Control valves, such as softener and filter valves, need regular maintenance too!

UV bulbs should be replaced at least every twelve months or after every 9,000 hours of use. After that time, disinfection will no longer occur and lessen protection from microbiological matter.
Whenever UV bulbs are replaced, it is helpful to replace the o-rings as well.
