I have a pot with two welded ports that I am using as a HLT. Bottom port has a three piece valve. When putting the valve on I wanted the lever on top and probably tightened it too much. The end result was a small hairline crack by the weld. When I used the pot some small drops of water were coming out of the crack. Nothing crazy and probably not worth worrying about but wondering if there is some kind of product I can put on the outside to seal the crack. It looks like it is cracked where the bottom of the pot is welded on. I should also add it's an "economy" pot so maybe not even worth it as it still seems to do the job.
