Had a gentlemen come to troubleshoot water leak and changed the direction of all the Return Inlet Eyes. My pool is old 80's and I can't find a blow out to see how to re-adjust. Looks like a fitted shell screwed to the pool wall, the gentlemen told me to slightly unscrew the four screws, then put the screwdriver in the eye and seat then turn to adjust. I did this but can't find the point to which the screwdriver is seated into something in the eye, just goes all the way down the throat of the pipe. Any thoughts!
