I learned the hardway....leaked out a 15lb tank pretty quick. I have 4 cornys and 2 sankeys in my keezer atm. Discovered 4 leaks. None of them you could hear either. Easy way to check, get a spray bottle and fill it with dawn dish soap and water. Spray all you connections. That will make it pretty obvious if you're good to go or not
