Abstract
A freeze resistant sanitary hydrant is provided that employs a reservoir for storage of fluid under the frost line or in an area not prone to freezing. To evacuate this reservoir, a means for altering pressure is provided that is able to function in hydrant systems that employ a vacuum breaker.
Claims10
A sanitary hydrant, comprising:
- a standpipe having a first end and a second end;
- a head for delivering fluid interconnected to the first end of the standpipe;
- a fluid reservoir associated with the second end of the standpipe;
- a means for altering pressure positioned within the reservoir and interconnected to the second end of the standpipe, the means for altering pressure comprised of a first end, which is interconnected to the standpipe, and a second end associated with a fluid inlet valve with a throat between the first end and the second end of the means for altering pressure;
- a bypass tube having a first end interconnected to a location adjacent to the first end of the means for altering pressure and a second end interconnected to a bypass valve, the bypass valve also associated with the second end of the means for altering pressure,
- wherein when the bypass valve is opened, fluid flows from the inlet valve, through the bypass tube, through the standpipe, and out the hydrant head;
- and
- wherein when the bypass valve is closed, fluid flows through the means for altering pressure, thereby creating a pressure drop adjacent to the throat that communicates with the reservoir to draw fluid therefrom.

A method of evacuating a sanitary hydrant, comprising:
- providing a standpipe having a first end and a second end;
- providing a head for delivering fluid interconnected to the first end of the standpipe;
- providing a fluid reservoir associated with the second end of the standpipe;
- providing a means for altering pressure positioned within the reservoir and interconnected to the second end of the standpipe, the means for altering pressure comprised of a first end, which is interconnected to the standpipe, and a second end associated with a fluid inlet valve with a throat between the first end and the second end of the means for altering pressure;
- providing a bypass tube having a first end interconnected to a location adjacent to the first end of the means for altering pressure and a second end interconnected to a bypass valve, the bypass valve also associated with the second end of the means for altering pressure, wherein when the bypass valve is opened, fluid flows from the inlet valve, through the bypass tube, through the standpipe, and out the hydrant head;
- and wherein when the bypass valve is closed, fluid flows through the means for altering pressure, thereby creating a pressure drop adjacent to the throat that communicates with the reservoir to draw fluid therefrom;
- initiating fluid flow through the head by actuating a handle associated therewith;
- actuating a bypass button that opens the bypass valve such that fluid is precluded from entering the means for altering pressure;
- actuating the bypass button to close the bypass valve;
- flowing fluid through the means for altering pressure;
- evacuating the reservoir;
- ceasing fluid flow through the hydrant;
- and
- draining fluid into the reservoir.
