Default 1/4 vs 3/16 Beer Line?

I built a keezer, I have 2 taps one for sprechers root beer and one for my home brew (currently an ESB).

I picked up (2) 15' lines of 1/4. I'm trying to serve the root beer at around 20psi (what I read) and I get nothing but head, should I have got 3/16 instead?

also, I get a REALLY funky plastic taste in the first pint. whats up with that? how do i fix it?

thanks in advance.

You need 25-30' of line for a root beer. I use 25' and carb it at about 27psi @38F.

Anything less that this and you'll see foam or have flat beer.

Yes, 3/16" ID is preferable. 1/4" drops less than 1psi per foot.

Where did you buy the tubing? Several people have found some brands are way worse than others in the off taste area. In some cases it goes away after time but for the most part, that first 1oz of pour should be tossed.

1/4 inch vinyl only has .65 psi/ft. restriction, which 15 ftx .65= 9.75 of restricton, plus .5 psi for each foot of elavation. This isn't enough restriction
for 20 psi. Maybe try about 9feet of 3/16, which has 2.2psi/ft restriction.That
equals 19.8 psi of restriction, that should get you about right. If its pouring to slow, just cut off 4 to 6 in. segments till you get right balance. Hope this helps. Cheers

This is good advice...but 20psi isn't enough to carbonate root beer to a level that makes it taste like commercial examples. 25-30 is about right.

When I did soda water, I carbed it at about 30-34 PSI at 40*. I needed 35', (THIRTY FIVE FEET) of 3/16" to pour it without knocking all the CO2 out of suspension. I know that's not what the balancing calculators say, but I say those things are BS. They have never worked once for me. I use 10' of 3/16" for my 11 psi beer and 35' of 3/16" for my 34 PSI soda....works great.

Also, 35' of thick walled bev tubing takes up a ton of space, and gives you that plastic flavor. I bought 50' of polyethylene tubing (3/16, thin walled, hard) from McMaster (part no 5181K424, $0.15/ft), coiled 35' of it and bound the coil with electrical tape....takes up very little space.

thanks for this, I ended up buying 100' of 3/16" polyethylene tubing (5181K424) from McMaster for only $0.11/ft!

When I bought it a few years ago, it was like $.15 a foot- you got a better deal that I did, and I thought it was a bargain then!
