Default crud in dip tube?

I've been aquiring the gear to keg my homebrew for a while, and over xmas got everything set up. I had the keg filled with commerical beer just for the first time since I don't have any beer brewing at the moment.

I've got 5ft of 3/16 id beer line and a cobra tap, all stuffed inside the fridge. I need to store the beer at about 15psi to keep it carbonated, which is obviously way too high for serving, so I've been dialing it down to about 2psi or less and cracking the pressure relief before serving. I've still been getting lots of foam, but instead of foaming in the glass (which it is doing a bit), it's mostly big chunks of foam coming out of the tap. Does this mean there's crap in my dip tube? I didn't have a dip tube cleaner so I didn't clean it out, assuming it was clean (dumb).

Other than this the system is great, and once I can afford a tower the cobra will be in the trash, but until then I'd like a beer without having to wait for the head to settle

Thanks for any help,

Isaac

Without assuming anything (and therefore turning up the temp in the fridge), can I safely depressurize the keg and remove the dip tube to clean it out without ruining the beer? It's commercial beer, so presumably it's not as sensitive to a bit of oxygen than homebrew would be.. right?

You'll have no problem depressurizing. You won't be keeping it for weeks and weeks to worry about the oxidization, you've already tapped it.

Most likely it is either A. Ice B. Low pressure C. blockage D. low beer level hah.

By the way, what did you do? Did you sit there pouring two cases of beer into a corny or party tap a pony into it? Either way, you have already introduced oxygen anyhow expecially if you party tapped a commercial keg.

Keep it clean and sanitize. Check the condtion of o-rings on the dip tubes.

Miscommunication - there's a microbrewery around the corner that fills corny kegs for the price of their 20L kegs, minus the deposit. It's like homebrew, but not

Anyways, I guess if I crack open the dip tube, check it for obstruction, replace the poppet o-rings, then put it back together and get the co2 back on quick it won't hurt the beer. It's -definitely- not low beer level, I bet the keg's not even half gone.

I'll let you know how it goes

Thanks,

Isaac

I poured a few more beers last night and turning the reg down to about 2psi helped a lot - I'm getting good pours now. I did notice, however, that after I pour a beer, whatever beer is left in the beer line runs down back into the keg. If I pour another immediately (within seconds) after, it pours perfectly. If I don't pour it immediately, most of the beer has run back down into the keg, and gets foamy as it comes back up the beer line.

Is the beer line supposed to be always filled with beer? I'm going to buy a longer line of beer hose which should help with my serving pressure, but the first glass of foam is going to get annoying...

That is awesome! I am going to need to ask some of the local BPs if they will do that!

Yeah, it's pretty cool. Bring them an empty corny and some cash, and fifteen minutes later they come out with a full, pressurized keg. It's great!

When you change reg pressure, you have to purge the headspace in the keg for it to have any effect. This is most noticible when setting to a lower pressure.

The overall goal is to balance your system so that serving pressure is carbing pressure.
