Okay. No groaning is a good thing. Also, that could very well have been the noise. This system is under a lot of pressure especially when turning so if something lets go it can sound like a balloon popping.
All we can do is fix what we find broken and then retest. The frustration comes in (and it gets expensive) when we can't find anything and it still doesn't work. That is when people start guessing at parts or take it to a repair shop. Either way, it is more expensive.
I would just go ahead and repair what you found and retest it.
