The system of static pressure tests of fire hydrants had become much easier with the innovation of new computer software’s and other sophisticated systems. Fire hydrants pressure testing is very crucial in the designing and planning of automatic sprinkler systems. With the evolution of modern system software’s supreme accuracy and precision is maintained throughout the scenario of fire hydrant tests.
Fire hydrants should be tested regularly so as to assure their capacity to deliver a pressure and flow rate that is quite necessary for firefighting procedures. Normal or reliable pressure of water is considered to be maintained at 20psi for efficient fire fights and also to avoid any contamination of water resources through back flow.
If this pressure fails to be maintained or is below the safe level, then fire fighting systems may get jeopardized or compromised very badly. As you know, even the large engines for fire fights are incapable to carry an amount of 2000 gallons. Usually the fire fighters will relay on the nearest water sources as their aid for additional need of water. The fire hoses will route water to the pump which is then again made to gush through the hoses directed to the fire rage. It is very important to maintain the static pressure of fire hydrants and hence the static pressure tests too.
We can’t just go for a second thought in case of these tests as otherwise this can evoke many problems. If the pressure drop is smaller, one could expect greater amount of water availability during fire fighting measures.
Once we consider the instruments for fire hydrant pressure test, we have to study on the hydrant flow testing apparatus, with car pressure gauge pitot pressure monitor, telog test recorder etc. A flow test mainly includes two fire hydrants one is the residual or test hydrant and another is the flow hydrant. Here the cap which covers the hydrant is opened and is connected to one equipped with a pressure monitoring system. Now, appears the static pressure which is considered to be the water pressure at the hydration outlet.
