ABSTRACT:
Missing drain covers used in connection with swimming pools, spas and/or other applications expose humans and animals to discharge ports in the drains that can develop near vacuums which eviscerate, entrap the body and entangle hair. A drain cover is disclosed that releases an elastomeric plug in the neighborhood of the drain upon removal of the drain cover. The plug becomes entrained in the discharge flow and eventually plugs up the smaller diameter discharge port eliminating vacuum hazards by checking all discharge flow and pressure.
