Welcome to our forum.
Coleman must have revamped their neck jets. It was the one thing I dislike about mine. The neck jets are much weaker than all the other jets in the therapy seats. Can you concur with this HotTubMan or SpaHappy? Is their a mod that can be installed on my 480 to fix these weak jets? Heck I just keep em shut off as they provide virtually no therapy at all. Hey rick,The neck jets have changed and are wonderful on the Coleman 471Deluxe spas. I'll ask my service tech if he can think of a replumbing fix for your neck jets. This guy is amazing..a bit odd, but he really knows his stuff. PM me your serial number as that will tell me when your tub was born and will tell us more about the plumbing in the neck jet area. Good to see your still hanging around.Spahappy Also Bigbender, always take the trash talk of a dealer's competitors with a grain of salt. It sounds like you have told him you are very close to getting a Coleman and his reply is the oldest trick in the book. If you talk to this PDC guy again, ask him to specifically state what makes the Coleman line cheap, and also have him compare his products parts and design to prove it.
