Just a hint to hopefully save somebody some time. I was trying to figure out how to change the orientation of the elbows coming out of the FS20X7 valve. There were no screws holding them in place and there was nothing in the instructions. They did not easily move with gentle pressure, and I was concerned about damaging them. I couldn't find anything about it in the instructions or through a web search. They are just held on by friction with an o ring in place. They will come off with firmer pressure. Hope this saves somebody some time.
