still all foam

[mikhen]

Installed new line from keg to faucet. All foam. Installed new regulator. Still all foam. Could there be an air leak in the line from the keg to the faucet?? The psi is about 4. Never had trouble till I replaced the line.

You need to tell us a lot more info like...

What size beer line? (length and diameter)
Where'd you get the beer line?
What is the temp of the beer in a glass immediately after you pour one?
What kind of beer?
Where are you located (elevation)?
4 PSI is no where near enough for just about any beer. Most beers need 12-13 PSI to maintain the proper carbonation and pour correctly. Less pressure usually causes foam.
When was the last time you cleaned the tap or the faucet? Did you take the faucet completely apart to clean it?

3/16" hose about 5' long, bought from here or ********
38 degrees

I'm in Eastern Pa
Just cleaned the faucet and whole assembly
Any pressure more than 4 cause alot more foam
Thanx for your help so far

You need to put the pressure at 13 psi, and then we can figure out what the problem is. It will never dispense properly at 4 psi, and will be flat in 24 hours.

Mikhen...like Bonefish and I have said, the pressure MUST be at 13 or you WILL get all foam and your beer will be flat in no time.

That beer comes from the brewery with a certain amount of CO2 or carbonation in it - just like it does in bottles. If you don't keep an equal amount of pressure on the beer, the carbonation will "break out" of solution and the beer will go flat (just like it would if you left the cap off a bottle for a day). The foam you're getting is the carbonation that should be in the beer!

How much pressure you need to keep on the keg depends mostly on the type of beer and actual temp of the beer (not the kegerator temp or a glass of water in the fridge). In this case, at 38 degrees beer temp, you must keep about 13 PSI on the keg. By running 4 PSI, you're simply changing the flow rate of the beer and nothing else. When you crank it back to 13, you THINK it's causing more foam because foam looks like it's flying out of the faucet and you need to give everything time to equalize.

There is some science involved in dispensing draft beer and trying to make up your own rules won't work.

Trust us, put the pressure back to 13 and LET IT SIT for at least 24 hours. Then pour a beer and tell us what you get. And, keep in mind, even if you get a little bit of foam for the first second or two of the pour, that doesn't mean anything is wrong. But, don't try to pour beer on top of foam because all you'll get is more foam. Have a spare glass sitting there, pour a little into that glass and then finish pouring the rest of the beer into a clean glass.
