Pro Plumbers

"lead hung on a string to show the vertical line," early 14c., from Old French *plombe, plomee "sounding lead," and directly from Late Latin *plumba, originally plural of Latin plumbum "lead (the metal), lead ball; pipe; pencil," a word of unknown origin, related to Greek molybdos "lead" (dialectal bolimos) and perhaps from an extinct Mediterranean language, perhaps Iberian.
Plumbing reached its early apex in ancient Rome, which saw the introduction of expansive systems of aqueducts, tile wastewater removal, and widespread use of lead pipes. With the Fall of Rome both water supply and sanitation stagnated—or regressed—for well over 1,000 years. Improvement was very slow, with little effective progress made until the growth of modern densely populated cities in the 1800s. During this period, public health authorities began pressing for better waste disposal systems to be installed, to prevent or control epidemics of disease. Earlier, the waste disposal system had merely consisted of collecting waste and dumping it on the ground or into a river. Eventually the development of separate, underground water and sewage systems eliminated open sewage ditches and cesspools.

Hello, long story. Toilet line stopped up two years ago. A company used high pressure water to clean line. Didnt work. Came back a second time with a plummer. Spouse was told that the line had collapsed, filled with rocks or tiles. Plummer then disconnected that line put in a second line, punched a hole in my tank, fed the new line in that hole. Now two years later, each heavy rain brings a strong sewer smell into the house. Found out later that there were no rocks or tiles in original line, only a large calcium build up over 25 years that had clogged the original line. I do not know if when the new line was put in, the old line was closed properly or if either line was or should be vented? I would like the original line reconnected and the newer line just removed. I plan then to repair the hole in septic tank where the new line entered with tar or concete. I need someone to fix my smelly home.
When a person has a blockage in their sewage system they often try to fix it themselves by adding an acid or a base such as Drano in an attempt to dissolve or dislodge the problem. These chemicals can get into the plumbers eyes [14]when the sewage is splashed during the repair. The plumbers skin during the repair does come into contact with the sewage water.[15] The owner of the toilet might not report to the plumber they have already tried Drano a highly caustic base .
