Fire hydrants are critical components of public health and safety. For this reason, they need to be tested annually to ensure they are in optimal working condition. Report the findings of your fire hydrant flow test on this form. Analyze the flow test readings, such as tower level, size opening, static, coefficient, etc. to make sure the fire department isn’t in for any nasty surprises in the event of an unexpected fire. Inspect other emergency equipment in addition to the fire hydrant.
