Filter Drops Output

Recommended Posts

G'day, I've just installed an Eheim 3 pro filter on a new set up. When the filter is first turned on it will run a near full output but after 24 hours it reduces its output to next to nothing. I have checked the mechanical filters and the Bio filter media and there it no obvious obstruction in either. The unit has stood around unused for some time ( couple of years) but apart from that it is all as new...

 

Can anyone float any ideas on this problem?

Cheers Jim

Forgot to say that when I turn it off, take out the baskets (nothing too see really) put it back together and turn on it all works fine...... for a while.

If the impeller is good, and motor still runs, the next prob is the small connector inside that leads to the output pipe. You need to make sure that all parts line up. Its hard to explain but its the middle piece when you take out the top cover.

Yesterday I stripped down the unit. There is not much too them is there.
Anyway, I couldn't notice anything broken or out of place, but the output pipe may have been dislodged and I just didn't notice. In my unit all the parts are dark grey so I kind of didn't know what I was undoing until I had undone it. ( that's the way I roll, shoot first, ask questions later..)
Long story short, I put it all back together, making sure that everything was locked together good and tight. I turned it on and yahoo, output was back up to just about full, and even better , I have just checked it this morning and it's STILL up near full after nearly 24 hours running!
Fingers crossed it was just the output pipe dislodged. 🤞
