Abstract
A three-way wet barrel fire hydrant includes an enlarged intermediate barrel section, which effectively reduces pressure loss in the fire hydrant. The hydrant barrel is formed by an improved sand molding process which requires the mold parting line of the barrel to be selected to coincide with the centerline of the upper nozzle opening. In this manner, a pattern which forms the sand mold may be removed cleanly from the molding sand, thereby eliminating the need of multiple side cores during the casting process.
