THANKS FOR THE REPLY DAN!!! I got home last night and kept looking at them, messing around and the knob slipped a little. I pulled, it came off, screwed the threaded assembly to the tub, put the knob back on and it works like a charm. My next dilemna is the VersaSage jet on my tub has spit out all of it's bearings. I've tried to get it back together, no luck. My lovely dealer says, sure no problem! only 80bucks for a new one........I'm looking online to try and find one, any ideas on where to buy or who might make that particular jet would be so much help!!!
