Came out for gurgling noises coming up through the main floor toilet. Arrived and found everything draining normally and no gurgling. Homeowner said she was doing laundry upstairs, and came downstairs to find the main floor powder room gurgling, and then the water in the toilet rose up out of the bowl and started flooding the bathroom. Could not recreate issue. Received approval to pull toilet in powder room and run camera. Located a belly outside of the home right before the septic tank with signs that this is where the blockages had been occurring as this has happened to her more than once. She already had the septic tank pumped a month ago thinking this was the issue and this did not correct the issue. Received approval to repair the sewer line. Dug up the sewer by hand and Repiped the section with a belly in it. Bedded pipe with a gravel foundation and backfilled to top of pipe with sand. Re-camerad the sewer line with the homeowner to show her everything was now flowing correct
