Do they still make wet barrel fire hydrants?
Wet barrel fire hydrants like Graff’s still exist today, though their design means that they are only used in warmer climates. Areas subject to the ground freezing in winter use dry-barrel hydrants.
Do dry-barrel hydrants freeze?
Other times, a dry-barrel hydrant may freeze because an unusually cold winter could move the frost line deeper in the ground and cause problems with the water main, potentially damaging the valves in the process. This is why during the winter, you will often see crews out testing the hydrants to make sure there aren’t any freezing problems.
Who invented the fire hydrant?
In 1801, Frederick Graff, Sr. is generally credited with inventing the fire hydrant that resembles the fire hydrants we know today. Known as the "post" or "pillar" design, these hydrants gave firefighters access to the water through a hose/faucet outlet.
