I have 6 taps all set up with 1/4 inch lines....I am running about 12 feet on each keg and everything seems fine to me. I keep reading how I need to go to the 3/16th lines... however all of my fittings are 1/4 inch...will I have to switch out everything or just the lines? I think it is about time to install new tubing so thats why I am asking.
