I just moved into a new home with an inground spa. It has been losing water when I fill it to full capacity. When I let it "leak" all the water it can, it usually stops around the upper part of a jet (see picture). This leads me to believe it is not the jets. I turned all the pumps off and it still loses water (~1"/day) to the point shown. This leads me to believe it's not the plumbing system, per say. I placed a bucket of water out there also (I live in FL) and the spa loses water quicker than the bucket of water evaporates. Can anyone please give me some advice?
