Patent ID: 7336190

Claim:
A device for the early detection and advanced warning that waste is backing up in a waste pipe line comprising: a tubular body member having an open lower portion, a central hollow core extending axially there through, and a closed upper portion, said open lower portion dimensionally sized and configured to be removably yet sealably fitted and fixed into the waste pipe line, and said closed upper portion being provided with a vent; switching means fixedly secured on said upper closed portion and extending from said upper closed portion into said hollow core so that it is surrounded by and housed within said tubular body member; alarm issuing means installed in a remote location distanced away from the installation location of said tubular body but positioned for easy access and viewing; and communications means connecting said switching means to said alarm issuing means so that when the switching means responds to the rise of liquid waste inside said tubular body member as a result of waste backup in the waste pipe line, it closes a circuit and sends a signal along said communication means to said alarm issuing means, to generate an alarm and provide a window of opportunity to clear up the waste back up.
