Can't control this foam.

[michaelsmith269]

So I have a kegerator and it's pouring beer at about 37degrees I have a 61/2 ft beer line. I bought a bud light 1/4 keg and more than half of the time it was pouring like crap. The when I got to about 1/4 of the keg left it was pouring perfect at 7psi. Bought another to test it again and it was all crap this time. I want to fix the problem before I get a good beer. Any recommendations.

If you have a tower you might want to try a tower cooler. That helped me a lot. I still had some foaming with a tower cooler and decided to increase my beer line to 10 feet and that fixed the foaming issue.

If you keep the bud light at 7psi it will eventually run flat. You need to be close to 12psi to keep the carbonation.

Try about 10' to 15' of beer line.

I try that out. Let you all know how it goes

One obvious problem here is that your serving pressure didn't match your carbonation level. Bud Light is carbed to 2.7 vol, which requires 13 psi serving pressure at 37°. Less than that and the CO2 will want to come out of solution forming pockets of gas in the lines, which will cause the first beer to be foam if there's more than a few min wait between pours.

Longer lines will slow the pour down which should help if the pour was too fast. At under 38° your line length should be good up to about 2.7 vol though. I'd still suggest 10' lines though, as they're more forgiving and capable of serving a wider variety of beer temps and carb levels.
