i have a pin lock keg with a leaking static relief valve. The lid looks like this:
I can't figure out how to remove the innards of the relief valve to fix it. Any ideas?
Just put a tool that fits this square hole and unscrew it counter clockwise (normal thread). A large enough flat screwdriver can be used between 2 corners, to. Inadequate tools could damage the plastic and make things more difficult. Find a good tool before you try.
According to Is this pressure release valve missing a pull ring? it looks like you might unscrew it from the bottom. Not enough reputation to post comments.
You could also just get a new lid. Several kegging supply sites sell new lids at reasonable prices and you could cut the pressure relief off that one, insert a grommet and now you have a fermentor.
