Since their inception in the mid-19th century, fire hydrants have saved countless numbers of individuals. Part of this is due to their simple construction. Loosen a cap and water is pushed through firehoses at a high rate of speed and pressure.
The Importance of Testing
The other part is the constant use of a fire hydrant flow test. On a regular basis, hydrants are tested in a fire department’s region to ensure proper water flow and pressure. If either is below standards defined by municipalities and the National Fire Protection Association (NFPA), it might reduce the ability to effectively fight fires.
Thus, the reason for regular tests. Numerous companies, like Hurco Technologies, provide the necessary tools to help departments perform a fire hydrant flow test. Furthermore, within the ever-growing world of technology, tests can be done on multiple hydrants. Using high-powered transmitters, the results are fed to a program that compiles the data for accurate diagnostics.
What is Tested
The major tests are on water flow and pressure. Once the hydrant cap is loosened, the fire department and utility teams examine how many gallons of water are released at certain intervals. In addition, they record the pounds per square inch (psi) of pressure. From these numbers, departments and utility companies can determine if a hydrant is within spec or needs to be examined.
How is it Fixed?
How a hydrant is repaired depends on the problem. Low water flow can mean a clog or leak in the line. The water utility would handle the repair in that case. On the other hand, corrosion in and around the hydrant means the unit needs to be looked at.
No matter what is done, once the repair or replacement is completed the testing process begins again before the hydrant is put back in operation.
