System and apparatus for controlling fluid flow in drainage systems with a cage device

A fluid control system to control fluid flow within a drainage system, the fluid control system comprising:

• a cage coupled to an interior sidewall of a structure of the drainage system, wherein the cage at least partially surrounds an aperture of the interior sidewall, wherein the cage includes a plurality of bars including a first bar, a second bar, a third bar, and a fourth bar, wherein the first bar extends from a top of the cage to the interior sidewall thereby forming a side of the cage and a bottom of the cage, wherein the second bar and the third bar each extend from the first bar to the top of the cage without coupling to the interior sidewall, and wherein the bottom of the cage is in a gravitational direction relative to the top of the cage;
• and
• a float device encapsulated within the cage, wherein while in a resting state the float device covers the aperture of the interior sidewall of the structure of the drainage system, wherein fluid flow is allowed through the aperture of the interior wall when the float device is dislodged from the resting state to an elevated position, wherein a cylindrical upper portion of the cage is formed of the plurality of bars, wherein the fourth bar is coupled to the sidewall of the structure of the drainage system via a first coupling bar and a second coupling bar that each extend away from the sidewall of the structure of the drainage system, and wherein the fourth bar prevents the float device from contacting the sidewall above the second coupling bar.
