I need to add a drain line for a toilet and a water line for a sink in a building next to the main house, about 10-15 feet away from a laundry room which has a water and drain line (hopefully can just tap into that). The line will be going outside and will have to be underground and go through concrete. Looking for a rough estimate (I understand this does not reflect actual estimate until on site evaluation done). Posts that do not include a rough estimate will be ignored. Thanks in advance.
