Abstract: A back-water trap unit comprises a housing having an outer perimetric wall sealed to a base to define an enclosure, and a removable housing cover comprising inlet apertures. An interior wall, shorter than the housing wall, is sealed to the base to define an inner compartment and an outer compartment within the enclosure, the inner compartment being sealed by a cover secured to the upper interior wall edge and the inside of the housing wall. A flapper valve secured to the interior wall within the inner compartment is rotatable in response to liquid pressure to open or close an inlet aperture proximate the lower interior wall edge. An outlet through the housing wall as high as or above the upper edge of the inlet aperture allows discharge of fluid from the inner compartment, while the flapper valve prevents unwanted back-flow from the inner compartment to the outer compartment.

The heating unit (17) protrudes into the evaporator chamber (27) with no conductive contact to the side walls (37).

Abstract: A self-cleaning assembly comprising an enclosed casing 1 with a movable piston 31 and filters 32,33 therein. The preferred assembly has a casing 1 with a dirty water inlet 5, a first outlet 6 for clean filtered water and a second outlet 7 for the removal of sludge from the casing. The filter assembly is constructed and arranged to provide, in its normal operating mode, a liquid flow path through the filter 32,33 in a first direction between the dirty water inlet 5 and the clean water outlet 6 and, in a cleaning mode, to provide a liquid flow path in a second direction between the dirty water inlet 5 and the sludge outlet 7. In the cleaning mode, the movable member 31 compresses the filters 32,33 during the liquid flow in the second direction and contaminant is released therefrom for removal from the filter assembly via the second outlet 7. In an alternative embodiment, the sludge outlet 7 is omitted and sludge is removed from the casing via the outlet 6.
