Foam issues Please Help

[PBRS1844]

To start this off, I have read multiple articles and threads here, as well as, watched every video I can. I have googled everything under the sun and I just can't figure this keg out.

I have my kegerator set 38 degrees. I poured a cup, all foam, poured it out and poured another and tested the temp. It was 40 degrees.

I have had my keg set to 12 psi with 8 feet of beer line. I have purged and changed the psi up and down and still, a full cup of foam. The only time I don't get a full cup of foam is when the keg is refilling with Co2.

There are little to no bubbles in the beer line coming from the keg but when it's not in use for a couple of days, there is an air bubble that builds up.

I have clean everything multiple times between uses. This is my second time kegging and somehow I am baffled.

Any suggestions would help! Thank You!

Everyone's setup is different, but I typically run 6 to 8 PSI. I'm guessing you found some of those website calculators for CO2, flow, line length and size? Also, when you lowered it, did you vent the kegs and give them time to stabilize at the new pressure? It's not an instant thing.

Currently I have a porter, wee heavy, kolsch, and an irish red all running on the same CO2 line and 7 PSI is about perfect for all of them. The tap lines are all about 6 feet long.

When I have run into issues with overcarbing or foaming (especially with overcarbing though), I disconnect the gas line and burp the keg frequently over the course of several days until there's little to no purge when I vent. It's a pain in the butt since you have to wait it out, but when I plug it back in at 8psi it always works out. Good luck! I know how frustrating that can be.

What is the ID of your liquid line? Anything larger than 3/16” at that length and pressure could be your problem. This line length calculator (https://www.kegerators.com/beer-line-calculator/)
has been the most accurate for me and I typically add a few extra feet more than what it recommends. It recommends 14’ of 3/16” tubing at your pressure for a 12 second pour/ pint. I don’t mind a slow pour since I’m not in the business of keeping people’s mugs full.

This would be the line length calculator you want to use.

The 14 ft mentioned above is probably going to get you close.
