Balanced my kegerator to nice results (5 ft beer line, copper tube covering line in tower, 45 degrees at second pour and 12 psi). Seemed all good. Recently I split my co2 line with a plastic T split to get a second keg carbing, planning on getting a dual tap at some point. Now I'm getting a lot of foam for the first 12oz or so. 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.
