Fire Hydrant Piping Leak

Question asked by ananthars90 on Apr 3, 2020

we have recently commissioned our fire network consisting of fire hydrants and sprinklers. During the commissioning of fire pumps, it was found that pressure is dropping in the fire hydrant underground piping network at a rate of 14 psi per minute. Is this acceptable? what can be the causes of pressure drops? The network has been hydro tested before.

 

Even though there is a drop in pressure, the jockey pump is able to cover the pressure drop. Guys, please advise.
