I've been using a "hopstopper" hop filter on my boil kettle for quite some time now and I'm not really happy with it because its so hard to prime my pump after the boil. The wort just doesn't want to freely flow. I don't know if its because I don't have the right fit at the bottom of the kettle or something else, but its a real pain to use. Its this one herehttp://www.theelectricbrewery.com/hop-stopper
Has anyone else had problems with this type of filtration? Another reason I don't like it is because its so hard to clean well.
What do others use to get their wort filtered from the hops after a boil? I brew in a 15 gal keg.
