Brulan,
First off, thank you for all you comments and wisdom. It's very generous of you.
I paid $1,100 which included the services of the seller's son in law to transport and hookup the unit and considering we traveled an hour and a half each way in his truck and trailer (for which he refused to accept a dime), and for which he spent the whole day hooking up power and installing GFI breakers and disconnects, I feel like I got a pretty good value. The son in law is a friend and neighbor, hot tub owner, and a licenced contractor with respectable skills. I have him pretty much at my disposal going forward. He's a stand up guy and wants to make sure I have a good outcome here. Without my faith in him, I would not have purchased this unit.
All that said, here's where I've taken a big risk. The tub hasn't been used in approximately 2 years. The tub was purchased new in April of 1999, so it's almost 7 years old. We didn't want to fill it and wait all day to test it before heading back home, so we just loaded it up and hauled it away.
When we fired it up for the first time, we had some leaking at one of the pump seals. Not sure exactly what to call this spot, but it was a hand-tightened PVC pipe connection just to the right of the pump motor. We tightened it up and reduced the leak to a slow drip. We speculated that it may be a gasket that has gotten pretty dry over the two years of inactivity.
I'm planning to call our local spa dealer up to arrange for an inspection. The dealer seems to have a good reputation, but he's not a Jacuzzi reseller, think that makes any difference?
