Patent attributes
A skimmer box assembly for a swimming pool includes a first weir adjacent a main body of the swimming pool, and a second weir is positioned downstream of the first weir. An entry well is provided between the first weir and the second weir to allow passage of water from the main body of the swimming pool, and a collection box is provided downstream of the second weir and in fluid communication with the first and second weirs. An outlet from the collection box allows outflows of water, and a weir door may be positioned in the second weir with the weir door hinged to permit rotation with an arc of 90° or thereabouts. The weir door is preferably located opposite the entry well and preferably includes a float to facilitate movement of the weir door in correspondence with the water level inside the skimmer box assembly.
