A Box Gutter System and Sump Overflow Device
Abstract An overflow device comprising a sump for a box gutter includes a primary sump receptacle with first and second end walls, a pair of sidewalls extending between and a basal wall, with a primary outlet port for the discharge of water; the second end walls is common in forming a first end wall of a second sump receptacle having a second end wall, opposed sidewalls, a bottom wall and a secondary outlet for the discharge of water. The common wall has an upper edge spaced below the upper edges of each of the first end wall of the primary receptacle, the second end wall of the secondary receptacle and of the opposed sidewalls of each receptacle. The overflow device has a width between at least equal to the width of the box gutter whereby the overflow device is adapted to be installed in relation to a first box gutter section such that: the first end wall of the first sump receptacle extends transversely with respect to the box gutter to enable the overflow device to be sealed to the first section of the box gutter, the overflow device is adapted to be installed, if required, in relation to a second section of the box gutter such that the second end wall extends transversely with respect to the box gutter for sealing the overflow device to the second section of the box gutter; and such that, with the overflow device so installed, water can flow from the first section of the box gutter, over an upper edge of the first end wall of the primary receptacle, into the primary receptacle and discharge through the primary outlet port, and with the primary outlet port sufficiently blocked, water can overflow an upper edge of the common wall, into the secondary receptacle and through the secondary outlet port. dr 4
