My pool has some strange looking eyeball jets. They are black and don't have the usual external ring. They are old and worn, so the eyeballs automagically rotate to an orientation that blocks flow which means that more water has to return through the fountains, chilling the pool. Good in summer, bad now. Has anyone seen these before? Do you know who makes them, what they're called and how to get replacements? The thread is larger than the normal 1.5", they measure 1.840" so they're probably considered 1-7/8".
