ABSTRACT:
A water valve assembly includes a valve body having defined therein (1) a first channel, and (2) a first threaded portion. The water valve assembly also includes a first stop attached to the valve body and a second stop attached to the valve body, the second stop being positioned relative to the first stop such that a recess is defined therebetween. The water valve assembly further includes an attachment mechanism having a base and an arm attached to the base. The attachment mechanism has defined therein (1) a second channel, and (2) a second threaded portion. The arm includes a tab, and the arm is positionable in a first lowered position relative to the base when the tab is located outside of the recess. In addition, the arm is positionable in a second lowered position relative to the base when the tab is located within the recess. Furthermore, the tab contacts the first stop so as to move the arm relative to the base when the arm is moved from the first lowered position to the second lowered position.
