Welcome to our forum.
Hi and thanks for any help. I'm looking at local dealers have plenty in the $10-12,000 range. They sound good. ex. https://www.calderaspas.com/shop/paradise/makenaBut Costco has some that actually sound way better for $7000. What am I missing? What's wrong with the Costco one? It has more features and is less. I know install is not included, but I could pay the local expensive dealer $500 for that...Thanks!
And to clarify on that a bit more you would have to calculate output GPM of the pump (not the motor which is where they measure HP) And head loss for plumbing and then flow capacity a particular jet has.Jet count and HP means absolutely nothing to the feel of the tub. Manufacturers who use these two things are cheating there customers.
