When a fire hydrant is opened, it should be:

• A. Opened fully
• B. Just opened enough to have flow
• C. Opened halfway
• D. Regulated to flow required

Answer: (A)

Opening a fire hydrant fully is the best practice because it ensures maximum discharge and pressure at the outlet. Partially opening the hydrant restricts flow, lowers the available water supply, and can lead to insufficient pressure for firefighting or flushing tasks. Hydrants are designed to deliver their rated flow when opened fully, so doing so provides the necessary volume and velocity to meet demand. The other options describe reducing or regulating flow, which compromises the supply and isn’t how hydrants are intended to be used.
