I have a dual siphon HOB overflow. I used to be able to get it to work. Know I seamed to have forgot. What do I have to do to get it to work? Meaning that I need it to siphon thw water down to my sump

If it is a u tube overflow, just put a air line inside the u tube until it is a little past the bend and suck on the air line untill it starts to flow. Make sure both ends of the u tube are under water or it will not start.
