why is it that periodically through the act of pouring a pitcher of beer i can see a brief section of foam pour then clear beer then foam etc....

Because your lines have a hot spot, Would be nice to know the length of run and how are you cooling the lines.

It could also be a pressure issue.

IT IS ONE OF 4 PERLICK SINGLE KEG DISPENSERS,

ALL BEER AND GAS LINES ARE CONTAINED WITHIN THE KEGERATOR

5'-3/16" BEER LINE
5'-5/16" GAS LINE
LABATTS BLUE
37.2 DEGREES
9 PSI CO2

Bump your pressure up to about 12-14 psi

THAT MAKES MUCH MORE FOAM AT 12-14 PSI

Is your tower getting any cold air to it?

Labatts Blue is about a 2.5 vol. beer. At 37 F beer temperature, should require 13 PSIG. Have you conducted a pressure leak test? Leaks can cause dispensing issues. At 9 PSIG eventually the beer will pour fine once you have degassed it enough. At this time the beer will be flat.

How would one go about performing a "pressure leak test"? Do you test the whole system, including the keg? Could the problem lie within the mechanics of the keg itself? I've have seen this problem a lot lately and an increase in pressure seems to help in most cases, but I'm curious to know if I'm fixing the problem or just covering it up by increasing the pressure.

Yea I dont know how to test for it but by increasing the pressure you could fix the problem you'd just be flying through C02

quote:To leak test the entire system, leave all valves open with the keg couplers in on position. Be certain that no one is dispensing while testing. Turn the gas cylinder wheel off and observe the high pressure gauge (indicates pressure in cylinder). If the needle begins to drop, you have a leak somewhere in the system.

To isolate, turn all the valves off and raise the handles on the keg couplers turning beer off but leave them in the keg well. Turn the wheel back on pressurizinfg system and then again turn off noting the needle on the high side gauge. If it drops, your leak is right at the regulator since the shut off below it is in the off position.

If it does not drop, your leak is downstream. Open the regulator shut off and repeat turning wheel on and off. Continue this process until you isolate where the leak may be. Using leak detector soap or other detection device, find and repair. Be aware that the leak could reside at the coupler or even the keg itself.

Hey about the foam... This is something that just fixed my problem a while back. When I put on the hosing from the coupler it was tight but the black washer looking thing inside it was out a little and air was getting in that way, and plus there was air getting in at the faucet as well because it was tight enough. You might want to try to make sure you have no leaks in those two spots
