Ok, I'm done brewing until I figure this out. I am using keggles for my kettles and have dip tubes to get the wort from the bottom so I dont loose much during pumping. Ive tried installing a filter screen from my local homebrew store but it quickly got clogged and i had to remove the dip tube so i lost a bit of wort from my boil kettle. midwest has filter screens that could attach to the ball valve but they arent curved so i would have the same problem of loosing a gallon or so off the bottom. I hate the hop bag solution because there is still the (likely) chance of misc particles going through the counterflow and into my fermenter, and the one time i used a hop bag it was a pain.
What do you guys recommend? Thanks!
