Does a bigger pump mean a better massage?
Many manufacturers talk about the horsepower of their pumps. Horsepower can be measured using a “peak factor” or a “continuous duty” system. The first describes the initial thrust as the pump first engages, but immediately the pump output falls to a lower, continuous horsepower level. When a spa manufacturer claims they have a 6-hp pump, they are describing the “initial thrust” not the horsepower the pump delivers as it runs. Efficient plumbing, better jets, and flow control are more important than horsepower. A lower horsepower pump in a more efficient spa will produce just as much jet power as a higher horsepower pump. And remember, you are looking for a comfortable but strong massage, not for a punishing hot water experience! Consider the GPM rating as a trued measure of effective hydrotherapy not the HP rating that is so often misconstrued by other manufacturers.
