Invention of Flush Toilet.
Plumbing means a system including both supply and drainage of water. A flush-toilet therefore, means a toilet in which water is used to drain off the human wastes out of the house. This system was introduced in the Indus valley about 2500-3000 years ago but almost disappeared thereafter. It was in 1778 that Joseph Bramah of England restarted the flush-toilet system. It was in 1860's that Sir Thomas Crapper , an English plumber, improved the flush toilet system of Joseph Bramah. He made improvements so that water could automatically stop flowing into the reservoir when it was full.
