Eheim 2180 Issue

[akumastew]

Hi All

I got my tank set up and moved on to setting up the filtration.

I have an Eheim 2180 Pro III.

At first I couldn't get it to prime, so I took of the inlet arms, and used gravity and a little sucking, and got the filter to work.

I noticed that the filter worked fine like that.

I re-attached the assembled arm, and the filter lost its prime.

If I completely submerge the arm, the filter runs fine.

So I know that it was sucking in air from there.

Has anyone else had a similar problem? If so, what did you do to fix it.

I tried taking both inlets apart, and re-assembling them. But still had the same issue.

Picture Added:

The problem is where the black L shaped connector attaches to the in tank tube.
