ABSTRACT:
The present invention is directed toward an apparatus for efficient, durable, reliable, and cost-effective fluid injection. In particular, the present invention provides an unpowered device for automatic fluid injection dictated by pressure differential in the line. More specifically, the present invention provides a device for injecting a degreasing chemical into air relief valves in municipal wastewater systems, which operates off of the differential pressure in the pumped lines resulting from the pump operating cycles.
