should be installed at the low point of the gooseneck. Gooseneck, Lead (pigtail) Leaded goosenecks are short sections of lead pipe (1’ to 2’ long) used during the early 1900s up to World War Two in supplying water to a customer. These lead tubes could be easily bent, and allowed for a flexible connection between rigid service piping. The bent segments of pipe often took the shape of a goose's neck, and are referred to as “ lead goosenecks.” Lead is no longer permitted in new water systems or new building construction. Goosenecks (also referred to as pigtails)Water Transmission and Distribution (Principles and Practices of Water Supply Operations Series), 3rd Edition. By AWWA (American Water Works Association) Pub. Date: 12/28/2003 are in-line components of a water service (i.e. piping, valves, fittings, tubing, and accessories) running from the distribution system water main to a meter or building inlet. The valve used to connect a small-diameter service line to a water main is called a corporation stop (also called a tap, or corp stop). One gooseneck joins the corporation stop to the water service pipe work. A second gooseneck links the supply pipeline to a water meter located outside the building.
