Abstract
A valve disabler for use in high pressure pipe cleaning systems. The valve disabler of the present invention serves to disable a single cylinder in a multi-cylinder plunger pump so as to generate pulsatile pressure surges within a hose member. The pulsatile pressure surges cause the distal end of the hose member to move in a serpentine manner, thus allowing the hose member to negotiate down a tortuous path within the pipe without stalling or becoming otherwise impeded.
