What Components Are in a UV System?

While the exact components of a UV system vary between different models and brands, certain components require routine maintenance and replacement in order to make sure that your UV system is effectively treating your water. UV lamps, UV quart sleeves and O-rings are the three most common UV system components that require scheduled maintenance.

UV Lamps

UV water treatment systems rely on specialized bulbs that emit UV rays to neutralize contaminants in your water system. These UV lamps are fueled by mercury and produce UV arcs to neutralize bacteria in your water.

UV Quartz Sleeves

The UV quartz sleeve provides a safe, transparent barrier between your UV bulb and the rest of your UV system.

O-Rings

O-Rings form water-tight seals on your UV system and ensure that water doesn’t leak from the chamber of your system.

Why Should I Maintain My UV System?

As the mercury in your UV system is used, the mercury begins to diminish, and the lamp will struggle to generate a sufficient UV output to properly neutralize bacteria and contaminants in your water as a result. Microorganisms and bacteria will then be free to reproduce in your water system as they are left unchecked by the germicidal wavelengths emitted by your UV light. If your mercury level is left undiagnosed for too long, the ballast in your UV lamp can become damaged from overuse, resulting in costly repair parts and services.

Your quartz sleeve is regularly exposed to hardness, manganese and iron that can cloud the sleeve. If your quartz sleeve becomes corroded and lacks transparency, the UV rays will not properly reach the water in your system. Excess corrosion can even cause the quartz sleeve to crack or break entirely.

Lastly, if your O-ring is not regularly replaced, water can leak from the chamber of your system and damage your UV system’s electrical components.

How Often Do I Replace My UV Lamps & Components?

You can find information on how often you should change your UV lamps and additional components below.

UV Lamps

Replace once every 2 years.

Quartz Sleeves

Replace once every 4 years, or approximately 25,000 operating hours.

O-Rings

Replace once every 2 years while performing UV lamp replacement.

UV Sensors

Replacement should be considered once every 4-6 years.

How to Replace a UV Lamp

UV lamps vary by configuration, but certain steps can be taken to safely uninstall and replace your UV lamp.
  1. Turn off your home water source
  2. Turn off the power source feeding power to your UV system
  3. Wait for UV system to cool
  4. Use gloves to unscrew the safety cap
  5. Remove the UV lamp and sleeve and discard old O-rings
  6. Replace O-rings and new lamp and sleeve into your system
  7. Make sure lamp alignment is correct and perform a leak check after turning on water source

How Do I Maintain My UV System?

While the exact components of a UV system face varying degrees of wear and tear, following the above replacement schedule is an excellent way to maintain a highly efficient, functioning UV system.
