I have an older HT, the Vita Bijou. It's a 1994 model and it needs some new jets. I've done some research and found that in order to remove them, you should turn them counter clock wise until they stop. Then turn 1/4" more and they should pop out. I turned them C-C wise until they stopped, but they didn't want to turn any further. I was a little hesitant about forcing them too much until I posted to the experts here. This is what mine are supposed to look like.
My fear is that they are so old that they might have bonded a little within the housing. I surely don't want to destroy the housing and cause some major leakage, causing an overhaul of the spa. What would you suggest?
