Return of the glycol.
Sounds like glycol is leaking out of the jacket in between the inner and outer shells of FV3. How many gallons of glycol does your res hold? You could drill or file a small hole at the very bottom of the outer shell near the weld where the inner and outer come together, too see if a lot of glycol drains out. One of our fermenters has caulk around the manway and over time leaked water and condensation down in the space between. I noticed a small leak when I CIPed, the rapid change in temp forced liquid out a small crack in the vessel weld down near the bottom, so I filed the crack out larger to drain the waste water. That was some very stinky poodle chew I tell you.
For a welder you most likely can find a local welder who works with stainless. Depending on your area.
