It doesn't happen often, but there are times when something minor gets damaged and it stops the entire UV water treatment unit working.
It could be frost, an accidental knock, or the sleeve spring gets lost during a UV lamp change.
These little parts can be difficult to find, which is why we stock the handy Luminor Blackcomb Parts Kit which contains the bracket, gland nut, o-ring and sleeve spring.
This Luminor Blackcomb parts kit is suitable for all series of the Luminor UV water treatment systems - LB4, LBH4, LB5, LB6, LBH5 and LBH6.
