Abstract
A system for cleaning of piping system using turbulent flow is provided by providing an input of a fixed flow rate of compressed air and a fixed flow rate of cleaning fluid. The fixed fluid flow is provided by either using an electric pump which may be controlled to do so or by restricting the air outlet of an air operated pump such that only a given amount of fluid will be delivered regardless of the pressure of the system into which the fluid is being delivered.
