Why replace your UV lamp annually?
UV lamps lose effectiveness after about 9,000 hours (12 months) of use. Even if the light is still on, it may no longer provide adequate disinfection. Replacing the lamp every year ensures your system continues to protect your water.

The role of the quartz sleeve
This sleeve acts as a barrier between the UV lamp and the water, while still allowing UV light to pass through. Over time, minerals and buildup can cloud the sleeve, reducing the lamp’s ability to disinfect. Regular maintenance or replacement helps keep your system running efficiently.
