I have an EHEIM Pro II that is about 4-5 years old. Lately if the power goes out the back pressure from the tank seems to force water out of the filter where the motor mounts to the filter media box. Do I need a new gasket or is there something else wrong?

Cheers,
Jeff
 
check the seals you may need to replace one
 
The Eheim II Pro filters can have an issue with the primer button o-ring. Eheim does not sell this part. Go to this site www.atomicrice.com as they sell the o-ring and also have very good photos explaining how to disassemble the filter motor housing to make the repair. I have purchased from them and am very pleased with the results of my repair. My filter no longer leaks when the power shuts off.

Interesting. Where did your filter leak when power was disconnected? At the primer button or at the connection between the top motor assembly to the media cannister?
 
Where the cord comes out of the top motor assembly. What happens is the o-ring for the primer button allows water to pass by it and travel up to the cavity the motor housing sits in. Then that cavity fills with water and runs down the side of the canister.
 
I ordered that primer o-ring as well as the main o-ring for the top assembly.

I was wondering what you guys would recommend for added protection against future flooding should the o-ring fail again. I was thinking of the following:

1. UPS Battery backup for the filter
2. Drain pan below the filter (should it drain while on vacation)
3. Normally closed solenoid valve on the intake line to the filter, perhaps on the output too?

Any other precautions?

Cheers,
Jeff
 
I have mine sitting in a plastic kitty litter pan. I have unplugged it but left the shut off valve open and it still hasn't leaked. I'm satisfied with the repair but it shall remain in the pan for the rest of its life.
