Exploring the installation location
In solving the problem of uncontrolled leakage of water on the hydrant network, we were addressed by the representatives of the Association of condominium owners Ranko Shipka 78 B.
Since the documentation and cadastre of underground installations were not available to them, it was necessary to locate the position of the pipeline direction.
Locating the fault on the hydrant installation
The location was performed with a detector of installations, cables and metal pipes and precisely marked the found route of water installations.
After the excavation of the installation, water leakage was observed at the entrance of the installation to the facility at the position near the water meter shaft. 
Further works determined a leak on both parts of the hydrant network. Parts of the water supply network lead to the entrances to the adjacent entrances, and whose hydrant network is supplied from the same water meter.
A fault was found in the business premises of the building by the method of correlation and listening to the pipeline route with an acoustic sound detector - geophone.
Further testing and research located the potential location of the second fault in the second part of the hydrant installation. This completed the work of researching losses on the hydrant installation of the ZEV.
