The present invention relates to a point-of-use water treatment system unit. The unit includes a filter housing assembly having a filter tank assembly and a closure which utilizes a handle and cammed reciprocating lock blades to secure the closure to the filter tank assembly. A UV tank assembly includes a planar baffle plate and a vaned baffle plate to induce plug flow about a UV lamp assembly. A UV lamp assembly is used which simultaneously electrically and sealingly mounts to a UV tank assembly and electrical cap assembly using a bayonet mount. A bi-planar manifold assembly is used to interconnect components of the WTS unit and to provide an envelope for accommodating a water pipe assembly. The bi-planar manifold assembly enhances the compactness of the design of the WTS unit. Also, a support plate is disclosed which provides support to subcomponents of the WTS unit while also dissipating heat from a UV tank assembly.

1. A replaceable UV bulb assembly for a UV subassembly of a point- of-use water treatment system, the system in fluid communication with a water supply comprising:a connector adapted to mechanically mount to the UV subassembly, said connector having an internal surface that faces an interior of the UV subassembly and an external surface that is visible from an exterior of the UV bulb assembly when said replaceable UV bulb assembly is mechanically mounted to the UV subassembly, the connector defining an aperture having a cross section; a UV bulb affixed to said connector, said bulb contained within the UV subassembly when said connector is mounted to the UV subassembly; and a light pipe mounted in the aperture so that the light pipe fills the entire cross section, said light pipe extending from said internal surface to said external surface, wherein said connector, said UV bulb, and said light pipe form an integrated unit that is removable and replaceable relative to the UV subassembly while the point-of-use water system remains in full fluid communication with the water supply. 2. A replaceable UV bulb assembly for a UV subassembly of a point-of-use water treatment system, the system in fluid communication with a water supply comprising:a connector adapted to mechanically mount to the UV subassembly, said connector having an internal surface that faces an interior of the UV subassembly and an external surface that is visible from an exterior of the UV bulb assembly when said replaceable bulb assembly is mechanically mounted to the UV subassembly; a UV bulb affixed to said connector, said bulb contained within the UV subassembly when said connector is mounted to the UV subassembly; a light pipe mounted to said connector, said light pipe extending from said internal surface to said external surface, wherein said connector, said UV bulb, and said light pipe form an integrated unit that is removable and replaceable relative to the UV subassembly while the point-of-use water treatment system remains in full fluid communication with the water supply; and wherein said connector includes a handle and defines a light pipe opening, said light pipe fitted within said light pipe opening. 3. The UV bulb assembly of claim 2 wherein said light pipe is manufactured from a light transmissive material.4. The UV bulb assembly of claim 3 wherein the water treatment system includes a bulb cover covering the UV subassembly, the bulb defining an aperture, said light pipe adapted to extend from said connector through the aperture in the bulb cover, whereby said light pipe is visible from an exterior when the bulb cover is installed on the water treatment system.5. A point-of-use water treatment system comprising:a housing; a UV subassembly mounted within said housing, said UV subassembly including a UV tank defining a UV bulb chamber; a replaceable UV bulb cartridge mounted to said UV subassembly, said UV bulb cartridge being removable and replaceable as a single integrated unit relative to said UV subassembly, said UV bulb cartridge including a connector mechanically mounted to said UV tank and a bulb projecting into said UV bulb chamber, said UV bulb cartridge including a bulb joined with the connector, and a gasket sealingly engaging the bulb and the connector, the UV bulb cartridge further including an internal surface facing the interior of said UV bulb chamber, an external surface facing the exterior of said water treatment system, and a light pipe mounted to said UV bulb cartridge and extending between said internal surface and said external surface, whereby said light pipe is visible from an exterior of the water treatment system. 6. The water treatment system of claim 5 wherein said housing includes a bulb cover for enclosing said UV subassembly within said housing, said bulb cover defining an aperture, said light pipe extending through said aperture, whereby said light pipe is visible from an exterior of the water treatment system when said bulb cover is installed on said housing.7. The water treatment system of claim 6 wherein said connector defines a light pipe opening, said light pipe press-fitted within said light pipe opening.8. The water treatment system of claim 7 wherein said light pipe is manufactured from a light transmissive material.9. The water treatment system of claim 8 wherein said connector includes an axis, said light pipe being disposed coaxially within said connector.10. A lamp for a point-of-use water treatment system comprising:a connector adapted to secure the lamp to the water treatment system; a bulb mounted to and extending from the connector; a gasket interposed between the bulb and the connector, the gasket sealing against the a lamp exterior portion and a lamp interior portion, said lamp interior portion being concealed from view when the lamp is mounted in the water treatment system; and a light pipe disposed in said connector and providing illuminating communication between said interior portion and said exterior portion, wherein said connector, said bulb, and said light pipe form an integrated unit that is removable and replaceable as a single cartridge. 11. The lamp of claim 10 wherein the light pipe is mounted adjacent said bulb so that when said bulb is activated, the light pipe transmits radiation from the bulb through the base to the exterior portion.12. The lamp of claim 10 wherein the base mounts to a tank assembly to form a closed pressure vessel.13. The lamp of claim 10 wherein the bulb is a UV bulb.14. The lamp of claim 10 wherein the base includes an electrical connector element.
