We just purchased a 2020 Dimension One Triad spa. From day one it has been making a very loud gurgling noise on the top right side wall (facing the control panel). The dealer who is very helpful and responsive has told us it is a normal noise and part of the system design. Based on related topics to this issue, on this forum, I am very skeptical of this advice. Does anyone else have this same issue on a brand new hot tub? Has anyone had it fixed or repaired to eliminate or significantly reduce the noise? I am going to insist this be fixed with my dealer but want to get some opinions or advice from this forum before calling him. Thanks!
