Claim:
1. A method of cleaning out pipe systems, comprising the steps of: generating pressurized gas into an end of a piping system having pipes to generate a moving air stream in the piping system; intermittently injecting separate spaced apart bursts of abrasive particles into the moving air stream at the end of the piping system, with different cumulative amounts of the intermittent bursts of the abrasive particles that vary based on different piping diameters; cleaning interior wall surfaces of the pipes with the intermittent bursts of the abrasive particles; reducing at least one of burrs or interior lips in the interior wall surfaces of the pipes, with the intermittent bursts of the abrasive particles that have been intermittently injected into the end of the piping system; and removing abrasive particles and debris caused by each one of the separate burst shots of the abrasive particles.
