Can't figure why. The regulator is reading 12psi at the same setting as before the split even though it is going to two kegs. Not clear on why. Thought I might have need to crank it up to maintain the pressure. The pour seems the same speed as before, fast but not unreasonable. Any insights would be appreciated. Trying to avoid buying a second regulator.
Agree with others, the "T" doesnt have anything to do with it. Either the the balance changed (temp) or you are sucking air somewhere. Sankey or ball/pin lock? If Sankey I have had it where everything works fine, disconnect the coupler and recouple and have foam. Sucking air was my problem.
The temp will change also as the volume in the kegs drop. Not sure why, but they will. So whatever VV you were are originally, you have to adjust as the PSI as the temp changes to match that original VV.
