Hello,
Bit of a puzzling problem. I have an almost 1 year old Jacuzzi 400 series and most of the FX style jets are not having air mixed in. I swapped a working jet face with another and the problem did not follow the jet face but the plumbing. Even jets in the same seat have a mix of working and non-aerating jets (flow is always there). I have a call into my dealer but I'm curious what people may think what could cause this.
Thanks!
