Plumbing is any system that conveys fluids for a wide range of applications.
Hand auger / hand spinner Hand augers are useful for clearing sink and bathtub drains.They are unsuitable for sending through flush toilets, because the wire might damage the bowl; also, flush toilets have relatively large drain pipes in which the narrow snake can be become tangled.
(A 1?4-inch cable, for example, should never be used in a drain with a calibre of more than two inches.) Closet auger / toilet auger The closet auger (named after water closet) feeds a relatively short auger through a hook-shaped length of metal tubing.
The hook shape makes it easier to feed the auger into the toilet.
Since most toilet clogs occur in the trap built into the bowl, the short cable is sufficient to break up or retrieve the greater majority of clogs. Źródło: https://en.wikipedia.org/wiki/Plumber%27s_snake
Water supply and sanitation has been a primary logistical challenge since the dawn of civilization..
Where water resources or infrastructure or sanitation systems are insufficient for the population, people fall prey to disease, dehydration, and in extreme cases, death. Major human settlements could initially develop only where fresh surface water was plentiful, such as near major rivers.
Over the millennia, technology has dramatically increased the distances across which water can be relocated, but the availability of clean and fresh water remains a limiting factor on the size and density of population centers, and is expected to remain so into the foreseeable future.Źródło: https://en.wikipedia.org/wiki/History_of_water_supply_and_sanitation
