Abstract
A yard hydrant of the venturi check valve-fluid reservoir type has a manually operable flow diverter valve which will provide full fluid flow through the hydrant to effectively siphon residual fluid from the reservoir without removal of hoses, backflow preventers or the like from the nozzle of the hydrant. The flow diverter valve is located upstream of the fluid discharge nozzle of the hydrant. A tube connects the venturi check valve with the extreme bottom of the reservoir so that all the residual fluid in the reservoir can be removed therefrom.
