Abstract
A rainhead (1) comprising: a tub member (3); an internal receptacle (8) in the tub member (3) having an internal wall (7) forming a weir spaced from an external wall (9) of the tub member (3); an inlet (4) arranged to direct water flowing from a gutter into the internal receptacle (8); and, a chute (11) between the internal wall (7) and the external wall (9), the chute (11) being arranged to receive water overflowing from the internal receptacle (8) to allow it to drain from the chute (11) through a chute outlet (13).
Claims20
An overflow device for enabling flow of water from a roof of a structure, along a box gutter of the structure, and into a downpipe, the overflow device comprising:
- a tub having a mounting wall, a front wall, two side walls, an internal wall positioned between the two side walls, and a base portion between the mounting wall and the internal wall and between the two sides walls;
- a weir formed by an upper edge of the internal wall, the weir and the internal wall dividing an interior of the tub into an internal receptacle above the base portion between the mounting wall and the internal wall and a chute between the front wall and the internal wall;
- a gutter receptor forming an inlet into the internal receptacle, the gutter receptor configured for receiving an end of the box gutter;
- a chute outlet from the tub, the chute outlet between the front wall and the internal wall;
- and
- a downpipe outlet within the base portion, the downpipe outlet configured for engaging the downpipe;
- wherein the overflow device is configured and arranged for mounting to a wall of the structure adjacent the end of the box gutter, the mounting wall facing the wall of the structure, the downpipe outlet engaging with the downpipe, and the end of the box gutter engaging with the gutter receptor;
- and
- wherein the overflow device is configured and arranged for water to flow from the roof of the structure, along the box gutter of the structure, pass through the inlet into the internal receptacle, and discharge through the downpipe outlet into the downpipe or, if either the internal receptacle or downpipe is blocked, the overflow device is configured and arranged for water to fill the internal receptacle, overflow the weir into the chute, and discharge to outside of the structure through the chute outlet.
