An apparatus for cleaning and pressure testing tube structures comprising a cleaning fluid supply pump and a pressurization pump alternately in fluid communication with a feed header having a feed header interface engageable to an end of at least one tube structure and a drain header having a drain header interface engageable to an opposing end of the at least one tube structure and an outlet valved so as to be selectively closed or opened depending on mode of operation of the apparatus. The apparatus cleans and pressure tests a tube by engaging a tube between the feed header interface and the drain header interface and maintaining said engagement while sequentially flowing a cleaning fluid through the inner diameter of the hollow tube, pressurizing a static fluid within the hollow tube, and releasing fluid from the tube.
