After using this filter about 8-10 times now I am not pleased with it at all. I am working with derrin now to figure out what my problem is but I am getting such small flow rates coming out of the filter. I have the filter before my pump but this weekend I am going to switch it up.
Is anyone else having problems with flow rates?
Yes, he has his filter plumbed backwards.
As for flow rates, mine varies to some extent and I can't exactly find a common correlation, pellet vs whole vs old, etc. I have plugged my filter on one occasion, but it was nearly full of sludge. There is no way to fault the filter if you cram more material in it than it can hold. I have considered coming up with some type of "pre-filter" to catch the bulk of the junk so that this one can filter only the finest stuff. However, it is far easier to just use a hop spider and not worry about it.
One has to consider that everything has its limitations to some degree. I think the best thing to do is find an approximation of the volume of hop sludge that is going to result from the amount of hops being used. And if that is greater than the volume between the filter screen and the outer wall of the tube, then a hop spider should be used. Regardless of how well it is designed and built, expecting to stuff 10 lbs of crap into a 5 lb bag just is not going to work.
I would also add, the flow seems to have a pretty strong bearing on how soon the flow will diminish and to what degree. Flowing too fast creates a lot of turbulence inside the filter. Instead of allowing the material to settle in the bottom and work its way up, it immediately coats the entire surface of the filter creating smaller pathways for the wort to flow through. This will lead to plugging much more quickly. This is of course my opinion, but seems to hold true with each use.
