Patent ID: 7878220

Claim:
A pipe plug system comprising: a non-conductive main body member including a substantially cylindrical portion and a tapered portion on an end of the cylindrical portion, the tapered portion defining a radially outwardly directed engagement surface; an end cap portion on an end of the cylindrical portion opposite from the tapered portion adapted to be matingly engaged oriented in an associated, recessed pipe such that the end cap portion is positioned as at least one of a drain, vent, cleanout, fluid or sewer pipe, or their combination; an annular flexible seal member defining an inner hole configured to receive the tapered portion of the main body member, a radially inwardly directed surface configured to slidably engage the radially outwardly directed engagement surface of the tapered portion of the main body member, and a substantially cylindrical outwardly directed surface configured to sealingly engage a substantially cylindrical inner surface of the associated, recessed pipe; and, a conductive, planar locating appliance connected with at least one of the main body member, the seal member, or their combination, the locating appliance being encased in a protective medium, the plane of the locating appliance being oriented radially outwardly relative to the cylindrical portion so as to maximize exposure to an associated conductive material detector when exposed to a signal emanating therefrom when the end cap portion is matingly engaged with the associated, recessed tubing.
