A water application device (10/100) comprising: a main body (20/110) graspable along a handle portion (22/119) thereof by an operator, the main body (20/110) housing a flow control assembly configured to enable the device (10/100) to execute a control function relative to flow of water through the device (10/100); and an operable member (30/140) pivotally attached to the main body (20/110) to interface with the flow control assembly to alternately provide flow when pivoted to a compressed position and stop flow when pivoted to an extended position, the operable member (30/140) having a length extending substantially parallel to a longitudinal axis of the handle portion (22/119), wherein the operable member (30/140) includes a locking member, the locking member being configured to interface with a locking head disposed at the main body (20/110), wherein the locking member is disposed at a first surface of the operable member (30/140), the first surface facing away from the main body (20/110), wherein the locking member has a locked position and an unlocked position defined by the movement of the locking member relative to the locking head, wherein compression of the operable member (30/140) with the locking member in the locked position transitions the operable member (30/140) alternately between a locked state and an unlocked state with each compression, and wherein the operable member (30/140) remains in the unlocked state when the locking member is in the unlocked position regardless of the compression of the operable member (30/140) and the locking member does not contact the locking head when the locking member is in the unlocked position, characterized in that the operable member (30/140) is pivotally attached to the main body (20/110) at a pivot point that is proximate to an inlet of the main body (20/110), and wherein the locking member is disposed proximate to an opposite end of the operable member (30/140) relative to the pivot point, with the locking member being provided to move substantially perpendicular to the longitudinal axis. a main body (20/110) graspable along a handle portion (22/119) thereof by an operator, the main body (20/110) housing a flow control assembly configured to enable the device (10/100) to execute a control function relative to flow of water through the device (10/100); and an operable member (30/140) pivotally attached to the main body (20/110) to interface with the flow control assembly to alternately provide flow when pivoted to a compressed position and stop flow when pivoted to an extended position, the operable member (30/140) having a length extending substantially parallel to a longitudinal axis of the handle portion (22/119), wherein the operable member (30/140) includes a locking member, the locking member being configured to interface with a locking head disposed at the main body (20/110), wherein the locking member is disposed at a first surface of the operable member (30/140), the first surface facing away from the main body (20/110), wherein the locking member has a locked position and an unlocked position defined by the movement of the locking member relative to the locking head, wherein compression of the operable member (30/140) with the locking member in the locked position transitions the operable member (30/140) alternately between a locked state and an unlocked state with each compression, and wherein the operable member (30/140) remains in the unlocked state when the locking member is in the unlocked position regardless of the compression of the operable member (30/140) and the locking member does not contact the locking head when the locking member is in the unlocked position, characterized in that the operable member (30/140) is pivotally attached to the main body (20/110) at a pivot point that is proximate to an inlet of the main body (20/110), and wherein the locking member is disposed proximate to an opposite end of the operable member (30/140) relative to the pivot point, with the locking member being provided to move substantially perpendicular to the longitudinal axis.
