Pride Plumbing came out and provided a cost estimate to perform the following work: 1) dig down from the septic tank to the house (approximately 10-foot) to expose a section of sewer line that has roots; 2) remove and replace the sewer line with new 4-inch PVC piping and fittings along with installing a new PVC outside clean out; 3) test the new piping for leaks and working order; 4) backfill the area we dug out; and 5) supply and install two septic tank risers, lids, and safety inserts - using the tank mastic to set the risers to the tanks.
