Beer spilling from liquid post

[ajmuzza]

Got a new pin lock keg which I filling and carbed over night. I've depressurised from carbing pressure and attached Pluto gun but after using the gun beer seems to be coming out of the top of the liquid post despite the Pluto still being attached. Presumably this is due to a pressure differential.

Any ideas on how to fix?

If you detach the Pluto gun, does it still dribble out? if yes, it's likely the rubber oring at the top of the liquid out tube needs replacing (assuming the post is tight). If no, check the oring on the post itself

Thanks. Yep is starts dribbling out with the Pluto on. It's a small tickle. Will check the o ring.

Bit of lube on the oring could be worth a try too. Although it possibly has a nick etc or is otherwise rooted.
