Thanks PreservedSwine.
I couldn't write back sooner because the site wasn't allowing me to post for some reason.
I don't quite understand what you wrote but we will try replacing that part. Since this sounds like it involves the jets, would this still be applicable if we didn't use the hot tub from January through the beginning of April? We only ran the jets for 30 minutes once a week when we put chemicals in. Now we have gone in it a few times since the beginning of April and used the jets for awhile and there is no leaking. Do you know how I can prove this is the fix since it is not leaking now? Is there a way to get it leaking before we replace that part and then try the same thing after? Why would warmer weather stop the leak if this is the problem?
Also do the sides come off? Just wondering because I can't find anything in the manual about that.
Thanks again!
