purification system every year is essential for maintaining the safety and effectiveness of your drinking water treatment. Over time, UV lamps lose their intensity—even if they still appear to be working. After 12 months of continuous use, the lamp may no longer emit enough UV light to properly disinfect your water, leaving it vulnerable to harmful bacteria, viruses, and other microorganisms.

For this reason, manufacturers and water treatment professionals strongly recommend replacing your UV lamp annually. Neglecting this simple maintenance step can compromise the quality of your water and put your household at risk.

To ensure maximum UV disinfection performance, many homeowners also replace the quartz sleeve—the protective glass tube that surrounds the lamp—during their yearly UV system maintenance. A clean or new quartz sleeve allows the UV light to penetrate more effectively, ensuring that your water is thoroughly treated and safe to drink.

Stay protected. Keep your UV system running at peak performance by replacing your lamp and quartz sleeve every 12 months.
