greatmoojin Posted September 5, 2010 Report Share Posted September 5, 2010 Hiya, we moved house yesterday morning and set up the canister filter in the afternoon. It;s an Eheim pro 2 and all functioning fine, but it occasionally starts whistling! Anybody had this before? What's the possible cause? I thought maybe air trapped in the unit so i did the old tilt and rock it back and forth trick, some air did come out, but it hasn't sorted out the whistling. I switched it off, waited a minute then switched it back on, restarted just fine, but still whistling. Checked the canister and pipes and no water leaking so probably not a small crack or leak either. When we woke up this morning it's still doing the occasional whistle, roughly as often and persistent as it was yesterday. Any suggestions?

Scottie841 Posted September 5, 2010 Report Share Posted September 5, 2010 Have you pulled it apart and checked the impeller shaft? The easiest way to fix it would be to go and buy a decent brand of filter Quote Link to comment Share on other sites More sharing options...

phoenix44 Posted September 5, 2010 Report Share Posted September 5, 2010 I have never heard of a filter whistling. how old is it? Quote Link to comment Share on other sites More sharing options...
Caryl Posted September 5, 2010 Report Share Posted September 5, 2010 Whistling? Perhaps it is happy To me it suggests air escaping somewhere. Have you checked the O rings and seals are all correctly positioned? I would have thought it would be water escaping though, not air :-?

smidey Posted September 5, 2010 Report Share Posted September 5, 2010 i would think it would be air being sucked in, perhaps at the hose connections. Quote Link to comment Share on other sites More sharing options...
suphew Posted September 5, 2010 Report Share Posted September 5, 2010 Canister filters are mostly under vacuum not pressure so it if it was a seal it would be sucking in air not leaking water. But for it to be sucking enough to make it whistle you would have tonnes of air bubbles coming out. I'd be looking at the motor and checking that everything is lined up correctly and not rubbing Quote Link to comment Share on other sites More sharing options...
Joe Posted September 6, 2010 Report Share Posted September 6, 2010 The easiest way to fix it would be to go and buy a decent brand of filter I thought Eheims were really good quality. So if they're not really that good then, what is the best filter you could possibly get? Quote Link to comment Share on other sites More sharing options...

Joe Posted September 6, 2010 Report Share Posted September 6, 2010 Oh. Sometime's it's hard to tell if someone is being sarcastic when they write something, because you aren't there to listen to the expression of their voice. Quote Link to comment Share on other sites More sharing options...
