ok, i'm new to the whole water filter thing. and to be honest, i'm not even using it to filter water...i'm using it to filter beer. but with that being said, i gave it a shot the other day and it failed miserably. the filter i bought is supposed to fit the filter...the standard 10 by 2.5 inch. it was just a cheap 5 micron woven one. i noticed that when i put the filter in and closed up the housing, the filter could still move around when i tipped the housing around. is that supposed to happen? maybe it was seated in there improperly or just simply didn't fit and maybe i got a bad filter. seems to me that if the filter can move around just by tipping the canister when it's closed...there would be plenty of room for the water (beer) to bypass the filter cartridge. could anybody give me some insight?
