The pipe restoration system first comprises a main header having a plurality of header outlets. A pressure generator with abrasives is also provided with the system and is connected to one of the header outlets to receive air pressure therefrom. The pressure generator is further connected to one of piping system's inlets so as to discharge the abrasives therethrough via the air pressure.
