Water Line Replacement Cost in Columbus
The short answer
Standard residential water line replacement starts at $4,500 for a typical 3/4-inch line under 100 feet, installed by conventional excavation with normal access. Line size, length, curb-box access, street or right-of-way permits, directional drilling and site conditions change the price. Sidewalk or blacktop cutting and restoration aren't included.
