Patent ID: 8388760

Claim:
A portable non-disruption of sewer flow root treatment system for the elimination of roots in the sewer system that uses an existing flow of a sewer system to transport an efficient amount of a foaming root chemical needed to treat a desired zone of a pipe, wherein the efficient amount of root chemical is brought to a consistency to travel via route of the existing sewer flow to a location to be treated for the elimination of roots in the sewer system without plugging the pipe and stopping the sewer flow, the portable non-disruption of sewer flow root treatment system comprising: a) an expandable restrictor capable of entering a smaller diameter pipe than that being treated, wherein the expandable restrictor includes a protective braking bag with at least one adjustable strap that controls and varies the expansion size of the expandable restrictor, wherein the expandable restrictor travels under the roots in the pipe then expands but does not fill the entire circumference of the pipe and floats on the existing flow of the sewer system, thereby allowing the flow of the sewer system to travel and only restricts the foam of the root chemical from flowing further downstream of the desired zone that needs treatment, wherein the expandable restrictor is interchangeable with a conventional basic restrictor, attachable to other equipment used in sewers, and is capable of being positioned in a downstream sewer manhole; and b) a root chemical dispenser for dispensing the root chemical into the sewer system; wherein the root chemical dispenser receives a source of water to activate the root chemical to a consistency to travel in the sewer system via sewer flow to the desired zone of the pipe where the expandable restrictor is floatably positioned.
