Just purchased a kegerator! Very excited. Gonna use a 5 gal ball lock keg. Couple questions. 1. How much line should I use from keg to tower? It was equipped for commercial and bought a kit to swap back and forth from commercial to home brew. 2. Does kegging really save time conditioning compared to bottling? 3. What's sop when not drinking out of keg? Shut c02 off or do I keep co2 on it all the time. Sorry for all the questions but starting a whole new path of home brewing. Thanks in advance
