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 and arm assembly. The toilet fill valve is closed when the float and arm assembly is disposed in a first position. The toilet fill valve is open when the float and arm assembly is disposed in a second position. A side lever is associated with the float and arm assembly. The side lever includes an unlock position and a lock position. The side lever includes a hook that engages the float and arm assembly to restrict movement of the float and arm assembly when in the lock position and allow movement of the float and arm assembly when in the unlock position.

A toilet having a one piece structure, a flush valve, and a seal. The structure includes a base having a fluid channel in fluid communication with a bowl; a tank having an internal compartment; a wall disposed between the tank and the base, the wall having an opening fluidly connecting the internal compartment and the fluid channel; and a retaining structure in the internal compartment. The flush valve has a valve body including an inner wall, which is disposed in the opening and extends from a first end in fluid communication with the internal compartment to a second end in fluid communication with the fluid channel, and a locking flange extending radially outward from the inner wall, the locking flange being retained between the retaining structure and the wall in a locking position. The seal is disposed between the locking flange and one of the wall or the retaining structure.

A system for preventing over pressure in a flexible tank when connected to a water grid that includes the flexible tank and a control unit. An inlet of the tank is connected to the water grid through the control unit. The control unit includes a closed box, an inlet that is connected to the water grid, an outlet that is connected to the inlet of the tank, and a float valve. The user place the flexible tank and set the float so that it will be opened or closed in a certain height of activating water level in the control unit and to place the control unit in a way that the activating water level is at the same level of a desired water level of the flexible tank.

A member that is a single element for controlling flow through an inflow control device, has anisotropic density configured to move the member relative to the inflow control device such that the inflow control device allows, fully blocks, or partially blocks flow from a zone to a production string based on a density of a fluid flowing into the inflow control device from the zone.

A valve includes a housing, a first ball, a second ball, and a deflector plate. The housing defines an inner chamber and has an inlet and an outlet providing fluid communication into the inner chamber. A longitudinal axis extends between the inlet and outlet. The first ball is disposed in the inner chamber between the inlet and outlet and rests on a seat extending into the inner chamber. The second ball is disposed in the inner chamber between the first ball and outlet and rests on the first ball. The deflector plate is disposed in the inner chamber and positioned between the inlet and first ball. The first ball, second ball, and deflector plate are aligned so that their centers lie on the longitudinal axis. The deflector plate is configured to deflect gas entering through the inlet to prevent the gas from driving the first and second balls upward.
