Vacuum leak detection

Could you pressurize the system, maybe to a high enough pressure so that the leaks would become more audible?

Any stop-leak you put in the system will be on the low pressure side, and would probably lift off the section surface as the vacuum intensifies.--NBC

    Thought about that . . .

    But we really don't have any substantial compressed air capability around the building; I do wonder if a modest compressor would be able to keep pace with the leaks, though. I suppose it's worth a try. I was wondering if the stop-leak would be throwing money away.

    vacuum leak patching

    ISTR someone here saying they had used epoxy putty, which under vacuum was pulled towards the pinhole.

    Peppermint oil (while the system is running under pressure) might help with finding the leaks.

    Jim you use the boiler to make the pressure

    you adjust the pressure troll up and pressurize it like you are going to blow down the boiler.
    Cost is what you spend , value is what you get.

    Great idea!

    I wonder if I could use almond extract. With the epoxy putty, how was it applied?
