Osmolator Pump getting a little noisy

[alienz]

Seems to be quite a bit louder than it used to be anything I should do? Doesn't look like it's really meant to be taken apart.

Any ideas let me know thanks.

They sometimes get noisy, it could be air inside, you could try tipping it up while it is running. Often the noise goes away as suddenly as it came on, sometimes it means the pump is starting to fail.
