My wife recently got me all of the necessary equpiment for me to keg my first brew. I opened everything up, it all looks good. Got my CO2 tank yesterday. Hooked it all up to test it, and there are some leaks in the regulator.
I doubt the regulator I received was new. Is it common to get a leaky regulator? It seems to be leaking from the connections, and there is some white rubbery stuff that looks like someone had tried to seal it in the past.
Should I contact the seller (legit homebrew online shop) about this, or is this to be expected? If so, what can I do?
