Toilet fill valve with valve lock
Disclosed are various embodiments of a lockable toilet fill valve and methods according to the present invention. In one embodiment, a toilet fill valve includes a float/arm assembly. The toilet fill valve is closed when the float/arm assembly is disposed in a first position. The toilet fill valve being open when the float/arm assembly is disposed in a second position. A valve lock is associated with the float/arm assembly. The valve lock includes an unlock position and a lock position, wherein the valve lock fixes the float/arm assembly in the first position when the valve lock is in the lock position.
1. A method for controlling the operation of a toilet fill valve having a float/arm assembly and a rocker switch, the rocker switch being configured to toggle between a lock position and an unlock position, the method comprising the steps of:
closing the toilet fill valve when the float/arm assembly is disposed in a first position;
opening the toilet fill valve when the float/arm assembly is disposed in a second position; and
moving the rocker switch with respect to a seat for the rocker switch to place the rocker switch in the lock position to fix the float/arm assembly in the first position, wherein the rocker switch engages the float/arm assembly when in the lock position to hold the float/arm assembly in the first position.
2. A lockable toilet fill valve, comprising:
a toilet fill valve with a float/arm assembly;
the toilet fill valve being closed when the float/arm assembly is disposed in a first position;
the toilet fill valve being open when the float/arm assembly is disposed in a second position;
a valve lock associated with the float/arm assembly, the valve lock includes an unlock position and a lock position, wherein the valve lock fixes the float/arm assembly in the first position when the valve lock is in the lock position; and
wherein the valve lock further comprises a rocker switch and a seat for the rocker switch, the rocker switch having a first end and a second end, the first end of the rocker switch being configured to move with respect to the seat and cause the float/arm assembly to be in the first position.
3. The system of claim 2 , wherein a protrusion extends from the rocker switch and engages a lip on the fill valve disposed relative to the rocker switch, thereby holding the rocker switch in one of the lock and unlock positions.
4. The system of claim 2 , wherein the rocker switch further comprises a pin that contacts a portion of the arm of the float/arm assembly when the rocker switch is in the lock position.
5. The system of claim 2 , wherein the rocker switch further comprises a pin that engages a portion of the arm of the float/arm assembly when the rocker switch is in the lock position.
6. The system of claim 2 , wherein the rocker switch is located on a cap of the toilet fill valve.
7. The system of claim 2 , wherein the second end of the rocker switch is configured to move with respect to the seat and cause the float/arm assembly to be in the second position.
8. The system of claim 2 , wherein a hook extends from the rocker switch and engages the float/arm assembly when the rocker switch is in the lock position.
9. The system of claim 8 , wherein the hook comprises a tee.
