Abstract
A fill valve system with a float nested in a container connected to the fill valve and a siphon device passing water out of the container into the toilet tank, with the siphon device having an air vent dimensioned such that: (i) tank refilling is delayed until after the flush valve closes; (ii) the fill valve is not turned on by small leaks in the tank; and (iii) the fill valve turns off when it encounters large leaks in the tank.
Claims25
A fill valve system, comprising:
- (a) a water supply member;
- (b) a fill valve in fluid communication with the water supply member;
- and
- (c) a float assembly connected to the fill valve, the float assembly comprising:
- (i) a container,
- (ii) a float nested in the container, wherein the position of the float in the container turns the fill valve on and off, and
- (iii) a siphon device in fluid communication with the container.
4 more elements
A method of operating a fill valve, comprising:
- (a) providing a fill valve having a float assembly connected thereto, wherein the float assembly comprises a container with a float nested in the container, wherein the position of the float in the container turns the fill valve on and off, and wherein the fill valve and float assembly are positioned in a toilet tank;
- (b) draining tank water around the fill valve and float assembly;
- and
- (c) siphoning water out of the container to drain the container and thereby lower the float to turn the fill valve on.

A fill valve system, comprising:
- (a) a water supply member;
- (b) fill valve in communication with the water supply member;
- and
- (c) a float assembly connected to the fill valve, the float assembly comprising:
- (i) a container having a first compartment and a second compartment,
- (ii) the float nested in the first compartment of the container, wherein the position of the float in the first compartment turns the fill valve on and off, and
- (iii) a fluid flow path in the fill valve to divert a small portion of refill water into the second compartment of the container.
