I would expect this type of leak to be covered under there 5 year component warranty, but I would ask for clarification or read through the warranty in full...
I know Hot Springs "leak" portion of the warranty states this: "Watkins warrants the Hot Spring spa against leaks caused by defects in manufacturing and workmanship for five years. This warranty specifically covers leaks from the wall fittings, jet fittings, internal plumbing, internal glue joints, drains, hoses, and all bonded parts"
