Very UNHAPPY with Ehiem (product and service)

Forget email, pick up the phone and call: 888-343-4662

+1. I've bought 6 Eheim filters and one of them had a leak. I called and the tech was super helpful. I wouldn't use any other brands.
 
Bonne46, yes, that is the Vaseline you can use.

Unplug the filter, remove the tap adaptor by pressing the red safety catch to the right while pulling the adapter lever forward. This allows you to remove the tap adaptor from the filter head.

When you remove the double tap from your filter, the o-rings are on the end of the fittings that insert into the canister head. You can use a pair of tweezers or a blunt tip pick or even a toothpick to get the old o-ring out of the groove. Just lube up the new o-rings before inserting them into the grooves.
 
Ok well I just install the new o-rings and main seal with some lube on it. We shall see what happens later tonight.
 
Well woke up this morning, went and checked my filter out to see if the leak has been fixed and the outcome is nope. Lucky I have the filter sitting in a container so the water will not leak on my floor.

So the main seal gasket and the o-rings did not fix the problem. It has slowed it down its not pouring out like before but there's still a leak.

Anything??
 
Every O-ring seal has acting hard surfaces that the O-ring seals against. So that even if you buy new O-rings to seal the water getting by, the new seals are only as good as their smooth unmarred and unscratched hard sealing surfaces built into that canister and lid plastic that the O-ring mates up against.

So if the prior owner or yourself used a stake-knife, screwdriver, kitchen-fork, nail, or ballpoint pen to dig out the old O-ring or pry-open the canister lid and in the process gouge or crack the hard plastic sealing surfaces, the canister will be permanently leak damaged no matter how new the O-rings are or how much Vaseline you use. Unless your someone like me who knows how to fill a scratch or seal and smooth a gouge with filler and or repair a crack with epoxy and aluminum tape.

The damage is fixable, the key is if you have the learned skill sets to identifying the cause and repairing the damage. The fact that the new O-ring and Vaseline slowed the leak is an indication you are on the right track, however it may be that their is another cause for the leak you are not seeing like in the valve manifold or swivels which also have tiny O-rings and sealing joints. Water leaks seeming to come from one spot may be migrating from another, you may have to run the filter separate in a closed loop (bucket) with food coloring or florescent leak detector to trace the true cause and location of the leak.
