Patent ID: 8904962

Claim:
A watering system comprising: a watering line which is configured to receive water from a source; a pressure regulator which is configured to regulate a pressure of the water within the watering line; a plurality of nipple drinkers which are operatively associated with the watering line in order to provide water for drinking therefrom; a hollow stand-tube having a free end, the hollow stand-tube configured to hold water therein, the hollow stand-tube being operatively associated with the watering line; and a breather cap assembly associated with the hollow-stand tube, the breather cap assembly comprising: a body having an upper portion, a lower portion, and an aperture which extends through the upper and lower portions of the body, the lower portion being connected to the hollow stand-tube proximate to the free end thereof; a seal having an aperture provided therethrough, the seal being positioned within a portion of the aperture which extends through the lower portion of the body such that the aperture of the seal is in fluid communication with a portion of the aperture which extends through of the upper portion of the body; a cap which surrounds the upper portion of the body and which is secured to the lower portion of the body, the cap being positioned relative to the body to define a passageway between an outer surface of the body and an inner surface of the cap, and wherein the passageway allows for air flow therethrough such that air can flow from outside of the breather cap assembly, between the cap and the body, into and through the portion of the aperture which extends through e-f the upper portion of the body, into and through the aperture of the seal, and into the hollow stand-tube, and vice-versa; and a valve which is positioned within the hollow stand-tube and which is configured to float in the water within the hollow stand-tube, the hollow stand-tube, in conjunction with the valve, providing a visual indication of the water pressure in the watering line at the location of the hollow stand-tube via a height of the water in the hollow stand-tube, the valve further being configured to seal the aperture of the seal in order to minimize the possibility of water escaping out of the hollow stand-tube when the height of the water within the hollow stand-tube rises, thereby further preventing air flow between an outside of the breather cap assembly and the hollow stand-tube.
