Abstract: A conduit/piping sump penetration fitting is disclosed. The conduit/piping sump penetration fitting may comprise a bulk head fitting which does not require a plurality of mounting holes to mount the bulk head fitting to a sump wall. Rather, the bulk head fitting has a flange and a threaded portion. Opposed sides of the sump wall may have a rubber gasket through which the threaded portion is fed. A compression flange and compression nut compress the rubber gaskets onto the sump wall so as to form a fluid tight seal between the bulk head fitting and the sump wall. The threaded portion may have an internal beveled surface at its distal end portion which receives an o-ring. A conduit/piping is disposed in the bulk head fitting with the o-ring disposed about the conduit/piping. A second compression nut is threaded onto the threaded portion of the bulk head fitting which pushes the o-ring further down the internal beveled surface.

Abstract: An EVR ventline enclosure is described herein. The EVR ventline enclosure may provide a substantially sealed lower end portion to mitigate damage of the EVR System from fire or heat. The EVR ventline enclosure may encapsulate a line tapped out of the ventline routed to the EVR System. The EVR ventline enclosure may also encapsulate the canister of the EVR System. In this manner, the entire EVR System is protected from fire damage via the EVR ventline enclosure. The EVR ventline enclosure may be mounted to the ventline and not to the EVR System.

Abstract: A soil excavating apparatus is disclosed for use in combination with a cleaning/vacuuming machine having at least one high pressure fluid supply in the vacuum line. The apparatus includes a spray head secured to the vacuum line first end, and disposed substantially thereabout. The spray head is in fluid communication with the pressurized fluid supply. A plurality of inboard spray nozzles are disposed substantially thereabout. The spray head is in fluid communication with the pressurized fluid supply. A plurality of inboard spray nozzles are removably secured to the spray head and extend therefrom. The spray nozzles are angularly oriented to direct the pressurized fluid towards a center line of the vacuum line.
