So I was sitting in the hot tub last night and the top whirlpool jet outer ring/ dial/bezel/whatever you call it, blew out and hit me in the back. It was a delightful experience! I examined it to see if anything was broken but it doesn't appear to be. Are these supposed to turn and lock into place somehow? Can't find any info on the web. It is not just a ring. It also has a clear plastic (male end) that fits into the opening. It just doesn't seem like it is locked in when you turn it anymore. Any ideas? Thanks!
