F is for Fire hydrant
A fire hydrant (also known colloquially as a fire plug in the United States or as a johnny pump in New York City, because the firemen of the late 1800s were called Johnnies, is an active fire protection measure, and a source of water provided in most urban, suburban and rural areas with municipal water service to enable firefighters to tap into the municipal water supply to assist in extinguishing a fire.
It has been claimed that Birdsill Holly invented the fire hydrant, but his 1869 design was preceded by many other patents for fire hydrants, and a number of these earlier designs were produced and successfully marketed. Numerous wooden cased fire hydrant designs existed prior to the development of the familiar cast iron hydrant. Although the development of the first above ground hydrant in the USA traces back to Philadelphia in 1803, underground fire hydrants — common in parts of Europe and Asia — have existed since the 1700s.
A hydrant wash-out is an accessible valve in a water supply main which can be opened to run dirty water out of a main following work on the system and replace it with clean water. BRDC - Brecon & Radnor District Council?
