Why should serve lines include a "gooseneck" in their design?

Including a "gooseneck" in serve lines is important primarily to accommodate earth movements and temperature changes. The design of a gooseneck allows for some flexibility in the piping system, which is crucial in environments where the ground may shift or settle over time. Temperature fluctuations can also cause pipes to expand and contract. The gentle curvature of a gooseneck helps to prevent stress on the pipe joints and reduces the risk of cracks or leaks, thereby maintaining the integrity of the water delivery system.

This flexibility is particularly critical in areas with shifting soil or where seasonal temperature variations are significant, as it ensures that the system can absorb these changes without compromising its function. Incorporating a gooseneck ultimately contributes to the longevity and reliability of the plumbing system.
