Abstract
A method and apparatus for tracing sewer connections with RFID PIT tags consists of using at least one radio frequency identification (RFID) passive integrated transponder (PIT) tag embedded within a protective outer covering, and at least one RFID reader and antenna system to trace the flow of a fluid within a plumbing system, sewer lateral pipe, sanitary or storm sewer system. The RFID PIT tag and protective outer covering are introduced in one point within the plumbing system, sewer lateral pipe, sanitary or storm sewer system, such as by flushing a toilet. Subsequent collection, or detection of the RFID PIT tag at another location within a sewer lateral pipe, sanitary or storm sewer system is used to establish the presence of a hydraulic connection between the introduction and collection or detection points. The method is useful to identify whether a plumbing system or sewer lateral pipe is properly connected to a sewer system without the need to actively observe the presence of a visual tracing aid such as dye.
