How can I determine the horsepower?

When determining the horsepower of your Waterway Spa Pump there is two key identifiers that will be needed. The two identification keys are Voltage and Amp rating. These two pieces of information will decipher the actual horsepower of the spa pump.

Even though your spa pump says it is 5BHP doesn’t mean that it is a 5 horsepower pump. OEM manufacturers often use the peak rating to market a strong pump. Hot Tubs are designed and engineered to work with a specific GPM of water flowing through the plumbing and increasing this GPM can actually damage your spa and spa pump. The list provided below will help to determine the actual horsepower of your Waterway Executive Spa Pump.
