So last night I scraped my old PVC siphon for a DIY PVC overflow.
Built it just like this: http://www.youtube.com/watch?v=7DFk4bnIxEg&feature=related
I set everything back up and now I can't get it to prime. I have the check valve in (the right way) I have filled the tank/tube. I have tried to suck the air out to prime it. It will start to overflow...until I stop sucking then the water backs up into the tank and stops. Why can't I get this primed? Any help/idea's would be great. Thank you
