Abstract
A device for preventing leaks in a toilet that comprises a fill valve operatively connected to and disposed above a float. In certain embodiments an arm is rotably connected to the fill valve such that the arm comprises a pivot. A lever is, for example, pivotally connected to the pivot of the arm and biased towards the fill valve, wherein a flush actuator causes the lever to pivot away from the fill valve. The lever may comprise a first side and a second side joined at the pivot, wherein the first side weighs less than the second side, and wherein the distribution of weight between the first and second sides of the lever causes the lever to bias towards the fill valve.
Claims20
A leak prevention device for use in operation with a fill valve in a toilet, comprising:
- (a) the toilet fill valve having an arm extending therefrom;
- (b) a positionable locking lever connected to the arm, wherein the locking lever is configured to bias toward the fill valve;
- and
- (c) a pull connector extending from the locking lever.
A leak prevention device, comprising:
- a fill valve operatively connected to and disposed above a float in a toilet;
- an arm connected to the fill valve, wherein the arm comprises a pivot;
- a lever connected to the pivot of the arm and biased towards the fill valve, wherein a flush actuator causes the lever to pivot away from the fill valve.
A method of preventing a fill valve in a toilet from leaking, comprising:
- rotably connecting a fill valve arm to the fill valve, wherein the fill valve is positioned above a float;
- pivotally connecting a lever to a pivot of the fill valve arm, wherein the lever is biased towards the fill valve;
- and
- locking the fill valve by permitting a lower end of the lever to bias toward the fill valve when the lever is in a first position.
