From an earlier post - do a search on "rotary jets"
- Wow, what a difference this has made. Â On our '05 Vista (and most other HS tubs I'd guess) you can get OEM replacement rotary jets for all the "Precision Jets". Â These are the little jets that can get "itchy" after a while - the rotaries change the whole feel of the tub. Â I think there were 18 on the Vista, including the knee, wrist, and neck jets all around. Â I found 6 on Ebay, and ordered the rest thru my dealer. Â He'd never changed them so I just experimented at water change time, and found you twist off the bezel and the Precision nozzle comes right out, then use a small screwdriver to pop out the nylon bushing that holds the nozzle. The rotary then drops right in. Â Put a small dab of silicone caulk on the bezel before you twist it back on or it will vibrate itself loose. Â Dealer gave me "inventor's discount" since he didn't know about this - I told him he should have these as a standard aftermarket item (actually I emailed HS that they should put these in every tub). Â This is not hard to do - you are not disconnecting any plumbing.
You should also get rotaries for the larger directional hydromassage jets - especially the 2 in the lounge footwell. AMAZING. These just screw in/out. Â Have fun!
Hope this helps - Buckee
