Guys,
I have a cornie that has a slow leak somewhere. I filled it Sunday, and in the process of force carbing and checking it, it looses preasure in about 36 hours. This isn't good since I plan to cellar store it until the tapped keg of the same brew kicks {just recently tapped.} I've checked for gas leaking all around the top, but don't see any visible bubbles around any of the seals. Might there be something I should look for??? I did add keg lube to the large lid O-ring.
Thanks in advance.

brew on
Jeff

Try Windex when looking for leaks - somebody else here mentioned using it and I can say it works great. It bubbles up much better than say soapy water and highlights leaks.

And don't forget to check the poppits. That's where I have the most trouble.

Seems liike I need to apply enough pressure for the large o-ring to seal.

If the Windex doesn't work, immerse the whole keg in the bathtub.

A spray bottle with the appropriate mixture of Star San also works well to local leaks on kegs.

I'll second Johns recommendation of checking the poppits. The internal spring gets weak over time and they may not seal properly.

The foam of StarSan is more long-lasting and effective at finding leaks than soapsuds.

You didn't mention the last time you did an o-ring rebuild. You could alway pull each post and hit each o-ring and poppet with a wee bit of keg lube/silicone. I found my leak was the pressure release valve. A bit of Harvey's silcone from HD took care of that.

Also something to think about. Sometimes the lid feet don't apply enough pressure. One way to cheat a soulution is by placing shims under the feet to act as a leg extension. I found this solve the problem with one of my 'trouble lids'.

Cheers,

Peter,

The little rubber feet wear with use. You can buy replacements at Northern Brewer.
