This is probably for Artesian dealers. I have wet tested a three pump 46 jet Captiva spa. The seats are run by 2 6bhp (3 continuous I believe) pumps and i really like the power and pressure of the jets. The foot/whirlpool jet is run by a separate 3bhp pump. The 38 jet version has 2 4.8 bhp pumps (2.5 continuous I believe) with no separate pump for the foot/whirlpool jet. How does the power and pressure of the seat jets compare between the two configurations? Do you get the same feel? Or does the 46 jet version out perform the 38 jet version in this regard? Also, from what I have been able to tell, one of the 4.8 pumps runs two of the cornor seats or the foot/whirlpool jet. Is this correct? If one of the 4.8 pumps can be diverted solely to the foot/whirlpool jet, that would be one powerful jet, as that jet is quite powerful in the 3 pump version. Thanks in advance for comments.
