Softub 300. Bought new in 2009. I have replaced the skin (liner) on the tub, the power pack has the original hunter green cover. I have had the seals and gaskets in the power pack replaced 2-3 times. Just recently I have had to add water to it at least once a week. So something is leaking in the power pack again, I assume. Every time I take the power pack to get repaired it costs me around $300. It does not have a light or a seat since I replaced the liner. I just replaced the two spinner jets and it has a new filter. I do have a few chemicals.
