We completed an underground utility repair and valve upgrade for a property in San Diego. Our team excavated a service trench to access the existing main line, replacing an outdated setup with a modern, high-performance plumbing assembly. The new installation included high-quality copper piping, brass unions, and durable ball valve for improved shut-off control. We also integrated a brass pressure-reducing valve to regulate water flow and protect the system from surges. This upgrade ensures a reliable and leak-free connection between the main supply and the property’s irrigation lines.
