Abstract: A tank tee unit is formed from a plurality of standard pvc pipes secured together only by a suitable glue. It includes a main pipe of heavy wall pvc sandwiched between and glued to two heavy wall pvc pipes extending perpendicularly therefrom which are in turn each glued to a standard smaller diameter pvc pipe that passes entirely through the main pipe to form an extremely strong joint. This provides a unit in the form of a cross with outlets on opposite sides of the main pipe and with thick wall branch lines that can be tapped for other side connections. One side outlet can be plugged to provide a strictly tee unit.
Abstract: A yard hydrant includes a head section with a nozzle, a standpipe and valve housing in traditional hydrant relationship that is constructed and assembled into an integral unit which cannot be disassembled. An operating rod with valve means reciprocates in the standpipe and a valve housing in a well known manner. The rod extends through an enlarged opening formed in the head section for which there is provided a novel two piece gland unit with one piece being a packing gland nut for seal engagement with the operating rod in a well known manner and the other piece being a concentrically larger nut that is removably mounted in said opening in a watertight relationship thereto and in pressing engagement with the packing gland nut. Removal of the gland unit permits the operating rod and any attached components to be quickly and easily withdrawn from the integral unit through the opening in the head section for servicing or repairs.
Abstract: A yard hydrant includes a discharge nozzle above ground level connected to other vertically reciprocal working parts in the ground below the frost line. A cylindrical water reservoir unit, disposed below the frost line around said working parts, includes a diaphragm assembly removably attached to such working parts for reciprocation therewith, and a deformable diaphragm on said assembly provides a water storage area. Residual water in the hydrant when it is turned off is collected in the storage area and returned to the hydrant for discharge through the nozzle when the hydrant is turned on. The working parts are removable from the diaphragm assembly for servicing and repairs.
