Why Replace

Old galvanized lines corrode internally, reducing flow and leaching rust. Lead lines pose serious health risks. Replacing with copper or PE restores pressure and water quality.

Excavation Process

The old line is located, a trench is dug to below the frost line, the new pipe is laid and connected at both ends, then the trench is backfilled and compacted.
