Charlie called me directly and asked for plumbing service for a main line overflowing. Ace Pelizon Plumbing arrived and found clean out that was overflowing. Charlie approved jetting night before. Jetted out main line from 4†clean out near office. Jetted approx 350’ to where I could not push jetter anymore. Sewer cleared around 75’ I ran jetter approx 10 times out to about 350’ and then drained the water tank approx 500 gallons of water down line to flush and make sure it was clear. Not when I showed up I found some paper towels inside clean out. Paper towels do not break up and have the potential to clog drains. No warranty on commercial drains.
