I have an Image Paradise spa. The center spinning pieces of the small jets are popping out. How do I replace these and where can I get parts? Does the entire jet need to be replaced or just a clip that holds the spinning piece in? " title="Rolling Eyes" />

normally the center part (the part that you turn to adjust) can be removed by rotating it counter clockwise. They frequently are hard to turn and require a tool to remove them. I use a really large plier designed to remove automotive oil filters. The you typically buy the whole new jet and replace it.
