I have these on my eheim classic 2215. Seems like every other time I take the filter out for cleaning when I go to put it back together it drips water at the center part where the female and male parts connect
Im getting really frustrated I ordered a new one and it worked fine for 3 water changes now this new one is leaking . Ive tried petroleum jelly on the rubber gasket , I also don't over tighten.
Is this a common problem any help or suggestions folks ?
