Can anyone point me to some national (U.S.) organization of "Plumbers" wherein I might find definitions of their terms? I am particularly interested in the definitions of sewer line main (line) branch (lines). According to the company that cleaned my "sewer line" the "main" and "branch" lines are different and that I only paid to have my "sewer line" cleaned the first time therefore the guarantee was ONLY on the sewer line. When I called them out after three weeks (guarantee 6 months) the blockage was now in the "main" line so they charged me again. McM
