No one knows who invented the fire hydrant because its patent was burned in a fire


Everyone knows about fire hydrants as it is an active fire protection measure. It has a joining point by which firefighters can release the water supply. But the fact about fire hydrants is that no one knows who invented it. Some say that the flood destroyed the patents, some say it lost in dispute, and some say it got scorched in the fire. So far nothing has been proved, and Frederick Graff, Sr., chief engineer of the Philadelphia Water Works is given credit for its invention around 1801. He invented a post- or pillar-type fire hydrant.

The operator attaches a tube to the hydrant and then unlocks a regulator on the hydrants to provide a high water flow. The compression differs according to the area and depends on several factors including the extent and position of the connected water core. The fire hydrant needs to be unfastened by special gears (large wrench with a pentagon-shaped socket) to avoid wastage. The fire hydrants require annual check and care as the warranty varies from one year to ten years.

In countryside areas where municipal water arrangements are not available, dry hydrants are used to supply water for combating fires. A dry hydrant is similar to a water pipe which is unpressurized lastingly installed pipeline near the lake or pond. The hydrant builds are also color-coded; WHITE- Public System Hydrant (EBMUD), YELLOW- Private System Hydrant Connected to a public water main, RED- Special Operation Hydrant not used except for special events, VIOLET –Non-Potable Supply Effluent, pond or lake supply. These colorations are compulsory by the NFPA (National Fire Protection Agency).

Earlier to the discovery of the hydrant, municipal fire skill involved underground water reservoirs and vessel task force. It became easy to put off fire through fire hydrants as it also saves time and energy. But it’s astounding that there is no confirmed record of the person who created such a useful device.
