I just started kegging. I have a beer in a 5 gal ball lock keg. I connected the regulator, set pressure to 15 psi and connected the gas line to the keg.
When I connected the liquid line (standard picnic attachment: http://www.austinhomebrew.com/product_info.php?products_id=1271) beer immediately began spewing from the faucet. After disassembling and reassembling the faucet, this didn't happen again.
I also noticed that some beer flowed into the gas line. How did this happen? Did I overfill the keg?
Will this damage the regulator?
