I googeld. For quick fill of hot tub on 2nd floor?

I googled more. https://www.nrdc.org/bio/pierre-delforge/little-known-power-circulator-pumps#:~:text=Circulator%20pumps%20move%20hot%20water,water%2C%20time%2C%20and%20money.

 

A plumbing guy at Home depot told me shark bit connectors are not code compliant behind walls (what ever that means?). Per him I need to use plumb clamp/ring ($100 for clamp tool). 

Per google, it is good.
