Buzzing Manifold

[dmarr06]

Use a manifold in the new kegerator and when I pressurize the keg it starts to buzz as I open the valve to the keg. The buzz drops out the longer the valve is open. I can't find any threads about this so I thought I'd ask.

Tried soapy water around the connections with no luck. Thanks in advance!

Sure its not the regulator?

What you are hearing is the check valves in the ball valves. It is basically a small ball held in place by a spring. As gas moves through the valve as a high speed (when filling an empty keg) the ball opens and closes rapidly as pressure is equalizing through out the system.
