How important is horsepower?
Very important, in our opinion. We think high-output spas are the best because you can reduce their flow when required. But don’t get confused by numbers; the real test is flow rating — determined by the amount of water pumped each minute. Turn every jet on and feel for yourself. Without a large powerful motor, you may be required to purchase multiple pumps or reduce the number of jets in your spa. Ask to see a manufacturer's flow chart rating. A simple visual test is viewing the size of the pipes leading into and out of the pump. The larger the pipe size, the higher the flow. Check the amperage rating, too, which is clearly printed on the pump. Higher amperage = higher power.
