Cannot get my overflowbox to fill and hold the siphon

Hi there,

You might have something stuck in your over flow, whcih causes sediments to accumalate until they block the pipe, which causes the whole setup to stop. They can then drool down to your sump, so by the time you get in there to clean it up, it all gone.

Try giving the inside of your overflow a nice cleaning, if you can pull your pipe, clean it out too. If it is still causing problems, it is probably not the overflow, but rather a pump or something. Does the tank keep filling after the overflow dies??
