How to Clean a UV Sleeve?

How often should a quartz sleeve be cleaned?

Regularly cleaning your quartz sleeve is important because contaminant buildup can hinder the UV transmission and reduce its effectiveness. It is highly recommended that the quartz sleeve be cleaned every 12 months when replacing the UV lamp, and replaced every 24-36 months. Depending on the quality of your water, you may need to pull out the quartz sleeve and clean it every few months.
