Skimmer box assembly
View Patent ↗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.
1. A skimmer box assembly, comprising:
a first fixed wall defining a first weir adjacent a main body of water;
a second weir positioned downstream of the first weir;
an entry well between the first weir and the second weir, wherein the entry well has a bottom that is surrounded by the first weir, the second weir, and two side walls;
a collection box downstream of the second weir and in fluid communication with the first and second weirs; and
an outlet from the collection box to allow outflow of water.
2. The skimmer box assembly of claim 1 , further comprising a weir door positioned in the second weir.
3. The skimmer box assembly of claim 2 , wherein the weir door is hinged to permit rotation within an arc of approximately 90°.
4. The skimmer box assembly of claim 2 , wherein the weir door includes a float to facilitate movement of the weir door in correspondence with a water level inside the skimmer box assembly.
5. The skimmer box assembly of claim 2 , wherein the first weir and the second weir define rectangular boxes.
6. The skimmer box assembly of claim 2 , wherein when the weft door is rotated to a vertical position an upper most portion of the weft door remains below a designated water level of the main body of water.
7. The skimmer box assembly of claim 2 , wherein an entry to the first weir is an elongated slot.
8. The skimmer box assembly of claim 7 , wherein the slot is open at the top.
9. The skimmer box assembly of claim 7 , wherein the slot is located in an upper section of the first weir.
10. The skimmer box assembly of claim 1 , wherein the outlet is located adjacent a bottom of the collection box.
11. The skimmer box assembly of claim 1 , wherein low water delivery pipes are in fluid communication between the main body of water and the collection box.
12. The skimmer box assembly of claim 1 , wherein the main body of water is a swimming pool.
13. The skimmer box assembly of claim 1 , wherein the entry well further includes a rear wall.
14. The skimmer box assembly of claim 13 , wherein the entry well further includes an exit to the second weft, the rear wall being disposed at least partially above the exit.
