Detroit Plumbing

Before the advent of indoor plumbing and sewage waste management systems, the cry of "Garden l'eau" (pronounced "Gardy-loo" in English) was the proper method for warning passersby before throwing the contents of chamber pots out onto the streets. The "loo" in "Garden l'eau" is now the slang term for a toilet. Since 800 BCE plumbing in some form has been used, and plumbers fix these systems. Presumably, your plumbing needs do not stretch back twenty-nine centuries, no matter how out-of-date your bathroom may seem.
