    I finally got my beer taps setup, I was previously just using a party tap. Pour my first pint and it came out as foam. I have tried dropping the pressure right down to about 8psi but still foam.

    My kegs are higher than the tap, and I notice that air/foam builds up in the tube, might be air coming back up through the tap. Any ideas on what I can try to improve the situation?

    How long is your line? Also what diameter? Longer line and smaller diameter should be sufficient in cutting down the foam.

    It's 4m of 5/16. My party tap had a smaller tube than that. I might try putting that in the line and seeing if it helps.

    Sounds like it should be plenty to sort out the foam.

    I've had that - bubbles forming
    in the line - reducing the pressure is the only fix but it does take a long time to equalize back to your new setting.

    I will keep pouring then :beer1:
    This one is a fizzy lager so that probably doesn't help matters.

    More thin line is a fix - dropping pressure means you're changing the carbonation for the style and it can cause foaming the system should be balanced for the cabonation level, not the other way. Having the kegs higher than the taps means you also need more line to avoid foaming.

    Temp is just as important as pressure.

    10 degrees at 10psi is where mine generally is.

    8mm 5/16 line.

    3/16 line is ideal for short lengths
