Abstract
A drainage disk is disclosed for placement around a drain opening in a floor of the type comprising a mortar layer, and a novel drain construction is provided wherein the drainage disk is positioned between the floor pan and the mortar which is laid over the floor pan. The drainage disk comprises a disk-shaped piece of relatively thin sheet material having a central opening therein. A plurality of elongate valleys are formed in the disk, with the valleys extending radially outwardly from the central opening in the disk piece. In the drain construction, the disk overlies the flange portion of the drain receptor to prevent the weep channels in the drain receptor from becoming clogged or blocked with extraneous matter. The valleys in the disk provide drainage from the pan to the weep channels in the drain receptor.
