If you are worried about the drain because it may pull you down, correctly designed pools have more than one drain, tied together. That way, if something gets drawn into one drain, the pump will just draw from the other drain instead. That way it cannot pull hard enough at one drain to hold you down. The designers thought this out for safety reasons. This does assume that the pool was designed by someone knowledgeable.
