Coupler?

[CJ51974]

I just bought a kit, tower kit with the low profile coupler. I got everything hooked up followed directions but I get a good amount of foam in the beginning of each pour. After the pour I watch and all these bubbles form in the line from the coupler to the tap, the longer it sits the more an bigger the bubbles get. I feel like the coupler is the problem. When Its off the keg and the co2 is on, the co2 flows out of the coupler if it is not in the extended position, then when I twisted it open to full extension you hear it bubbling with the beer and leaking out a little still. Shouldent it not leak any co2 when its off the keg like that??

There is a ball ("Check Ball") in the center of the coupler that stops the beer from flowing out of the bottom of the coupler when not in the keg. If CO2 is leaking out when the coupler is out of the keg, the coupler is either not full dis-engaged or else the seals inside the stem of the coupler are not sealing.

Ensure there is a check ball in the coupler; you can check by shaking it and listening for a rattling sound (when unhooked of course). If you ever see bubbles creeping up the exit line from the coupler it is usually a sign of not enough applied pressure to the keg. Alot of foam in your pour can be a sign of this also. We’ll need to know more about your set up to figure that out.

thanks for the help, I think it is my coupler then, i bought this low profile one http://www.micromatic.com/draft-keg-...-FT44T-PR.html It does leak co2 and beer when the coupler is off the keg, when i twist the coupler it just changes how much it leaks but it still leaks. Im guessing thats my problem. They sent me an exploded view of the couplers insides heres a pic of that, sorry its sideways Yahoo! Photos - Picture But # 7 i the pic is the check valve inside of where the airline looks up, im guessing that is what is bad. Ill send it back and get a new one.

I replaced the coupler, it is still doing the same. It bubbles from inside the coupler and fills up the beer line with air, after about 5 mins the line has large spaces and large bubbles in it. I have to pour the beer for a few seconds before i can put the glass underneath to get the non foamy beer. My pressure is at 12, temp 38, everythig seems to be good no leaks at all, why is my beer line filling with air, any help would be greatly appreciated.
