Assemble the dry well, then use a hammer to knock out all the 1½-inch-diameter drainage holes and one of the 4½-inch ports. Shovel a 6-inch-deep layer of washed, ¾-inch rounded stone into the hole. Set the dry well in the hole and slide the port over the PVC pipe. Center the dry well and fill around it with stone until you reach its top edge.
