My main line from house to septic tank was backed up. Quality 1st had a person to the house within a couple of hours of my call. I explained the water backup in the basement bathroom to the plumber. We pulled the lid on the septic tank. He quickly determined that the quickest, easiest, and cheapest way to clear the drain pipe was to back-snake it from the input of the septic tank back toward the house. From the call to fixed was a few hours. The whole transaction was smooth.
