I thought I would share a couple of pics from my build, I have been using picnic taps for the last year and finally put in a tower.
I want to thank the OP for the copper tube idea, installed today and seems to work great. Seems to be conducting the cold very well....
I put insulation around each tube, one for each faucet and this made it difficult to get both into the tower. But they are not going anywere now.
Cheers and thanks all. I am cooling my latest batch now and I am sure that I will be back with line balancing questions.
