Sounds like psi/gravity issuse. Is you keg lower than your fermenter? If not, you’ll need too. If so, you can increase the verticals drop which will lower the pressure needed to transfer and increase the rate of flow .I've done this mod (though with the plastic posts because the metal version of the pressure kit was backordered everywhere), and so far I love it's impact on my beer. Soooo much less degrading of my beer over time. But lately, I've been having issues getting the last six inches or so of beer to transfer. Once it gets to that point, it will just stop (or go so slowly, I can't see any movement). I'm pretty sure at this point that it's not a clogging problem because I've tried everything I can think of to address that. I've switched to a filtered diptube, I've cold crashed for a week before transferring, I've filtered my wort before it goes into the fermenter to reduce trub and hop debris, I've blown CO2 into the diptube to clear out any possible obstructions during transfer. But still the same issue, and usually at the same level of beer (with about a gallon left).
It's getting really frustrating because I brew 2.5 gallon batches, and I'm not cool with losing nearly 1 gallon each time. I've started putting the excess into soda bottles with a carb cap, or into my 1.5 gallon keg when it's available (not often, it's usually full of kombucha). But I have to do that with an open transfer using a siphon, and those beers usually end up with oxidation. Plus it's just annoying to have to do two different transfer methods and have beer in all these different containers.
Has anyone else had this problem? Could it be that the amount of pressure required to move the beer once it gets that low is more than my fermenter can handle? Would I get better results if I switched to metal posts that had o-rings on the underside, instead of using the plastic posts that don't have any seal?
I'm thinking about drilling a spigot into my fermonster and transferring through that with some tubing hooked up to my beer post. That will at least let gravity do more of the work, in case the pressure is the problem. Any downsides to doing it that way? It's not as contained, but I can't think of another solution. Any advice y'all have would be great!
What psi are you transferring at? You should also check for potential leaks in the system that are preventing full pressure.
Also, I will tilt the fermenter forward towards the dip tube
