Welcome to our forum.
They could drain the water and turn it up on its side and see where it is wet.This is one disadvantage of a full foam tub, you just have to start digging into the foam.
Ok... couple things.First, turns out this happened right after they drained and refilled. Â I don't know if this is coincidence, but I find it interesting at the least.Second, they turned it off and let it leak for a few hours... they believe it stopped. Â Pulled off a couple panels (I was wrong they hadn't done that before) and nothing is wet. Â Do they start digging towards the jet(s) in question?
If the tub leaks down to a certain level than stops, then I'd suspect that anything above the waterline would be suspect- I'd start looking at that level. If it is potentially any number of jets located around the tub, I'd maybe start by carefully probing into the foam with something like a stiff wire- that might save them a lot of aggravation pulling foam unecessairly. Â Personally, if it was me, I'd probably call in a pro- they have techniques to locate leaks more efficiently than us untrained people. Â If you get someone who works on that model spa, they might know of weak point to check first. Plus, I've seen photos of foam removal- it's looks to be a pretty messy job!
