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.
