How high should the fire hydrant traffic flange be positioned above the ground?

The correct positioning of the fire hydrant traffic flange, which is the portion of the hydrant that sits above ground level, is important for both functionality and safety. A height of approximately 2 inches above the ground is standard practice. This specific elevation ensures that the hydrant is accessible for firefighting needs while also providing enough protection from incidental damage caused by vehicles and other potential hazards.

Having the traffic flange set at this height allows firefighters to easily locate, operate, and connect hoses to the hydrant without obstruction from snow, debris, or other environmental factors. Additionally, this height minimizes the risk of flooding or water pooling around the hydrant, which can impair its functionality.

Setting the traffic flange too low could lead to operability issues, especially during heavy rain or snow, while a height greater than 2 inches might introduce difficulties for firefighters when attempting to operate the hydrant efficiently.
