Fire Flow Testing


Every water distribution system is different and unique depending on construction and geographical locations. The reason that hydrants need testing is to verify if they can produce the correct amount of flow at a certain pressure rating. To meet or exceed these requirements would be in compliance with the N.F.P.A. Standard 291 - Recommended Practice for Fire Flow Testing and Marking of Hydrants. Municipalities and Authorities responsible for fire protection should conduct such testing to confirm their systems capabilities.

   
In the past, it took several people to coordinate the efforts for a hydrant study to achieve usable data, which in turn will provide reliable results. Now, a digital in-line flow hydrant and pressure logger at the residual hydrant is all the equipment required along with a trained operator to perform the opening and closing of the hydrant. After, the data is extracted from the logging equipment; the data can be used to generate reports indicating the systems performance of flow at 20 psi. This in turn will establish the appropriate marking colour for the hydrant.  


Conditions within a system can change with time. The aging of the material, as well as demand fluctuations due to population growth or industrial downsizing will have a major effect on the performance of the system for fire flow capacities. This is why practical hydrant flow performance is essential on a routine basis. Computer models, if not calibrated regularly, may not always yield accurate data. With colour-coded hydrants, any problem areas can be determined and identified allowing for alternative connections in the case of fire fighting.
