Hmm...VERY interesting comment! The filter housing manifold on this spa threads right onto the end of the heater outlet. This manifold is also severely distorted. Perhaps this spa had a major over-heat the last time it was run? Sounds like I'd better keep a close eye on this thing the first time I bring it up to temerature. Thanks again for the feedback.

Thanks for the feedback. I suspected heat...but wow...the water would have to be really hot (boiling?) to distort something like that...or so you would think. The local spa parts guy said "chemical abuse." Is that guy blowing smoke, or can a chemical imbalance really affect plastic like that? As for replacing the jet... I sent the picture to an on-line parts source, and they were able to track down new lock-rings for those jets. I should have them within the next 10 days. One problem fixed...a few more to go. With any luck, I'll be in this hot tub by Labor Day...

I have a hot tub from the late 1980s (don't know the manufacturer). Two of the jets popped out because the mounting rings had become warped/distorted: Questions: 1. What caused these jets to distort so badly? 2. Any suggestions on where to locate a replacement? Some quick searches around the net have turned up nothing, and the local dealer looked at me like I had two heads when I brought this jet to their parts counter.

Thanks once again for everyone's advice. I'll be sure to swap out the breaker before I do anything else.

Would it have been typical for someone to wire a circuit like this 20 years ago and not have some sort of GFCI protection? That seems insane! Thanks for the information guys. Sounds like I'd better steer clear of this thing until I can get that breaker swapped out.

I'm working with a hot tub that was installed around 1988. It's powered from a single non-GFCI 50 amp breaker in my household service panel. There's no GFCI load center/quick disconnect box involved. Here's what the spa controller looks like: This tub hasn't been used for 5+ years. Amazingly, everything seems to work fine. However, I'm concerned as to what ground fault protection it has. Exactly what (if any) protection does that GFCI outlet on the controller provide? If there's a fault with the pump/blower/heater, is that GFCI outlet going to trip...or is that outlet wired independently of the other components? When I press the GFCI "test" button with the pump/heater running, nothing happens. Also, I read this blurb on another website and it has me a bit concerned that the heater circuit has no GFCI protection: I don't want to get near this thing until I understand what ground fault protection I have! Any comments would be appreciated!
