Don,
Aqua Jet is a great pump but be aware that if you buy it on Amazon, Aqua Jet may not warrantee it. I ran into this a couple of years ago. At that time, Aqua Jet told me they could not come to agreement with Amazon on a contract and that Amazon was purchasing the pump from other suppliers, which voided their original purchaser warrantee. Not sure if this is still the situation but a call to Aqua Jet might save you some future hassles.
