ABSTRACT:
A sewage pipe alarm system includes a portable case seated exterior of the existing pipe. The system further includes a mechanism for detecting a blockage of fluid flow within the existing pipe by determining whether an internal water level within the existing pipe exceeds a threshold water level within the existing pipe. The system further includes a mechanism for notifying a user about the blockage of the existing pipe and a power supply source housed within the case. Such a power supply source is electrically coupled to the detecting mechanism and the notifying mechanism respectively.
