Title: Orifice protector

Abstract: An orifice protector for use in subterranean fluid dispensing systems defined by at least one conduit for disposing of wastewater. The orifice protector includes a body in the form of partial cylinder having two ends. The partial cylinder is formed a wall of substantially constant thickness having a C-shaped cross section having an outer and an inner surface. A central portion of the wall includes a plurality of openings such as slits extending between the outer and inner surfaces to allow the outward flow of wastewater from orifices existing in the conduit. The slits are situated about parallel to the ends and extending through about a arc length. The wall also has two longitudinal, linear, parallel edges of equal length separated by a slot adapted to receive the conduit. The wall is composed of a material such as abs or pvc so that the two longitudinal edges are deflectable away from each other and biased toward each other to grip an outer surface of the conduit to stabilize the location of the protector relative to the conduit. The body includes stand-off portions integral with the two ends of the wall and consisting essentially of downwardly and inwardly indented portions of the two ends of the wall for maintaining the central portion of the wall spaced from the conduit while preventing the inward migration of the material such as soil, rocks, stones, pebbles or gravel in which the system is buried.
