Default Accuflex Bev-Seal Ultra - length of line?

Hello,
I bought the Accuflex Bev-Seal line.
I read as much as I can find on this and answer vary greatly
On the group by thread there are guys using any where from 12-20 feet in length.

I have just made/kegged my first batch ever.

Details here if anyone is bored -
http://www.homebrewtalk.com/f36/1st-...s-biab-291598/

I cut it the line to 20' and was able to get it connected to keg/tail piece...that is a job.

My beer has been on gas 9 days now....12/12.5 psi at 36-37 degrees.
The middle of my keg is about 23" below my shank.

My pour now is OK, but missing some head unless I drop the glass down several inches..and then head is about 1/2" is that normal?
I know I should wait a week before I do much tweaking since the beer is still carbing.

Are their calculators for this exact line to show my how long it should be based on my setup?
How do I know, other than keep cutting it back, if line is to long?
I guess slow and no foam is better than all foam...


thanks Kevin

I'd wait until the beer is fully carbed before making it shorter. I use 20ft line, 13psi at 38-40 degrees and i'm happy with the pour. You can always cut later, but you can't add it back.

I'm using 10' at 12psi and 52F, 30" vertical between middle of keg and tap. It's coming out ok, it could be better, but i'm not about to trim the Accuflex Bev-Seal and re-attach. Maybe if i got a heatgun i would be more amicable to adjustments : )

i'm assuming we're all talking about 3/16".

I'm using around 16ish feet in my keezer. Around 10 psi and 38 degrees. I might be able to shorten it a foot or two, but overall i'm happy with it. A little of a slow pour, but it was such a pain to get the hose on that I'm not going to screw with it. Like you said, if i want a larger head, i'll just move the glass from the faucet a little.

Yes 3/16" line.

Thanks for the replies so far.
Kevin

I have a 6' line that is a bit fast and a 10' line that is a bit slow... for my 12 psi, 8' is prob spot on.

How fortunate. I was searching for this very same answer and it looks like you just posted this question today.

Well it looks like that variation has expanded even more. We're now at 6-20 ft in this thread

That sounds like a pretty good pour to me, but I'm not sure where you're dropping it from. Several inches from the tap, or the drip tray?

It would be good to hear some real science behind the balancing of the lines with the Bev-Seal Ultra. If someone does have a calculator/spreadsheet, I'd like to see it. I guess the target flow rate would be the first thing to get agreement on, no?

This article gives a formula for calculating if you have the resistance value of the line.

There is this thread discussing it on TheElectricBrewery website, but it looks like it was before the Bev-Seal Ultra was available (again) in 3/16" ID. It provides a few outside sources for calculating line length. Now, if we can just get verification of the line resistance. I put in an email to the company. I'll post back if I hear anything, but if someone else has information that they can provide, please do so.

I'm wondering if a big part of why we are seeing such variation is the lack of accuracy in the gauge used to measure our serving pressure? I know that on my gauge at least, it goes from 0 - 80 or 100 psi, so i'm in the beginning of the range where the gauge is the most inaccurate when i'm trying to dial in 10 or 12 psi. So i wonder how many of us think we are serving at 10 psi and in reality are at 12 or 13 and have to balance our lines based on that, but others have a gauge that reads 2 or 3 psi low and are actually at 8 psi and only need 8-10 feet of line.

Maybe i'll get a more accurate gauge that only reads from 0-20 or something like that.

Edit: Just looked on mcmaster, and the best pressure gauge i could find, had 2% error in the middle of the range, and that gauge (0-30 psi) was 20 bucks. I doubt the gauge that comes on our regulators are that accurate, and also we probably aren't in the mid-range for them at 8-12 psi, so they could be off even more. I bet this has a lot more to do with the variation in line lengths that we are seeing than we give it credit for.
