Abstract
A water treatment system 20 for filtering and treating contaminants in water includes a UV lamp assembly 24 coaxially received within a filter assembly 26. A valve system prevents water from being spilled from the filter assembly when the filter assembly is removed from the base unit 22 and the lamp assembly so that the lamp and filter assemblies are independently replaceable. The valve system includes a check valve 102 controlling flow between the lamp and filter assemblies.
