Had to go old school to find leak

[monkeyman#1]

Was working on a walk-in cooler yesterday that had a leak. Pinpointed the leak to the evap with my D-tek, but couldn't find the exact leak point. Sprayed entire end of evap ( u tubes, TXV, distributor) with super blue bubbles, no bubbles. Reduced pressure from 110 pounds to 35. Again sprayed bubbles, no bubbles. Down to 5 pounds, again no luck
Alright, enough of this. Cranked pressure back up to 110, went to my truck and grabbed my buried halide torch (cant remember the last time I used it), to evap, and bingo, found leak asap! Im thinking that I may start using my torch a little more often.

I wonder how many apprentices even know what you are talking about.

Good for CFC & HCFC only yes or no ?

ive had my boss tell me about them..better than a leak detector he said. Google laughed at me when i tried searching for one in the shopping section

They can have my halide when they pull my cold dead fingers from it.

Or when all my favorite refrigerants are gone.

Does anyone still sell those?

[jpsmith1cm]

I haven't actually used one in a long time.

Less and less CFC/HCFC stuff out there.
