 Drain (plumbing)

A drain is the primary vessel or conduit for unwanted water or waste liquids to be flumed away, either to a more useful area, funnelled into a receptacle, or run into sewers or stormwater mains as waste discharge to be released or processed.Drain design and installation parameters are engineered to ensure drain functionality for its intended purpose, allowing for variances in volume, matter to be conveyed and maintenance requirements.
