    had a big leaker last year & couldnt locate it with the insulated lines.
    i borrowed a thermographic camera from a plumber buddy & was lucky
    enough to find a cracked 90 in a liq. line within an hour.

    You said this was a Low Temp rack.... how many systems are Gas Defrost?

    I'll give it a try next time I'm in that situation.

    If you are evacuating a system that held refrigerant, I will GUARANTEE you that your detector will alert on the exhaust. Even at 0 PSIG, what, exactly, do you think is contained within the piping?? Fruit juice?

    I will GUARANTEE you, if you read the reply correctly, you could have saved yourself from sounding obnoxious.

    This is an open forum....please refrain from child like behavior...and keep your fruit juice to yourself.

    As you said, this is an open forum.

    I try to pop foolish ideas like that when I see them. This is to prevent someone who isn't knowledgable from coming along and accepting them as being accurate.

    I apologize for offending you.

    I regularly leak check Walmart stores and have had many hard to find leaks. Even so, the toughest still only took 3 days repairs included. I use an Inficon Dtek Select detector. It has no problem finding even the smallest leaks with 404a. The worst was under a set of frozen bunkers. Had to separate and move them to get it fixed. Good luck.

    Phase Loss has a thread where he has posted some very nice pics of what those cameras can do for us as a leak finder. Now to convince the company to buy one.
