Abstract: The modular tubular exhaust system includes a first tubular body, a second tubular body and at least one third tubular body connecting to form, a fully assembled configuration, a vertically arranged exhaust pipe. The first, the second, and the third tubular bodies each have a tubular body first end and a tubular body second end where the first ends and second ends are configured to mate with each other to form the vertically arranged exhaust pipe. The system further includes tabs that extend radially outward on opposing sides of the tubular bodies to allow a plurality of fasteners to attach tubular bodies together when arranged in the vertical configuration. The assembled configuration may vary within the spirit and scope of the disclosure, for example, in some embodiments, the system may only have a first and a second tubular section or a first, second, and a plurality of third tubular sections.

Abstract: Apparatus for adding liquid fertilizer to a water line of a sprinkler system includes a mechanical injector device powered by a paddle wheel turned by water flowing through the water line. As the paddle wheel is turned, liquid fertilizer can be advantageously mixed with the irrigation water or other fluid. The fertilizer reservoir can be positioned on the upper portion of the injector apparatus and can include an inlet connection and a button used to hydraulically prime the system. The fertilizer may be fed into the reservoir via tubing from a separately contained fertilizer source. In some embodiments, an inlet nozzle may increase the inlet velocity of the water, thereby permitting the paddle wheel to operate over a greater flow rate range. The tubing or other conduit can be connected to the fertilizer source container via a quick-connect fitting.
