Water service line replacement means replacing the buried pipe that carries drinking water from the municipal main to a building. In Canada the utility usually owns the part from the main to the property line or curb stop and the owner owns the rest. Common reasons are lead or galvanized pipe, leaks, freezing and low flow; the new line is usually copper, polyethylene or PEX, laid in a trench or pulled in trenchlessly.
