One of the more minor issues I've run into with my short-sale pool is that the eyeballs are frozen in place. I can't move either the eyeball or the ring by hand pressure alone. Is it safe to grab the ring with a pair of channel locks or something similar, or is there something else I should try first? I don't want to take a chance on breaking something off in the wall, so I figured it was wiser to ask before instead of after. :?
