c02 absoption rate?

[jhnnyschmidt]

Hello, I would like to thank everyone on homebrew talk for your ideas and information has helped me a lot.

I am a proud owner of a new keezer. Oh no not another keezer thread. haha.

I have stumbled through with help from many threads on here I have to thank you all again.

When I hooked it up my co2 tank emptied. I found two leaks, repaired them, and verified the repair by trning the gas to 25 psi turning off the gas, disconnecting the keg, and making sure it holds for 30 minutes.
NO leak cheers.
So next I hooked up the keg and checked after another 30 min. 3 psi drop? I am going to get some tape and bowl the top of the keg and check for leaks tonight. I was wondering though, the beer is carbonating so does the co2 absorb into the beer and would that accont for the lost 3 psi? Or do I surely still have a leak?

The co2 goes into solution, lowering the pressure.

If you fill a keg with beer, and put 12psi on it and turn off the gas...come back an hour later and turn on the gas and you'll hear it fill up again. It'll keep doing that until your liquid volume 'saturates' with CO2 at the given psi. then you're basically equalized at 12psi as long as the temperature stays the same.
If it warms up the keg will want to hold less gas...if it cools down it'll absorb a little more gas.

Honestly if you had a leak you'd lose more than 3psi in pretty short order. YOu can lose 5lbs of CO2 in a few hours due to a damn pinhole leak (been there...done that)
