Sewer Main – Install, Replace or Repair
The cost to replace a sewer line ranges from $50 to $250 per foot. Most homeowners pay between $50 to $125 per foot.
The price you pay depends on the type of plumbing you already have, the length of the line and its placement on your property. Since repairing almost always involves putting in new equipment, ask your plumber if it makes more sense to do a full replacement.
