I'm back from the dead. lol Now down to business. Yesterday I notice that my eheim 2215 was just barely had water trickling out of it. Being my birthday and having company I just unplugged it until today. So after taking it a part and cleaning everything, I now hear a loud knocking sound coming from it. Now it won't pump any water and it just knocks pretty bad. So can anyone tell me what's going on with it?

I'm going to guess it's impeller related. Is it air locked?

When I clean out my marineland canister, it often takes a little bit to start pumping water and stop making a racket. Make sure you've got the filter full of water and it's primed.

I did and I know that they can get air locked, which is why I took off the top a couple of times to see if that was it, but I had no luck.

All valves are open, no blockages in the tubes? No pockets of air in the intake line? These are obvious ideas but sometimes it's the little things we miss.

So I was able to look at it fora few seconds ( I have a 15 month old) and one of the tube on the intake side of the filter was clogged. Freaking MTS! That got some bubbles pumping out and then it stopped again. I will be able to look at it some more tonight after the kids go to sleep.

A knocking noise is not a sound I have ever heard from an Eheim filter.

If you also cleaned out the impeller well area, make sure you did not lose either of the two black rubber bushings that support the impeller shaft as that could be the cause of the sound you are hearing.

 

[Sharkfood]

Knocking sound generally means that the impeller shaft is not seated, or the bushing is excessively worn.

How do I fix that?

Hammer

 

[will5]

What?

 

[DogFish]

Sorry...couldn't resist.

How do I fix that?

If you're lucky, take the impeller out, clean it and its housing thoroughly, and put it back together carefully. If you're not, there may be a replacement bearing available somewhere.

 

[will5]

it's fixed! I took everything apart and cleaned it with a tooth brush.

 

[deeda]

Excellent!! Did you find anything unusual?

 

[will5]

Yeah...MTS clog's throughout the filter. :angryfire

How close to the substrate is your filter intake? Wouldn't the filter medium prevent the filter from clogging (the medium would clog but the entire filter shouldn't).

Anyways, try putting your intake a bit higher.

MTS are wily little guys and have learned to crawl down the intake pipe and creep into the intake strainer so they really don't care how close to the substrate the intake is.

My intake is not close to the substrate at all. But they appear to be getting in because I have the intake up against a piece of driftwood. They were not the only problem though. They clogged the tubing where I had put some connectors and some of the filter floss got wrapped around the impeller shaft. And I guess it just needed to be cleaned over all.

 

[JRMott]

lol, I was thinking of the wrong acronym!

MTS = Malaysian Trumpet Snails -but also-
MTS = Mineralized Top Soil

I thought you were talking about soil getting into your filter...
