In most cases, the hot tub manufacturer will be the one to conduct any repairs and replacements, but you may find that they do not have any parts especially for the older models, so make sure it has already been reconditioned by a factory trained service technician. Do not concentrate more on getting a good bargain, but rather on the quality of the used hot tub you are about to buy.
All our used hot tubs are inspected by trained technicians before resold, plus they go through a thorough cleaning and run test to ensure you years of trouble free hot tubbing.
