Abstract
A safety device for use in a suction outlet assembly of a swimming pool, whirlpool, spa or the like is disclosed. More particularly, the outlet assembly has an opening therein in communication with a pump adapted to create sufficient suction for causing fluid flow through the outlet assembly and a cover mounted over the opening without substantially obstructing fluid flow therethrough. The safety device includes an obstructing mechanism for obstructing the opening when the cover is not properly positioned or affixed to the outlet assembly, whereby fluid flow through the outlet assembly is substantially prevented even if the pump is in operation.
