Learn how UV light systems keep your water safe. Find answers about UV alarms, bulb replacement, and quartz sleeve cleaning for better water quality.
Ultraviolet (UV) light systems are an effective, chemical-free way to disinfect your home’s water supply. They work by using UV-C rays to neutralize harmful microorganisms, including bacteria, viruses, and other pathogens that may be present in well or municipal water sources. If you’re new to UV light technology. Once you’re familiar with the basics, it’s helpful to understand how to maintain your UV system for peak performance. Below are some of the most common questions our customers ask about the UV light systems we install and service.
Why Is My UV Light Beeping? Power Outage?
If your UV light system begins beeping, the controller is alerting you that the bulb’s service life has reached its limit—usually after 365 days. This does not necessarily mean your UV bulb has stopped working; however, the light intensity may have diminished enough to affect water disinfection performance. The manufacturer recommends replacing the UV bulb annually to ensure consistent protection. In some cases, power interruptions or system malfunctions can also trigger the alarm. Resetting the controller can silence the beeping and restart the countdown timer, but it’s important to schedule professional service to replace the bulb or diagnose any issues. Customers enrolled in our UV light maintenance program benefit from accurate service records and timely bulb replacements, ensuring their system continues to operate safely and effectively.
Why Does the Quartz Sleeve Need Cleaning or Replacement?
The UV light bulb is protected by a clear quartz sleeve that sits directly in contact with pressurized water. Over time, the sleeve can accumulate mineral buildup, discoloration, or etching depending on the water chemistry. This buildup blocks the ultraviolet rays, reducing the light’s ability to disinfect the water efficiently. We recommend inspecting and cleaning the sleeve whenever the UV bulb is replaced. Often, a simple cleaning restores clarity, but if staining or etching remains, replacing the sleeve is the best option. Routine maintenance ensures your UV water filtration system continues providing clean, safe water for your home year-round.
