I've had my keezer for a year now. Currently using Bev Seal Ultra, about 15' of hose per tap. Also using John Guest fittings to make the connections to the shank and keg disconnect. Having foam issues with one tap so took it apart over the weekend and cleaned it up. Had a little gunk inside the tap and on the o-rings so soaked everything in hot Oxy. Re-assembled the faucet (Intertap Stainless FC). Also ran some BLC through the lines which I do after every keg kicks. Keezer temp is set at 35 with a 2 degree swing. Beer pours around 40 degrees. I also store my lines between the kegs instead of sitting on top. Not real sure if there is an advantage to this or not. Also run a computer fan 24/7. Probably need to add another as i do not find this fan circulates enough air. Also, I have my regulator set at 13-14 PSI using 40 degrees as the point on the chart. For the entire first year, never had a foaming issue. Now, when i pour from this one tap, nothing but foam. I can also see some bubbles in the line but not sure if it's CO2 coming out of solution or air. Not sure how air could get in as i have no liquid leaks. There is also a gurgling sound and a little spitting when i open the tap which to me would indicate air or something in the line. I have cleaned the disconnects and swapped out to another one but still didn't help.. I also swapped out the dip tube but that didn't help either. Just trying to determine the root cause. I just cant seem to figure it out. I am about to replace the hose with new Bev Seal ultra that i have on hand to see if that helps but I don't see any restrictions inside of the hose i am currently using. -What would cause CO2 to come out of suspension and why would it just now start happening? -Is it best to store the hose in between the kegs or lay on top? I figured in between the kegs would keep the lines colder. -For those who have used the regular 3/16" beer hose and the Bev Seal Ultra, which do you prefer and why? I would consider switching out the hose but would have to buy tail pieces, which isn't a big deal. Anyone have suggestions on what the culprit could be?
