Patent ID: 8091581

Claim:
A fluid flow control device comprising: a valve housing having an inlet flow reducer aperture, valve element, and an outlet aperture having fluid communication between a valve element chamber and the inlet aperture and the outlet aperture; a valve washer positioned within the valve housing being moveable between an inlet closed position and an outlet closed position, the washer being moveable to the outlet closed position in response to a reverse fluid flow from the outlet aperture toward the inlet flow reducer aperture, the washer moveable to the outlet closed position responsive to forward fluid flow through the inlet flow reducer aperture toward the outlet aperture; the valve washer attached to a rod holder proximate end, the valve washer and the rod holder dimensioned for movement within the valve housing through the outlet aperture, the valve washer and the rod holder, further having a length dimension for displacing the washer away from contact with the outlet aperture, a float rod detachably connected to the rod holder distal end; and a float pivotally connected to the float rod proximate end by a threaded float connector, the float responsive to level changes within a reservoir wherein a fluid level below a desired level causes the float to lower thereby lowering the rod holder thus tilting the valve washer away from the outlet aperture; a generally open water keel attached below the float for providing an up or down float adjustment by means of the threaded float connector threaded into the water keel said adjustment achieved by clock-wise or counter-clock-wise rotation of the body of the float according to the desired fluid level; and a fluid-absorbing tell-tail attached to a flat washer slid onto the float rod distal end proximate the rod holder for indicating fluid flow or fluid closure movement of the fluid within the valve housing through the outlet aperture.
