I looked at Hot Springs, Jacuzzi, Sundance, Bullfrog (and threw in Viking). I own an old Sundance, but right now, Bullfrog, IMO, is where it's at, and the others are going to have a tough go for the next few years keeping up.LOL, drink much koolaid? I can give you 3-4 reasons the engineering is flawed.

Here's one good reason. And I have asked several questions of BF folks and never gotten any answers either so...... But anyone who says I never provide good reasons I will be slow and precise. As a 30 year plumber water movement has been close to me for a long time.1. Cavitation is an important part of all plumbing. It is designed out as much as possible because it is noisy and it reduces volume pressure. The most common place for cavitation to occur is in the distribution manifolds, all tubs have them to disburse the water. Where are the distribution manifolds on a BF spa? Yes, that's right in the jet pac's next to your ears.As a long time tub owner and repair guy I have looked at and serviced many BF tubs and recently had a chance to soak in a 2017 big BF, loved it. Great tub, not by any means an engineering marvel. Been in tubs that felt better, been in quieter tubs.Want more reasons or should we not? All I was doing is letting our posters know there was BS a float.

Being a P.E. working in the field of fluid dynamics, cavitation occurs at the inlet to the pump, nearest to the impeller, where suction pressure exceeds the fluid vapor pressure. You are being confused with entrapped air within the positive pressure water stream where microscopic air bubbles gather and create noise. It's not possible (fluid dynamics-wise) to cavitate in a positively pressurized fluid pathway.
