Fire hydrants actually do not have any water in them on an everyday basis. When firefighters tap into a hydrant during a firefighting event, the water is released from a valve in a pipe well below the frost line in climates where the water might otherwise freeze. If you see a fire hydrant spew water from a collision (with a vehicle, for example) in a TV show or a movie, this is just 'poetic license' on the part of the writers/producers/directors/special effects guys; it would not actually happen in 'real life.'

No comments avaliable yet or editing, so I'll add "after use" to my question. Kudos Grandma, yer half way to what I had in mind for the question. Edits are killing us.

The hydrant has a drain valve that opens when the mainvalve is closed so the water runs out. If the hydrant doesn't have a drain valve then it has to be pumped out manually or it will freeze.
