Hi- I inherited someone's hot tub a few years ago (Garden Leisure 8-man, nice tub but a little older), and a crew brought it over and set it in the driveway, where it stayed for three years or so. So the other day we wired it up and filled it. Several diffusers are missing and I was getting ready to order all new ones, but figured it wouldn't hurt to fill it and start it up to see if it worked. At first the pump leaked a bit (which I anticipated). After a bit I kicked on the jets and water was dripping out all over the place, on all sides. So we shut it down and drained it. I'm no tub expert, and I've been reading enough to determine that there could be cracks or bad gaskets throughout. The tub is foam-covered and the jets are not easy to get to, but not impossible. I'm pretty handy and have thought about trying to redo this thing, but I don't know if it's even worth it. My questions are: 1. is there a way to perhaps seal these jets without getting to the underside of each of them? 2. does the missing diffuser have anything to do with a leaky jet? 3. is this tub beyond repair? Thanks for any advice, suggestions, words of wisdom.
