Just took my Eheim 2075 proffesional 3 external filter apart to give it a clean and found a small (10mm maybe) white plastic sleeve on top of the blue sponge in the top tray. Now i am guessing it has come out of one of the pipe connections on the removable valves connections as it fits inside them but which one...input or output ?.....Thanks
