Eheim 2126 Noisy After Serice

[andymiller6891]

I have just disassembled the top cover of my 2126 pump head in order to apply some silicone grease to the red o ring around the priming handle, sinse re-assembling i have found the pumnp to be noisy while running and there is a constant stream of tiny bubbles coming up the out flow tubing???

anyone have any idea if this will pass or is there a leak somewhere, there are no visible signs of water coming from the filer around the canister top or out of the priming handle, it just seems like i have disturbed something??

any ideas??

it should pass eventually, give it a shake and see if more comes out.

its been running for about 20mins and still seems to be passing loads of bubbles up the outflow, but none are coming down the in flow, seems like air is getting in somewhere in the head.

Sorted it, Used This Guide and realised by pushing the pump head back in through the bottom it was dislodging the oring from its seat and causing a place for air to get it, followed the guide to the letter and now all is well.

Thanks.
