Did you try to lube the gasket?
Did the leak occur after servicing?

At least with Hagen aqua clear they said to talk to the place I bought it, you may want to try that. Places like DrF&S are often very good with problems, replacement parts etc.

The leak did start after I cleaned the filter media. You think I should try lube first? What lube do you use?

Yup, plumbers grease found at any local home depot, lowes.
NO NO NO NO........

Only use pure petroleum jelly (IE vaseline).


I am laying good odds on the fact it is the priming seal, and this is a real weakness in this model.

Absolutely wrong. Vaseline will deteriorate rubber O rings. It is a known fact. Use the plumbers silicone lubricate.

A) use silicone grease. If that doesn't work, your seal is likely shot, and will need to be replaced. FWIW, Eheim provides a seal lubricant packet with all of their filters.

B) It sounds like the issue was caused by improper reassembly of the filter after maintenance; I would not jump to bashing the company on their service and warranty if the issue was not true equipment failure.

As to what additives are in plumbers grease I can't be sure 100% pure silicone would be fine as well, as long as it is not an aersol.

Possibly if the leak is indeed the main seal and not the primer seal. Just as likely is the filter was maintenanced, placed back into service, and when hooked back up the primer was pumped a few times without being lubed, and it was dry to boot.
