I need to adjust return inlets in my pool in order for a pool cleaner to work properly. This is 10 yrs old pool, and nobody probobly touched those inlets for all these years - so it is really hard now to loosen the lock rings holding the eyeballs in the inlets. In fact, I couldn't do it by hand.
They are plastic lock rings ~2.5 or 3 inches in diameter. Of course, they are under water. I don't think it would be a good idea to use metal pliers on them, and anyway I don't have pliers that big. Does anyone know if there's some tool (plastic?) that could help me to unscrew these rings, and where to get it? Or maybe there is some kind of lubricant or something that I can apply to the rings, and which is safe to use in pool?
Thanks!
