Just opened our inground pool and took the winterizing plugs off the return lines. I need to adjust the eyeballs but they are stuck on the ring they fit into... I guess because we didn't take the eyeballs off the rings when we closed. Anyone know of a way we can loosen the eyeballs? If not, is it okay to just not screw them into the return line fittings all the way so to be able to adjust them to point the correct way?
