Pride Plumbing came out and provided a cost estimate to 1) use an excavator to trench a ditch from the house to the town sewer tap to expose and remove the outside main sewer septic drain line; 2) install a new 4-inch PVC sewer drain line (connecting it to the town's sewer tap at the edge of the property and the main drain line underneath the home) along with proper cleanouts and fittings per code; 3) cut the concrete in a garage, dig down to the drain pipe underneath, and replace that drain pipe with new PVC piping and fittings - connecting onto the new drain line in the yard; 4) install tracer wire in the ditch along with the new sewer drain line; and 5) backfill, tamp, and spread grass seed and straw after the work has been inspected and approved by Montgomery County's Inspection Department.
