Pipe cleaning assembly and method of cleaning a piping system using the same

A pipe cleaning assembly, comprising:

• a connection fixture comprising a body defining a cavity, a first aperture in fluid communication with the cavity, a first connection flange extending from and surrounding the first aperture, an opposing second aperture in fluid communication with the cavity and coaxially aligned with the first aperture, a second connection flange extending from and surrounding the second aperture, a first auxiliary aperture in fluid communication with the cavity, and an opposing second auxiliary aperture in fluid communication with the cavity and coaxially aligned with the first auxiliary aperture;
• a rotatable bonnet inserted through the second auxiliary aperture, positioned within the cavity of the body, and accessible from outside the connection fixture, the bonnet including a generally cylindrical wall having an open first end and a second end, an end wall at the second end of the cylindrical wall, and a plurality of openings formed through the cylindrical wall to direct fluid flowing through the connection fixture;
• an actuator mounted to the bonnet and having an actuator shaft that extends through an opening in the end wall of the bonnet;
• and
• a valve plug secured to the actuator shaft and positioned within the bonnet such that the valve plug is movable within the bonnet between a first position, in which the valve plug allows fluid flow through the bonnet, and a second position, in which the valve prevents fluid flow through the bonnet;
• and
• further wherein the plurality of openings include only a first opening having a first axis, an opposing second opening having a second axis coaxially aligned with the first axis of the first opening, and a third opening having a third axis perpendicular to the first axis and the second axis.
