In media when an out of control car runs over a fire hydrant the inevitable result is a geyser of water that instantly adds
both drama and excitement to the scene. In reality the most
likely result is a good deal of front end damage and a bill to repair the broken hydrant, but in a non-trivial amount of cases the car will
wind up as an aquarium. What determines if this trope is Artistic License
or Truth in Television
is the design of the hydrant
. Hydrants known as "wet barrel" bring highly pressurized water all the way up into the part that sticks above ground
. Hydrants known as "dry barrel" keep the vital valve equipment many feet underground, which are then opened via a long shaft.
Any location subject to cold temperatures must
employ dry barrel hydrants to avoid problems with burst pipes
. This combined with the protection against the very calamity that the Hydrant Geyser portrays is why dry barrel hydrants make up the overwhelming majority of installed units in North America. Of course with wet barrel units being acceptable in warm locations such as Southern California, that design makes up the majority seen in media
, hence the popularity of the trope.
This trope is constantly hovering on the border of becoming discredited
or even a dead horse
with spoofs and parodies making up a large number of examples, however it is frequently played straight both in media and Real Life
. Like the exploding car
, this trope maintains a strong grip on the popular psyche causing people to be genuinely surprised
when hydrants are knocked over with little fanfare.
The presence of a Hydrant Geyser can always be Hand Waved
away by saying that any given dry barrel unit was accidentally left pressurized via an open valve.
Often the geyser is preceded by a comical rumbling of the ground as if Hydrant acted as some sort of champagne cork or oil well. This is always wrong as a pressurized hydrant will instantly gush water, not take a few seconds to "get going".
