I just got off the phone with Eheim. Impeller shafts and bushings are not part of the warranty coverage. If the motor failed or if there was a crack in the filter housing, that would be covered. Impeller shafts made out of ceramic break very easily when exposed to the following: high heat, plant matter, sand, gravel and of course the obligatory "filter materials not manufactured by Eheim." Don't ya love that one? It clears them on about 75% of all purchases, especially from the US.
The man I spoke with was for Eheim North America. He was very nice. He told me the only way I could ever get the warranty honored in the US is if the unit is directly out of the box and never had water run through it. How would you know if it worked? I know this is typical throughout the US. A lot of products with a cord and plug or computers have this kind of warranty. The digital camera I just bought had a huge sticker on it: once you open this box, you cannot return it. If you purchase an extended warranty for extra money, then they'll take it back. Total scam.
So, I asked Mr. Eheim if there was a large tubing adaptor for the Eheim pre-filter. Of course not. He told me exactly how to make one, though!!!!

This lowers the risk of the impeller breaking and add bio-filtration. You take a core sponge and take a cylindrical chunk out of it. Make sure it's snug around the intake. This will prevent any material from getting into the filter.
I would imagine the EU would have stricter rules for warranty enforcement. The US can get away with murder, literally, on things like this. So out of touch with the rest of the world.

You should see our car warranties.
