Pride Plumbing came out and provided a cost estimate to 1) trench a ditch from the house to the septic tank to expose and remove the outside main sewer septic drain line; install a new 4-inch PVC sewer drain line (connecting it to the main drain line under the home) along with proper cleanouts and fittings per code; install tracer wire in the ditch along with the new sewer drain line; and seal the septic tank penetration and backfill, tamp, and spread grass seed and straw after the work has been completed; and 2) pulling a toilet, replacing the toilet bowl's wax ring gasket and closet bolts, resetting the toilet, and testing it; and 3) replace the hookups for a washing machine (this includes installing new PEX hot and cold water supply lines, boiler drains, PVC drain, and a ProPlus plastic washer box; tying the water supply and drain lines into their respective water and sewer mains under the home; and insulating the PEX hot and cold water supply lines).
