A standard cleanout installation for sewer, storm, and roof drainage lines. The assembly incorporates an eight-inch cast-iron frame and cover set within a four-thousand psi concrete collar measuring six inches thick and thirty-two inches in diameter. The cleanout pipe includes a screw-on cap and a five-inch minimum vertical clearance to the cover. Below grade, the piping utilizes standard forty-five-degree bends and wye fittings installed over compacted backfill, undisturbed earth, or compacted select material as shown on the plans.
