What does fireplug mean?
A fireplug is an upright pipe fitted with one or more outlets and a valve, connected to a municipal water main, that provides firefighters with access to pressurized water. The word is used almost exclusively in North America and is now largely superseded by the more common term 'fire hydrant,' though it survives in older texts, regional speech, and colloquial usage. Fireplugs are typically painted vivid colors — often red or yellow — so they can be spotted instantly at an emergency scene, and parking near one is illegal in most jurisdictions because an obstructed hydrant can cost firefighters precious minutes. The word carries a faintly nostalgic, mid-twentieth-century flavor in American writing, evoking images of children playing in summer spray opened from a street hydrant. For readers outside North America, encountering 'fireplug' simply means the familiar street-side fixture known elsewhere as a hydrant.

Before modern hydrants, firefighters dug into wooden water mains and plugged the hole after the fire — the 'plug' they left behind gave us the word fireplug.

Etymology of fireplug
Fireplug combines two transparent English elements: 'fire' (from Old English fȳr) and 'plug' (a stopper, probably of Middle Dutch or Low German origin). The compound arose in nineteenth-century America from the practice, in cities with wooden water mains, of drilling into the log pipes to draw water during fires and then hammering a wooden plug back into the hole — firefighters later knew where these plugs were and attached hoses to them directly. When cast-iron hydrants replaced the wooden mains, the name carried over.
How fireplug is actually used
Fireplug is chiefly an American term and is now somewhat dated or regional; 'fire hydrant' is the standard term in most of the United States. In Britain and much of the English-speaking world, only 'hydrant' or 'fire hydrant' is used.
