I am looking for information on what pumps would be suitable replacements for my Hot Springs Grandee. The pump we're replacing is a 230V, 2speed, 1.65 Wavemaster 7000, ver 3. Piping is 2 inches on both sides, 48FR. I know I can buy the exact pump, but was hoping to save some money for this repair. The person who will be installing is mechanically/electrically adept, for what it's worth. If anyone can give me some insight to suitable brands that would be great. I've looked at a Waterway Executive that seems to meet all the same criteria, but the eBay seller I contacted is pushing me towards the Watkins OEM.
