I called Roto Rooter, the plumber tech guy Gary D. from the Detroit Farmington area who came out and showed me the main line was clogged due to roots. He put in his camera, pushing through all the way to the city main, about 60ft. From the house to about 30 ft is a 4 inch line then expands to a 6 inch line, inside that 6 inch line was the issue. Most pipes are 4 inch to a 6 inch. Common snake cutters are 4 inch dia. Some cutters expand to 6 inches but roots balls could jam it and be stuck in the 6 inch line. So the best thing before spending thousands of dollars on a new line was to Hydrojet the roots, a powerful 4000psi jet sprayer. He cleared about 95% of the roots that was there for the last 40 years. A great job. Oh, reading other reviews I recorded a 55 second video. copy this link: vimeo(.)com/38809225 Just remove ( )
