What size lines, temp, pressure, etc.

I think I am just too lazy to look for all this. I just want to know what size line do I need for my liquid. Also, at fridge temp, my beer is still foaming, and I have over 10' of line, and I'm pretty sure I changed that over to the smaller diameter. WTF? What should my IPA be carbed to at say 40 degrees temp, and how much line??

I need to buy some line and connectors for my 2.5 Gallon fire extinguisher keg and want to buy the right stuff the first time.

There's good information to be found here: Crockett Brewing Keg System Balancing

I did find a good Excel spreadsheet with info on it, but I need to find out what my line diameter is before I can try it out. Also need to check temp with thermometer. I want to get it working right before I invite more people to use the tap. Last time I was lucky I managed to get the Centennial Blonde flowing just right.

It's a fun game at first, but eventually you'll get it worked out. For me, 10' lines at between 36-39 degrees with the regulator set at around 10psi. Since I'm not home, I can't check for sure.

The only beer I've have foaming issues with right now is one that I overcarbed.

I just need now to find out what size line I should have. I'm ready to order the fittings to the new keg, but not sure what size I need.

3/16" ID

This gives you (theoretically) ~2.7-2.6 psi of resistance per foot. I have 10 foot lines, so theoretically I should be able to serve at 25psi and have it come out with no foam. I've been serving at 15-18 psi (dunno what temp, I'd guess around 38) with no issue and next to no foam.

Oh, and I used the highly recommended line from mcmaster carr, part number 5181K42. Its CHEAP (7.50 for 50 feet) and gives no off flavor that I can detect.

Alright, so I've got 3/16"ID x 5.5ft lines, push at 10psi, with a temp of 34F. And, like McKBrew, the only beer that's been a foamy mess is the one keg that was overcarbed.

I've found my problem. I had swapped hoses on my kegerator. The larger diameter line is now on my IPA. I thought I had installed the second smaller diameter hose already, but apparently not. I did find the bag that had my new hose and barb adapter though, so I can put it on tonight. Last night was spent rinsing the bottles and gettign kitchen cleaned up for the wife. Yes, I know my priorities.

Got my smaller line on last night. IPA is now flowing properly. Ah, life is good again. Also raised the temp up a bit, from where I had it crash cooling my latest beers.
