    Screw for Waterways 640-1800 Drain Cover

    Hey gang. Somehow, my bottom drain cover screws fell out and I cannot locate them. There are 4 screw holes on the cover but according to the manuals I found, it appears only 2 screws are used to secure the cover? I looked at the 2nd drain (I have 2 at bottom) and only 2 are present there but...
