Last year I bought a new polishes SS expansion tank from PI. It leaks a bit around the bottom of the color. I asked for a replacement, but none were in. Spring is coming and I need a fix. If I pull the tank, can the neck be reattached without causing more problems?
Thank you,
Tom

the SS is easy to weld. You just need a guy who does this kind of work frequently as the weld seam of the neck is a bit tricky to reach with the burner.
I assume the SS tank is V2A steel so you need to have a highter or equal quality weld material, better is higher quality in this case V4A. Also MAG is what I suggest just because more folks are doing it. 
HOWEVER MIG is better for thin sheet metal..
Important is that you get a nice weld seam color no burning spots etc., hence a professional doing it every day..
Also you migth add a spare lit to max the original shape/roundness of the neck
AND worst case you can hard Solder it with silver solder Ag50 or so. This material flows arround <750 Cel so not so hot hence less risk for deformation. BUT it will show per its yellow color.

Why don’t you make PIM fix it for you? It should be their problem, not yours. When you buy a SS tank from a vendor, you have a reasonable expectation that it will be leak free for a considerable length of time.
well David is right..I was more on the "self fix" trip..
also a question of urgency..more , we still have shit weather..

so far no reply from PI. I sent them a photo as well.
As my friend David said, send it back. If you try to weld it, you run the risk of fixing the leak but distorting the lower surface where the cap seals off. Then you get a second leak under pressure. Magic glues done at home will not work.
Send it back. The thing is defective. Let them replace it with one that isn't.
