This spa pump has 2-1/2" intake (which measures about 3-11/16" outside diameter), verify that both your intake is 2-1/2" as some Waterway Executive pumps have 2" intake (which measures about 3" outside diameter). Waterway Executive pumps do not include unions, while your current ones should work we do recommend getting new o-rings and save your self the headache of possible leaks..
The Executive pumps allow you rotate the wetend to 3:00 - 9:00 or 12:00 position. We ship them at 12:00 unless otherwise told.
We suggest that you compare amperage (amp) ratings versus horsepower (hp) when sizing your current pump as many spa manufacturers use a "marketing horsepower" that is often different then the motor truly runs at.
If you have questions reading the information from your pump motor please see our motor label page, or watch our quick video. As always we are here to help if you have a question email or call us.
