Default CO2 is leaking...need help

So i posted last week on the dropping pressure of my CO2 tank and we all thought it was just due to the fact it was being stored in a freezer.

Well now my 10 lb tank is completely empty. I didnt even fully distribute 2 cornies of beer.

I figured the only culprit for leaking for have to be the lines or the manifold. If the cornies were leaking, they would spray beer, am i correct?

Besides soapy water (which never seems to work for me) what else do you all use to test for leaks?

Any other spots I should leak check?

TIA

Check EVERY connection EVERYWHERE!! If you run by HD or Lowes there are gas leak detection solutions that work very well. Soap has always found mine, but make sure you check the pressure relief valves on the cornies, the beer in and out (sometimes you have a bad connector) any where that a hose is attached, the regulator itself, the connection to the tank and the stem of the CO2 tank valve.

May want to pressure up to 30-40 psi to ensure all gaskets seat properly, then blow down to desired pressure.

Just a shot in the dark, but do you have your nylon washers in place - little white ones



I've seen several people overlook them

A corny leak will only spray beer if the leak is somewhere on the beer out side; under the post, between the post and the connector, between the connector and hose/line. If it's on the gas side or in the lid, or in the pressure relief, it will just leak gas. You can check these by turning the keg upsidedown and sitting it on a paper towel. NOW beer would come out.

I think I've forgotten them. [Haven't set everything up yet - this weekend]. What size nylon washers are they, and are they available at Home Depot, etc?

It took me a while to track down my leak - it was a bad seal on my pressure-release valve on a keg. Drained the tank rather quickly too - I basically had to dump star-san on every connection (it bubbles - easy to spot). I checked that valve about 4 times before I got it to leak on command...

I picked mine up at Northern. I had a TINY leak and those corrected it.

I had a small leak on my sanyo setup and suspected, but could find it.

One day I decided to charge a keg in the sanyo (usually I do that downstairs in my keezer). WHen I cranked the pressure up to 35 PSI, that's when I heard a hissing and quickly found it.

If there's a leak and the pressure is low...not likely to make itself known. Crank up the PSI for a few minutes and see if it gives itself away.

Are "Flare washers" the same as "Beveled washers"? Anyone?

I'm really hoping to put everything together this weekend, and would really prefer to avoid to order such a little part online.
