Abstract
A water level control system and device is provided which maintains a desired running level of water in a surge tank connected to a pool or other body of water by facilitating automatic drainage of precipitation water from the body of water. The water level control system includes a water level control device configured to open and close a drain in the surge tank. The water level control device can adopt an open position when water in the surge tank is at a first level slightly above the running level, and a closed position in the presence of surge water or water displaced by bathers causing a rapid water rise in the surge tank above first level.

A water level control device for a water pool comprising:
- a surge tank in fluid communication with the water pool by means of an overflow conduit;
- a device body mounted onto a fluid drainage conduit of the surge tank;
- a lever arm pivotably carried by the device body, wherein the lever arm is pivotable relative to the device body about a rotation axis;
- a float provided on the lever arm on a first side of the rotation axis;
- and
- a closure flap provided on the lever arm on a second side of the rotation axis generally opposite to the first side;
- wherein
- the water level control device is configured to adopt:
- an open position in which the lever arm is pivoted in a first direction, and
- a closed position in which the lever arm is pivoted in a second direction opposite to the first direction, and further in which the float is arranged higher than in the open position and the closure flap is arranged lower and closer to the device body than in the open position.
A water level control device for a water pool comprising:
- a surge tank in fluid communication with the water pool by means of an overflow conduit;
- a device body comprising a sleeve-shaped portion mounted onto a fluid drainage conduit of the surge tank;
- a lever mount arm extending from the device body;
- a lever arm pivotably mounted to the lever mount arm, wherein the lever arm is pivotable relative to the device body about a rotation axis;
- a float provided on the lever arm on a first side of the rotation axis;
- and
- a closure flap provided on the lever arm on a second side of the rotation axis generally opposite to the first side;
- wherein
- the water level control device is configured to adopt:
- an open position in which the lever arm is pivoted in a first direction, and
- a closed position in which the lever arm is pivoted in a second direction opposite to the first direction, and further in which the float is arranged higher than in the open position and the closure flap is arranged lower and closer to the device body than in the open position.

- and further wherein
- the water level control device is configured to begin moving from the open position towards the closed position when a water level of a water body contacting the float starts rising above the sleeve-shaped portion of the device body.
