    With the possibility of hundreds of places for a leak, you can be sure to be leak free! CO2 leaks can occur at any fitting, the gas source, serving tanks, bottling and keg washing systems and so many more places. How do you know when you've found them all?

    Leaks can occur 24 hours a day/7 days a week. That means a small leak of one-half cubic foot an hour wastes more gas each day than you would use to dispense two kegs of beer. The McDantim Bypass Leak Detector shows you in seconds if you have a leak, gauge how big that leak is, and know when it's fixed. One glance before you start using gas tells you whether you have a leak or not. As leaks are repaired, it serves as your scorecard, letting you know how much of the problem is resolved and if all leaks are fixed.

    The McDantim Bypass Leak Detector is simple and easy to install; it can be used with any Micro Matic or Trimix™ Gas Blender.

    Leak Cost Calculations: At 100+ PSIG inlet the ball will float at 2.8 scfh and max out at 12.7 scfh. Based on a CO2 value of $.30 per pound, even the smallest leak detected by the Bypass Leak Detector can cost over $800 per year.

    NOTE: For use with systems where maximum usage is a flow rate to 600 scfh or 70 lbs. CO2 per hour.


    1. It is highly recommended a coalescing filter be installed between the gas source and the McDantim Bypass Leak Detector.
    2. Install the McDantim Bypass Leak Detector indoors (after the filter) as close to the gas source as possible.
    3. Connect the (filtered) CO2 inlet, barb under pressure gauge.
    4. Connect the CO2 outlet to a gas distributor or similar CO2 distribution method.


    1. Keep handle pointed up to 'Normal Flow' until you are ready to check for leaks.
    2. The ball will rest at the bottom of the scale.


    1. When CO2 is NOT in use, turn the handle down to 'Leak Detect' mode.
    2. If the ball floats, you have a leak.
    3. Turn off all sections to the downstream CO2 gas distributor or similar CO2 distribution method. The ball should drop to the bottom.
    4. Turn one section at a time back on, if the ball floats you have a leak in that section.
    5. Use soapy water to locate your leak in that section.
    6. Repeat this process until all sections are turned back on and the ball no longer floats.
