Right, right, I just typed it wrong - you are correct, though! I did run it correctly myself, and came out with 2 PSI at the faucet. Which should be ok, I would hope. We'll see - if I get a glass full of foam, I'll jump online and order new line

The problem with any old PVC tubing is that it taints any beer that sits in it. See this: http://www.homebrewtalk.com/f35/beer-line-tests-solution-plastic-taste-60380-post615400/

I absolutely find the same thing. The first 2oz of beer tastes off.
Note, 2psi at the faucet is going to be a firehose. I know it sounds like low pressure, but you'll get foam.

I'm actually going to order some 1/8" ID high purity tygon tubing from Mcmaster and see if 3-4' is enough to balance. It will be nice to not taste PVC anymore, nor have to coil up 10' of tubing for 5 different faucets.

I'd be very interested in hearing about your results from that experiment, Bobby. Please let us know how you make out with that. Thanks.

I think beverage grade is the key, not just "any" PVC tubing.

Keep in mind that 2 psi is twice as much as 1 psi. Thats a big difference.

I use 3/16" thick wall vinyl tubing from lowes and have no funny taste, and no pressure problems. The thinner tubing is made so crappy that you wont even be able to stretch it. I have 10 ft of thick wall per faucet in my keezer. Before using it I filled a keg with hot water and pumped it through the lines to remove smell and taste. No one that has ever pulled my taps have mentioned tasting vinyl or plastic, and they repeatedly go back for another one. Just my .02

Beerthirty, have you ever taken just 2oz in a taster cup after the kegger sat overnight? It could be that you've always pulled more at once or that your beers are a little more flavorful. Maybe I have defective beverage grade tubing. Maybe kal had a run of bad luck too http://www.homebrewtalk.com/f35/beer-line-tests-solution-plastic-taste-60380/

I also don't get an obvious plastic taste. If I pour two 2oz tasters one after the other, the first one is just "off".
