The toilet is one of the basic parts of any residential or commercial plumbing systems. It’s one of those items you know you can’t live without!
Of course, there were centuries when people did live without them—and it was a much less sanitary or comfortable time. The first flushing toilet was invented in 1596 by Sir John Harrington, which included a flush valve and wash-down mechanism—convenient and sanitary. But it wasn’t for almost another 200 years that the flush toilet as we know it was invented, and only in the 19th century did its use become common because of increased city living, where sewer systems made toilets beneficial for hygiene. This was also the period when being a plumber became a professional occupation. You needed skilled individuals to help out whenever something went wrong with a household toilet. Plumbers were important heroes for public health! (And they still are.)
