Rattle! Filter problems...

Recommended Posts

So, my recently acquired used eheim classic 2213 canister filter has developed something of a... rattle.

This much vaunted workhorse isn't invincible after all. :no: I'm pretty sure this is down to the impeller. I have cleaned it, greased it lightly with vaseline and just taken it out hopefully and put it back again, but to no avail. The rattle persists.

Is it time for a new impeller? I did notice slight wear on the white plastic bearing at the base, but this is so slight I'm not sure it's the cause. Any comments and advice greatly appreciated- I want that famous eheim near-silence!

Thanks,

Andrew.

I've never had a canister, but I hear that if air gets into it, it makes a lot of noise. Maybe that could be it? :)

I've heard that sometimes you'll have to tilt the canister around to try and get rid of any excess air that might me trapped, as apparently these can contribute to noise; especially on the newer filters!

Hope this helps

did it start randomly while it was running or after you did a cleaning and hooked it back up?

Air in the lines is certainly one possibility, I would definitely check that out. I can't imagine you need a new impeller already!

Thanks guys, I'm pretty sure its not air, this is a different type of noise. Oh, and this is a second hand filter, a couple of years old

I had the same thing happen with my 2217, which is a few years old. I hooked it up after cleaning one day and it made this awfully loud noise. Disconnected it, cleaned the impeller, put it back together--and the same again. Repeated --same again. Decided it was the impeller and ordered a new one that has still not arrived. For 2 or 3 days it continued to make the noise--and then suddenly, it stopped.. In my case, not so much a rattle as a really loud and extremely annoying hum. I usually get rattling noises when there is air in there. No idea what this was, but in the end, not the impeller--and it cured itself. If the impeller shaft is not broken, I'd let it run a few days and see if it doesn't sort itself out before getting a new impeller.

Dang. I got a new impeller. Then during fitting it I broke the ceramic axle rod! Luckily the store had spare rods but they were a 40 minute drive away! So I put an air stone in the cannister to hopefully minimise any impact on the bb. What a headache! The new impeller is fitted now and it sounds less rattley, more loud hum. Mine started the same way, after starting up after a water change. Annoying much?

Actually, I misspoke before--it is still humming (or maytbe, humming again), I realized this morning. But not as badly as at first. I'll see if the new impeller, whenever it gets here, helps me. And I am going to mess around with it this weekend. If I figure it out, I'll let you know. We are, I think, in the same boat!

Ok, I figured out the cause of the rattle in mine. It was the thin white shaft that goes down through the impeller--mine had broken off at the bottom. I had not noticed it when I pulled the impeller out in my previous investigations. This time, I noticed the broken bit at the bottom. Replaced the shaft and all is silent once more--happy day. :)
