The unique JetPak plumbing design allows every jet in the spa to run at the same time. This “PowerPlus” concept means that you will have more powerful jets without using a larger pump. There is less plumbing per jet, and less water friction. With this design, Bullfrog Spas are engineered to be more powerful. All conventional spas have diverter valves because they do not have enough power to run all the jets simultaneously. In a Bullfrog Spa, every single person in the spa can enjoy their massage.
