OK well there is no easy way to find a leak in a solid foam spa. One way is to add dye to the water and then remove the panel and look for the discolored foam and then dig out until you find the leak. Another is to get a 24-36" wooden dowel and start poking into foam on the back side each time you pull out the dowel check to see if it is wet, once you find it wet start digging there until you get to the leak. I am VERY familiar with Sundance spas as I have been servicing them for over 12 years and I can tell you if it is in the back side opposite the topside control it is most likely the waterfall that is leaking. I would remove the back panel and dig out the foam up under the water fall and find the water line leading to that and most likely you will find the waterfall leaking at the bottom.
Any luck finding the leak?
