Abstract:
A fluid treatment device adapted to be connected to a fluid supply and a fluid exhaust, the device comprising:a housing, said housing comprising a base and a cover suitably engagable with said base to form a fluid-tight fit, said base and said cover cooperating to define a treatment chamber within said housing, said treatment chamber being adapted to accept a treatment cartridge for treating fluid in said treatment chamber; a retainer adjusted to removably retain said cover on said base; an in-line conduit configured to conduct fluid from the fluid supply to said treatment chamber and thence to the fluid exhaust, and to conduct fluid from the fluid supply to the fluid exhaust without passing through said treatment chamber; a valve disposed to control the flow of fluid through the in-line conduit; an adjustment mechanism configured so as to adjust said valve to control a portion of fluid flowing from the fluid supply that flows to said treatment chamber; wherein one of said base and said cover comprises a generally annular lip, and the other of said base and said cover defines a generally circular opening, said lip being sized so as to fit within said opening, whereby said lip and said opening cooperate to form a generally fluid-tight fit when said base and said cover are engaged, and whereby said lip is biased against an edge of said opening when a pressure inside said treatment chamber is greater than a pressure outside said treatment chamber.
