The article presents different aspects of application of copper pipes in water supply system, which have importance on properly work of installation and people health safety. The article analyses the water flow velocity criteria and their influence on the operation of the installation. It is particularly dangerous for copper pipes to exceed the permissible water flow velocity, as this results in corrosive processes. It is also not recommended that the flow velocity be too low, as it affects the development of biofilm and multiplication of bacteria.
