According to the formula here (http://hbd.org/clubs/franklin/public...s/balance.html) I need about 11 feet - I think 18 would be a little excessive

But I probably will go with something temporary for now and order replacement lines. I'd go buy the "right" stuff from my LHBS, but they want to bend me over for $1/ft. Methinks not.

No one has an issue with hardware store tubing for the gas lines though, right?

I love the stuff, but hard to get set up. It is 2.5 inches
2-1/2" (2.5")

bend radius, so not too bad.

You will be a lot happier with 3/16. I have 1/4 right now and I will get 3/16 soon. It really sucks have two taps both with 20 feet of line because it takes up way more room than you would think in the fridge.

By the way, I think beer line might have a smoother inner diameter to reduce foaming.

I tried 11 feet and it was no where near close enough. It came out like a firehose. 20 feet does well for me.

Are those threaded fittings or barbed fittings. If threaded...the 3/4 refers to the thread width, nit the ID of the hose that will eventually installed.

Barbed. I did end up finding 1/4" ID braided reinforced vinyl tubing at Home Depot that is apparently (according to the box) specifically for "beverage lines." So hopefully that will do the trick. It only came in 10' lengths though, so we'll see. Either way, it came out to like $.44/foot, so it will hold me until I can order the "right" stuff. Assuming it doesn't work on its own.

Thanks everyone!

Oh and also, I keep my beers at 40 deg and use 10 PSI. So that helps. If I plug those numbers into the formula (L = P - (H * .5) - 1 / R) with a length (L) = 10', pressure (P) = 10 PSI, height to faucet (H) = 2', resistance (R) = .7, I can get the pressure at the faucet (represented in the formula by a constant, 1) as 2. Two PSI at the faucet shouldn't be the end of the world. So I guess I'll keep my fingers crossed

your original formula (assuming standard order of operations) would yield 7.6 ft rather than 11.4

Don't let anyone fool you into buying the super special beer line. Just order PVC or other beverage grade tubing that matches the internal and external diameters of what NB or any other store carries. You'll get the same stuff.
