These replacement kits come with a retrofit split-union (see photos below), in addition to the standard unions, to reduce the amount of plumbing changes needed.
See photos for comparison of old types to the new types. Note that Spa-Quip used to use "Nominal" Horsepower ratings, so the 'Named' HP was not accurate at all. Pumps labelled 3HP might actually only be 2HP motors, and so on.
