Sprinkler valve blowout plate

A blowout plate for cleaning debris out of an inline valve having removable top works, wherein the removable top works have been removed from the inline valve exposing an outflow path in the inline valve and a screw hole pattern for removably connecting the top works, the blowout plate comprising:

• a generally elliptical plate having a stretched first end opposite a stretched second end, an outlet hole defined through the generally elliptical plate and configured to at least partially align with the exposed outflow path, a plurality of apertures defined about an outer perimeter of the generally elliptical plate, a top surface, a bottom surface opposite the top surface, and a substantially uniform thickness formed between the top surface and the bottom surface;
• a means for attaching the generally elliptical plate to the inline valve;
• and
• a means for attaching a drain line to the outlet hole;
• wherein an imaginary horizontal line extends from the stretched first end to the stretched second end to define a horizontal axis of symmetry defining the top surface and the bottom surface;
• wherein the plurality of apertures is arranged into at least three distinct groupings about the perimeter of the bottom surface;
• and
• wherein a first grouping of apertures comprises at least three substantially circular apertures defined in line about the outer perimeter of the generally elliptical plate proximate the stretched first end.
