pvc overflow problem

[Dav3]

With it in tank pull the end cap off and fill that tube up with water till it reaches the T off. Then start sucking on the airline. Might take a while but it should start. You have to suck out most of the air in the PVC between the inlet and the T.

Dry fitting the PVC may not work though.

Got it up and working after i recalled i needed to supeglue around the check valve to get a good seal.
It has keept siphon after a few pump stops but will keep testing.

Looks good. You may want to suck on the airline once a week or month till you get no air coming out. If your return pump matches the overflow you shouldn't get any air buildup but good to check.

Getting ready to make one of these myself. The hole in the end cap is not negotiable then?

It is required.
