ABSTRACT:
A pipe plugging apparatus for use stopping the flow of water or other fluids in a pipe during pipe repair and construction, comprising a hand-held pump, the hand-held pump has a hand activated screw element for moving a piston for pushing water or other fluids within the pump. The hand-held pump has a cylindrical housing with an adjustable pressure relief knob at a first end and a filler intake port and an air bleeder valve positioned at a second end. The cylindrical housing includes a check valve and an aperture at the second end adapted for securing an intrusion tube connector. An intrusion tube with a connector check valve secured on a first end is secured to the hand-operated pump. One or more intrusion tubes may be linked together and provided either empty or fluid pre-filled. A water inflatable balloon is secured to a second end of the intrusion tube by a ribbed connector element.
