Don't get me started on residential guys and their "replace everything because I'm on commission attitude.
Get your torch out and FIX the thing. Any dumb wrench monkey can swap out an evap. It takes a degree of skill to repair a problem like that.
Again, don't get me started. If you have a tool that is not capable of doing the job, then GET RID OF THE TOOL! If I had a wrench that wouldn't turn a fitting or a bolt then I'd throw it away.
If your B tank turbo torch doesn't do a good and proper job of heating the materials to allow you to solder or braze them.....
OK, I'll step down off of my soapbox, now.
