Just as the title suggest, when we turn on our hot tub and the blower, the water is being pushed up and over the sides of the hot tub. This is a new build and the builder has been back out to see if he can figure out the issue. So far, he's removed the the eyeballs and orifices and he flushed all of the jets to ensure nothing was clogging anything up and all looked good. We've also turned up the RPMs on the pump while the spa was on. It was originally at 1500 RPM and so we turned it up to 3k RPMs but no change.

The spa is 11x7 with 6 jets (a little larger than most). This is an all Pentair system with a 2HP blower. If we don't turn on the blower, we don't get any "bubble".

I've read that the blower could be oversized however the builder is telling me that is the standard size blower that he uses on spas smaller than ours and they are not seeing the same issue.

He's called in another guy that he works closely with to see if he can help diagnose what's going on, but thought I'd check on here to see if anyone had any other ideas/suggestions.

Appreciate the insight in advance.
