Monitor your bottle pressure

[Silver_Is_Money]

I just shook my pressure gauge equipped test bottle to see if that would build any pressure in it, and it rapidly shot up to 11 PSI, but then liquid began dribbling out of the region just below the gauge, and the pressure soon fell away. This indicates that my problem is a fault with the test bottle, and not with my lager failing to carbonate.

I seal my pressure gauge mount with Permatex silicon gasket sealer and cure it on top of my furnace for 24 hours. So far not leaky gauges.

If you bought the thread adapter from McMaster, it came with a sealing washer. After deburring the 3/16" hole I rubbed the top of the plastic cap across some fine sandpaper on a glass plate to be sure it was flat before mounting the adapter / washer. No leaks on the 2 that I built.
