HELP! Leaking Eheim Professional II filter

[Keri]

So, when the filter is on: No problems. Turn it off.... slow leak from the top. Cover seal, all the way around the top seems to be the problem though when you take a look at it it seems ok?

It must build up too much pressure from the tank above when the filter is off.

Filter is plumbed in underneath the tank. The dripping is very slow but if we get caught in a power outage it could be very, very bad.

Does anyone know if you can order a replacement seal? Or does it just need to be lubed? Seal is still soft and relatively pliable.

I'd like to keep the filter, it works well other than that.


Any advice appreciated!

I think there's an eheimparts.com site? Also try ebay as you can sometimes find them cheaper there. I always give my gaskets a quick wipe and also apply a little silicone grease to them to keep them pliable longer. Sometimes the rings just get old and need to be replaced. It's a good filter. I've had a 2028 for years without problem.

Hi are you talikng about the seal ring between the powerhead and the canister, if so try lubing it do not use vaseline. Use a silicone base lube like Dow Corning 111 sealant
and aquarium safe, you can probably get something similar at the LFS. Be sure both surfaces are cleaned well before you lube it, I've found that seems to work well. Good luck. Cheers Laurie

Thanks Tony
It says:
7343150 (OUT OF STOCK) Sealing gasket 1 $24.02

BUT - at least that's a start! I will check ebay too

I'm going to try to pick up some silicone grease tomorrow too

lol - my husband got crafty and slapped on an unused fluval 304 we had kicking around, that will do in a pinch but I'm still going to try to order another seal.

Try searching on Bigals Canada website. I think BCAquaria members get a discount. They do stock a lot of ehiem parts but of course the prices are a bit steep. I've ordered Ehiem parts from them a few times. Never had any problems.

First thing I do when my Pro II starts leaking (same scenario as yours) is to replace the seal - works everytime. That reminds me to order another seal as a backup. Let us know where you picked up yours from. When there was a Big Al's in town, they used to charge $35 for a new seal.

Contact Grant at Island pets just got some spring clips from him a few months back for a 2217.

I got mine off Ebay when mine leaked. It's a known issue with the Pro II's, along with hairline cracks of the quick release adapter over time. Hence the reason for a design change in the Pro III's.

Thank you, that is what I keep reading as well. Right now the tank is switched over to the fluval 304. I'm thinking of keeping it on there? Having the risk of frequent leaks doesn't appeal to me tho I suspect the eheim is generally a much better filter.
