Alright, I KNOW this is probably one of the most requested help topics around but I'm at my wits end! I've had a Kegerator for decades and have never really had any foam problem that I could not solve, but recently have encountered one. My setup is a Kegerator with a single tower tap. To be clear: I know how to pour a pint I clean my equipment between each keg and sanitize with Star San I have about a 10' length of beer line coiled up in the Kegerator and running up the tower The tower is cooled with a fan inside the Kegerator blowing cool air into the tower void Temp inside the Kegerator is mid-30F - confirmed using a Thermapen checking a glass of water stored in the Kegerator Poured beer temp from the tap is 38F for my pale ale; again checked using a Thermapen CO2 PSI is about 8 psi I change my beer lines regularly and started having this issue shortly after changing lines. I'm using BEVLEX 200, 1/4" ID X 1/2" OD. Recently added a new Taprite T742HP primary double gauge CO2 regulator Recently added a new Perlick Flow Control (Model 650SS) faucet As mentioned this problem actually surface after a line change in the last 90 days or so. In an effort to correct this issue I've updated my regulator and faucet, to no avail! I would really appreciate thoughts on this as I'm NOT a rookie here, but have been unable to solve this. I'm prepared to rip out the beer line that I installed just a short time ago and replace it to ensure this is not the issue!
Probably want to go ahead and move this to the Home Bar forums, theres some really smart folk over there.
8 psi is way too low. You are unbalanced. What do the beer lines look like after they have sat for a while - pockets of CO2 forming in the high spots?
The pockets are CO2 breaking out since your pressure is too low. You really need to be around 12-13 psi depending on the beer at 38. Bring the pressure up and let it sit for a day.
Bingo! 1/4” line only provides 0.85lbs of resistance per foot. Replace it with 7-8’ of 3/16” BevLex (with 3.0lbs of resistance per ft) and turn your cooler down 2*F. Hopefully you kept your old faucet and reg.
Thanks guys, really appreciate the input! I increased my psi as Doug suggested and am now getting a perfect pour! Cheers!
Next line change you should do as @IceAce was suggesting and go back to 3/16” line. No need for 1/4” in a short draw system.
