Bracket system for securing a single-lever-valves and associated water pipework to a support board

A bracket system for securing two single-lever-valves back-to-back on opposite sides of a support board, comprising:

• first and second base brackets each having first, second, third and fourth sides respectively defining first and second central spaces for accommodating a single lever valve in each central space, said first and second base brackets each having first and second opposite faces, wherein said first and third sides of each base bracket are parallel and opposite each other and said second and fourth sides of each base bracket are parallel and opposite each other, wherein each of said first, second and fourth sides of each base bracket comprises a notch on said first face, wherein each notch is sized to accommodate part of the circumference of a water pipe, wherein said notch of said first and third sides of each base bracket are opposite each other, and said notch of said second and fourth sides of each base bracket are opposite each other, each base bracket further comprising:
• a male tongue for attaching to a support board, wherein said male tongue projects at a perpendicular angle from one side of said second face, wherein said male tongue defines board-securing apertures,
• a pair of female tongues, wherein said pair of female tongues project at a perpendicular angle from one side of said second face, wherein said pair of female tongues define board-securing apertures, wherein said male tongue is on the opposite side of said second face with respect to said pair of female tongues,
• wherein said male tongue of said first base bracket can fit between said pair of female tongues of said second base bracket, and said male tongue of said second base bracket can fit between said pair of female tongues of said first base bracket:
• and
• means for attaching water pipe hardware to notches on said first side of each base bracket.
