You should inspect the parts of your UV light water filtration system every 3-6 months for signs of wear or failure, and the whole system should be serviced at least once a year.
System parts should typically be replaced as follows:
- UV lamps: Depending on the system, after 9,000-12,000 hours (or 12 months) of use
- Quartz sleeves: Every 2-3 years
- O-rings: Annually
- Electronic ballasts: Every 5-10 years
