i have a pin lock keg with a leaking static relief valve. The lid looks like this: enter image description here

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.

A socket wrench with the "smaller" adapter fits almost perfectly.


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.

  • The OP's picture shows a PRV on a pin-lock corney keg, which has no pull ring, but you are talking about the PRV on a ball-lock corney keg, which does have a pull-ring. Jun 15, 2015 at 19:09

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.
