Welcome to our forum.
Also, to add to Chas's post, you're still under warranty. Just bring the defective jet to your dealer next time you're in to buy chems, and they will replace it with the new style.
What's the new style for the Tiger rivers? I do have a problem with the nozzles on the foot dome. 2 popped out. 1 doesn't like staying in. Since it's a foot dome jet, I don't care/worry about it. Also. i upgraded my light bulb, didn' I void the warrenty?
New style for the directional and rotary jets no longer have the four prongs for attachment. They are more of a one piece item that screws in. As far as the dome jets, next time you drain, just silicone the small directional jets that have a tendency to pop off. Do you have a 1st quarter 2004 caspian??
I dunno. :-/Purchased in Arpil of 05. how could I tell when it was made?
