For the needs of the contractor on the newly built facility of the gas station "Hifa petrol" in the settlement of Lazarevo in Banja Luka, it was necessary to perform a fault test on the installation from the fuel tank to the filling point.
Namely, after putting into operation, a drop in pressure was noticed on that part of the installation from the pump in the tank to the place where the automatic refueling machine is located. The length of the mentioned control route was about 30 meters. 
Since the pressures are very low during the operation of the pump, for a more precise location of the fuel leak, the pressure was raised by the air compressor.
With such conditions where a pressure of about 4.5 bar was reached, the fault location was successfully located.
After the excavation, a leak was found at the marked place and repairs were made.
