i have had my hot tub for a year and when it is not leaking it is great. It has been leaking for two months and the company that manufactures the spa is less than helpful and other spa repair co. refuse to work on it because it has a hard shell and is hard to access .  I have changed out all the jets and gaskets . Had it on its side . dug all of the insulation out and still can't find where it is leaking from.Now I am stuck with a great little hot tub that just doesn't work :(
