My power to my pool pump is not working. In the garage I usually connect a plug/power line to a garage outlet. This power line runs to the pool Theplug usually has a grounding plug adapter...the one that has the little metal thing on the bottom. I misplaced it this winter, so I plugged the cord in WITHOUT the grounding adapter and no power to pump. Is it likely the missing grounding adapter thing is the reaon I am getting no power. The outlet itself in the garage has powerb as I tested it and it works fine. Only other possibly is the pool outlet itself is damaged or somehow disconnected. , but I put in a new outlet last summer there. Anyways, I am not an electrical whiz. Any comments welcomed. The missing adapter seems like the obvious possiblity. I assume it needs this to be grounded correctly. I did not do the work, previous owner did it himself.
