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 first auxiliary aperture in fluid communication with the cavity and coaxially aligned with the first aperture, a third connection flange extending from and surrounding the first auxiliary aperture, a second aperture in fluid communication with the cavity, a second connection flange extending from and surrounding the second aperture, an opposing second auxiliary aperture in fluid communication with the cavity and coaxially aligned with the second aperture, and a fourth connection flange extending from and surrounding the second auxiliary aperture;
• a bonnet inserted through the second auxiliary aperture and positioned within the cavity of the body, the bonnet including a generally cylindrical wall having an open first end and a second end, a valve seat at the first end of the cylindrical wall, 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;
• wherein the bonnet includes a plurality of flow openings formed through the cylindrical wall, the bonnet being rotatable within the second auxiliary aperture between a first position, a second position, and a third position to thereby selectively 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 is spaced apart from the valve seat and at least partially disposed within the open end of the bonnet to allow fluid flow through the bonnet, and a second position, in which the valve plug is in contact with the valve seat and prevents fluid flow through the bonnet.
