    Poor brazing

    I look forward to a day when people learn that a proper braze joint is NOT when you stick a bead of silfoss around the outside of the joint.

    Seriously? 😕 I fixed that one a few weeks ago but forgot to get a pic.

    And then today had this one that was leaking terribly.Name:  548_1484877565152.jpeg

    I'm at a loss for words. This is happening too frequently.

    A good braze should not look like a tumor.

    Looks like that line set has herpes. Don't touch it!

    I'll put this up for shats n giggles. I did this. A 3/4" water line with a 1/4" hole. It was still drizzling water... but it's plugged.





    Every time I go back for something I see that it doesnt leak but still think "what a hack".

    How can you think that's not going to leak then walk away ?
    The primary function of the design engineer is to make things difficult for the fabricator and impossible for the serviceman.

    So I guess I shouldn't tell you that I've had water lines freeze and split. Rather than cut them out and solder in couplings, I've pinched them shut and brazed over the crack!

    Because 15% silver solder is rated in the thousands of psi, and it only has 65 psi on it. Plus, it hasnt leaked in years and the pipe will rot before the fix will.

    it's the best way to do it. stronger than a coupling.

    Not to be weird here, but I thought you weren't supposed to use braze because it would "contaminate" the water supply. Seriously, just asking.
