A distributor plate for a water softener system comprising: a top plate portion, a bottom plate portion, a perimeter edge, and a central opening, said top plate portion and bottom plate portion together forming rows of upwardly facing wells or cavities for receiving and retaining filter media on the topside of distributor plate and forming narrow fluid passage slits at the bottom edges of each upwardly facing well or cavity, the slits being situated at the interface of top plate portion and bottom plate portion, said upward facing wells or cavities are formed from a first plurality of chords traversing across said distributor plate in a first direction and a second plurality of chords traversing across said distributor plate in a second direction perpendicular to said first direction, such that said first and second plurality of chords (30,32) form sidewalls of said upward facing wells or cavities, and extend to a perimeter edge of said distributor plate, said bottom plate portion including a plurality of downward facing wells or cavities exposed thereon in a direction opposite said upward facing direction, said downward facing wells or cavities are formed from a third plurality of chords traversing across said bottom plate in said first direction and a fourth plurality of chords traversing across said bottom plate in said second direction, such that said third and fourth plurality of chords form sidewalls of said downward facing wells or cavities, and extend to said perimeter edge, whereby each lower chord provides a floor or upwardly facing surface for the well or cavity formed by two adjacent upper chords, said first plurality of chords having a cross-section of an isosceles trapezoid (30a-c) with a first chord base located at a bottom and whereby sides (30 b, c) angle outwards, such that each two adjacent chords form an upwardly facing well or cavity in the shape of an inverted trapezoid, said third plurality of chords having a cross-section of an isosceles trapezoid (40a-c) being inverted with respect to chords, thereby with its base facing towards top plate portion whereby two adjacent chords form a downwardly facing well or cavity. a top plate portion, a bottom plate portion, a perimeter edge, and a central opening, said top plate portion and bottom plate portion together forming rows of upwardly facing wells or cavities for receiving and retaining filter media on the topside of distributor plate and forming narrow fluid passage slits at the bottom edges of each upwardly facing well or cavity, the slits being situated at the interface of top plate portion and bottom plate portion, said upward facing wells or cavities are formed from a first plurality of chords traversing across said distributor plate in a first direction and a second plurality of chords traversing across said distributor plate in a second direction perpendicular to said first direction, such that said first and second plurality of chords (30,32) form sidewalls of said upward facing wells or cavities, and extend to a perimeter edge of said distributor plate, said bottom plate portion including a plurality of downward facing wells or cavities exposed thereon in a direction opposite said upward facing direction, said downward facing wells or cavities are formed from a third plurality of chords traversing across said bottom plate in said first direction and a fourth plurality of chords traversing across said bottom plate in said second direction, such that said third and fourth plurality of chords form sidewalls of said downward facing wells or cavities, and extend to said perimeter edge, whereby each lower chord provides a floor or upwardly facing surface for the well or cavity formed by two adjacent upper chords, said first plurality of chords having a cross-section of an isosceles trapezoid (30a-c) with a first chord base located at a bottom and whereby sides (30 b, c) angle outwards, such that each two adjacent chords form an upwardly facing well or cavity in the shape of an inverted trapezoid, said third plurality of chords having a cross-section of an isosceles trapezoid (40a-c) being inverted with respect to chords, thereby with its base facing towards top plate portion whereby two adjacent chords form a downwardly facing well or cavity.
