hi everyone.. im new here. I just bought a house and the previous owners left a 1995 hotspring jetsetter. It seems to be working pretty well after we cleaned it up and got it going however it seems like theres a slow leak under the shell. After a few days the water level drops a bit and i notice theres a very small drip coming from underneath the shell of the spa. any idea how i go about fixing something like this. please help me stop wasting water. thanks in advance.

Take a real close look around the drain caps, light lens, and check for hairline shell cracks in the vicinity of the bottom of the light.
