Kegging and Bottling / Re: CO2 regulator issue
« on: February 19, 2011, 07:08:47 AM »
OK, so remember that new CO2 regulator that was supposed to arrive yesterday?  Well, I'm a dope:

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rt=nc&nma=true&item=200575910892&si=vJZauTEjCN0lrzDH6eUQTCCd30U%253D&viewitem=&sspagename=ADME%3AB%3ABOC%3AUS%3A1123

How the hell do I connect that to my tank?

Edit: OK, so looks like it's actually a secondary regulator and it needs to be connected to a primary one first, right?  OK, time to try again.

I ended up ordering a regulator rebuild kit, but no luck.  I'm going to be trying to a brand new CO2 regulator next (should be in today).  All this got me thinking whether or not there could be an issue with the CO2 tank itself.  Maybe it can't get a tight enough seal?  just throwing that out there.  Really hoping the new regulator just puts the issue to rest.

Edit: Also worth noting that I purchased some new gaskets as well so if there is an issue with the seal, I don't think that's it.

My brother had a spare regulator so I hooked the tank up to it, but have the same issue.  It's definitely still leaking and the high pressure gauge is still at 0.  Is there something wrong with the tank?  Doesn't make much sense to me.  The fact that there's a leak in this regulator isn't a total surprise since my brother thought there might be one, but I don't understand why the high pressure gauge would still be at 0.

Nah, mine definitely needs one.  I accidentally hooked up a tank to it without one once and couldn't figure out why there was gas shooting out of it.  ;)  I just can't win when it comes to kegging.

If you turn the pressure up higher, the leaks will be easier to spot.  Spray something on that will form bubbles easily (star san, soapy water, etc...).  Spray anywhere there is a connection.  It could even be the valves that you are turning off.

A likely cause is the connection between tank and regulator.  Make sure you have the right type of gasket/seal/o-ring for your setup, and use a new one if you can.  I don't like the O-rings that are captured in a brass ring that screw in to the tank, but that may just be me.

Start at 30 psi and work your way up to about 50 or so.  If it will hold at 50, it darn well better hold at 10.

It's funny that you mention the washer since I was a bit suspect of the ones I'm using.  I got a pack of them from Airgas when I went to swap out my CO2 tank and wasn't sure if they were right.  There were actually two different sized ones in the pack and I wasn't really sure which one to use or both.  I may try and get some from a homebrew store and see if that makes a difference.

Kegging and Bottling / CO2 regulator issue
« on: February 08, 2011, 09:28:33 AM »
I seem to have a leak in my CO2 regulator and am looking for advice.  After noticing that my high pressure gauge was at 0 psi the other day, I weighed the CO2 tank to make sure it was empty and then swapped it out.  I hooked up the new tank and found the psi was still at 0.  The other interesting thing I noticed was that I could now turn my low pressure gauge higher than I previously could.  For some reason, I could never get the needle past 25 psi, but now could go as high as the gauge would go.  I don't know if that means there was always an issue with the regulator (it's a Chudnow FWIW), but wanted to throw that out there.  So, because of all this strangeness, I decided to check for a leak in the regulator.  I turned on the CO2 tank, turned off pressure to the kegs, turned up the pressure to about 10 psi and then turned off pressure at the tank.  Sure enough, the low pressure gauge was back down to 0 psi after a few hours.  I followed the advice here and checked out the diaphragm, but everything looks OK as far as I can tell.  I've also sprayed all the connections and gauges and turned on the gas, but didn't see any bubbles.  I'm just about ready to toss this regulator and get a new one unless anyone has any other ideas.  Is there anything else I can try?

Yeast and Fermentation / No airlock activity in yeast starter
« on: June 13, 2010, 12:09:06 PM »
I made my first yeast starter yesterday pout of 1/2 cup DME and a pint of water.  It's been about 24 hours and I'm seeing very little airlock activity and a good chunk of yeast has already settled to the bottom.  I had checked on it at about 9 hours in and again around 19 hours in and there was little activity either time.  Is it possible it completely fermented already and I just missed it?  I was hoping to brew today, but am now wondering what I should do.  I'm not brewing a particularly big beer, should be around 1.054, so I probably could have got away without making a starter in the first place.  Would it be OK if pitched my starter?  If not, should I just give it more time or should I add more wort to it?

If your regulator is reading 450 psi, you're either nearly out of CO2, the tank is extremely cold (about 24°F), or the gauge is defective.


If your tank is on the hump in the back of a mini-fridge, it's sitting right up against the cooling element, so it will be very cold.  My high pressure gauge usually reads about 450 - 500, even when full.

It is and I noticed it's quite cool back there.

I checked my readings last night after turning off the gas and disconnecting the kegs and it was at 14 psi.  I let it site overnight and it was down to 12 psi.  I turned on the gas to see if it would increase and it didn't.  I then let all the pressure out through the blowoff valve and then turned the gas back on.  This time it went up to 15 psi.  I don't get it.  Maybe my regulator's flaky. 

If I do have a leak in the tubing, submerging it probably shouldn't be too hard.  I know I'm not supposed to put the regulator itself underwater so maybe just get it to where it connects with the tubing and leave all the dials above water?  Do I leave the gas on the entire time?  How quickly would I see a leak?

I'm probably just being super-paranoid at this point, especially since I just put the tank on the bathroom scale to weigh it.  The tare weight was 3.5 kg which comes out to about 7.7 lbs and the weight on the scale was a little over 12.  Pretty much exactly where I want it to be with a full-ish tank.  I really should just stop worrying about it at this point, but I've wasted so much money on CO2 and want to be absolutely sure I'm leak-free.

The tank pressure depends *only* on temperature, as long as there's some liquid CO2 left. Which is the case until the tank is about 90% empty. If your regulator is reading 450 psi, you're either nearly out of CO2, the tank is extremely cold (about 24°F), or the gauge is defective.

Disconnect everything except the regulator, let it sit for a couple hours, and see what the gauge reads. Regardless, if you're running out of CO2 in a week you have to have a leak somewhere. (Assuming you have a 2.5 lb or larger tank.)

Thanks.  Let me give you some more back story on the issue and see what you think.  I had actually left the CO2 on and connected to a keg for about 9 hours.  Before doing this, it was at room temp and the internal pressure was at 700 psi.  After sitting in the fridge all day, it dropped to just over 500 psi.  I took it out wanting to see what would happen if I left it at room temperature again, but also turned off the gas in an effort to test a leak in my tubing.  Overnight, the internal pressure remained the same as well as the serving pressure.  I turned the gas back on and the internal pressure immediately jumped back up to 700 psi while the serving pressure remained at 14.  The way I see it, my tubing is OK.  That's when I put it back in the fridge, hooked it up to the keg for a half-hour and then turned the gas off.  When I got home, the serving pressure was still 14 psi, but the internal was down to 450.

With all that in mind and the fact that this is brand new 5 lb CO2 tank that's only been connected to a possibly leaking keg for 10 hours total, is it likely I've already used up 90% of it?  I'm going to go disconnect my keg and leave the gas on and see what happens.  Should I also turn the gas off at the regulator so it doesn't make it's way into the tubing?

Edit:  I just turned the gas back on and my serving pressure immediately jumped up to 17 psi.  I don't know why it would be that high.  I didn't have the locking nut twisted tight so maybe that's it.  Don't know if this means anything at all, but FYI.

I just checked and my serving pressure is still at 14 psi.  I turned on the gas at the regulator and it immediately went into the keg and the serving pressure dropped to about 13 psi.  The keg is full and as you pointed out, the beer might absorb the CO2.  The way I see it, I didn't learn anything from this experiment other than there's no leak between the regulator and the CO2 tank. 

In regards to the internal pressure, it sounds like that's all dependent on the temperature of the CO2 tank as well as it's tare weight.  Is that accurate?  I ask because I'm still trying to make sense of why it would have dropped with my original tank when I got a leak.  The tank was normally at about 550 psi and as soon as I hooked up another keg, it dropped to about 450 overnight and then further down later in the week before finally hitting 0 when the tank was empty.  I got another tank, thought I found my leak so I hooked it up and it immediately went to about 450 again for the better part of the week before hitting 0 when the keg was empty.  Now I'm on my third tank and it's around 450 again so I'm really paranoid here.  Does anyone know the science behind it all and explain why I've seen these particular readings?

Kegging and Bottling / Testing for a CO2 leak
« on: April 16, 2010, 06:16:12 PM »
I've had some trouble finding a CO2 leak in my system lately and am trying to test everything out to make sure I've found it.  My first question is about my internal pressure.  I've heard from a lot of sources that internal pressure doesn't matter, but I've noticed that it's been below the "Order CO2" line on my regulator when I've had a leak.  Right now, it's in the fridge and around 450 psi.  Yesterday, it was around 500 psi, but has been in and out of the fridge since then.  Assuming that my internal pressure is OK, what I've done is I've hooked my my regulator to a keg and then turned off the CO2 at the tank and at the regulator.  I've heard that if I leave it overnight and the serving pressure remains the same (it's currently at 14 psi), it's likely I don't have a leak.  I just want a second opinion.  Does that sound right?  I've already sprayed everything with soapy water and cannot find a leak so I'm wondering if there's anything else I can do.  I appreciate the help.  Thanks.
