The plate includes a sump mesh having a sump mesh size of less than approximately 0.1 inches. The filter mounts to the filter aperture edge and includes a sidewall and a plurality of posts mounted to extend up from the sidewall. The sidewall includes a filter mesh having a filter mesh size of less than approximately 0.1 inches. At least a portion of each post extends above the filter aperture edge when the filter is mounted to the filter aperture edge. The cap mounts above the plurality of posts. The plurality of posts and the cap form a conduit sized to allow material that cannot pass through the sump mesh to flow through the conduit.
