SUPPORT CR on PATREON:
It should be noted that this video isn’t meant to be a comprehensive guide to fire hydrants. There are tons of variations of hydrants, especially when you start looking outside the US. In this video, we look mainly at US hydrants and fire systems. Enjoy!
Other note: The colors of hydrants expressed in this video are in regards to the color of the body. The color of the cap can also be used to indicate flow rate per NFPA standards.
Fire hydrants are all around us. These above ground pipe fittings can supply flows upwards of 1500 gallons per minute to save lives and put out fires across the world. We all know what fire hydrants do but how exactly do they work?
Called fireplugs, fire pumps, johnny pumps, fire hydrants, these life-saving pipe fitting shave been around since 1801. Their designs vary by country of origin, but they usually have a connection point to hook up a fire hose and a nut or bolt to turn that will start the water
