an installer must have over-tightened the two true union connections seen at the bottom of this picture. They are very large plastic connections. (Smaller of the two is at least 4" diameter so you can easily wrap two hands around it. The larger one has those breakable plastic fins on it.)
I'm no wimp but I cannot unscrew either one to clean the screen inside.
I don't have any tool that's large enough to wrap around either connection nor can I imagine the price of a wrench that's the proper size and, besides- I'm pretty sure these connections were designed so that they're HAND UNDONE. I've tried wrapping connections with a towel, rubber grips etc.
What else is there to try before I go spend money on a huge wrench?
