I had the same problem, but it turned out the nozzle was adjustable but just very tight. A cannot move it by hand, had to stick something in the nozzle (rubber coated handle of a wrench) to move it. As far as loosening the fitting, their is a tool that has been suggested on this forum somewhere, its an oil filter wrench and it works great for pool fittings, I found it at Homedepot and bought 2.
