That is not true at all, and you know that. Where did you pull that 28% number out of? And that is also not true about the spas not being tested. I have been to the factory, and all of the spas are tested before the leave they plant. Any other lies you want to tell us.
The industry standard on leaks is 28-30% and the last I heard was the dealers receive 85$ to wet test the tubs on their own. I am sure some of the tubs are ok, I am just not a fan, from fixing many of them I would not choose an Arctic myself. Any sales person from most arctic dealers scare customers with the leak/removable skirt story. Every dealer has the same script and a fact is that I have personally repaired many of their tubs.
