I recently built a kegerator out of a vintage freezer. I've added one tap handle to the door with two more coming soon. The freezer has a latching handle and pretty strong closing action, which pops the tap open dumping beer on the floor...
Can I add a spring to the internals of my cheap faucet to make it close automatically? Does anyone know which one is a good size and strength?
An overview of the parts and assembled version of my taps:
This is the fitting, which I imagine is more or less universal to most shanks:
I'm going to hunt for a food safe compression spring that will fit in between the shank and the inside portion of the fitting that attaches to it. Hopefully it will provide enough tension to close the tap cleanly, or at least keep them from pouring out when the door slams.
It seems like most self closing taps listed online have a screw where the little "button" is on the front of the tap so possibly the plug(?) could be machined or replaced to allow for an external spring (avoiding the need for food safety).
