The line is it spurting a stream of water

So my question is can anyone help idk how but silver solder brazing isn’t working for me and I can’t get the welder guy to answer

I'd scuff and clean the surface really well, use a good liquid flux and reflow your solder

If you need a quick fix Bolverk if you can get hold of some milliput or a two pack epoxy clay that stuff go's inert when it sets, it will seal it from the outside so no contact with the mash, will put you on until you can get it welded.
Milliput is the best.
Good luck

I've had to do this a couple of times and it works.

[Salt Must Flow]

Same thing recently happened to me. Found a leak, silver soldered it and did cleanup. Here's a link. Not much to show other than a before/after pic. Silver soldering is easy, but stainless is a little trickier. The area should be sanded or abraded well. It needs to be clean and fluxed. I orient the part so that the repair is facing up so that the solder doesn't run off. I use Harris Stay-Clean because that's what most recommend. Heat the area up as well as the surrounding area otherwise the heat wicks away. Flux again to keep it clean. Keep heating. Keep testing with solder and suddenly the solder melts. With practice you'll start to get pretty good at it.
