Abstract
A leak prevention device is provided for use in operation with a fill valve with a fill valve arm in a toilet tank. The device may comprise a pivotable locking lever having a first portion positioned to pivot into and out of contact with the fill valve arm or an extension thereof. The fill valve arm affects actuation of the fill valve to modulate fluids from entering the toilet tank, wherein the pivotable locking lever is operable to contact or is capable of contacting the fill valve arm thereby prohibiting the operation of the fill valve.
Claims24
A leak prevention device for use in operation with a fill valve seated on a post in a toilet, the device comprising:
- a locking lever pivotable about a central pivot comprising a bias element being oriented to bias a first portion of the locking lever pivotally about the central pivot;
- wherein the first portion is operable to be pivotally positioned to prevent movement of a fill valve arm in communication with the fill valve.
A leak prevention system for use in operation with a fill valve seated on a post in a toilet, the system comprising:
- a float slidably coupled to the post underneath the fill valve;
- a link with an upper end and a lower end, the lower end being rigidly coupled to the float;
- an arm pivotally connected to the fill valve and pivotally connected to the upper end of the link;
- a locking lever pivotally connected to a central pivot underneath the arm and the fill valve, wherein a first portion of the locking lever is configured to pivot about a central pivot and bias towards the link.
A method of preventing a toilet tank with a fill valve seated above a post from leaking, the method comprising:
- pivotally connecting a locking lever to a central pivot, wherein a first portion of the locking lever is operable to bias away from the post;
- and
- preventing the fill valve from actuating fluid flow into the toilet tank by pivoting the first portion of the locking lever about the central pivot towards a fill valve link mechanically attached to a float slidably couple to the post so that an actuating arm pivotally connected to the link and the fill valve is prevented from translating.
