Anyone using a DIY pipe overflow?

As I don't have any airline intake on my return pump, I was planning to connect my airline tubing to my intake pipe by percing a little hole and gluing the other end to it like in this design but instead it would be connected to the intake tubing: Do you thik it will do the same? The coming water from the return pump should create enough pressure to suck back any air that could get trapped in the overflow pipe, and with the check valve, it prevent the intake water from flowing back into the overflow. Do you think that will work? I got this idea from the MAME overflow which is working that way.

Just make up one of these, and stick it anywhere on the intake side (low pressure) of your pump. It does not need to be glued if under water right at the pump intake. But higher up, on an an intake line, needs to be glued properly. You could even just stick the airline tube into the intake (being careful that it doesn't get sucked into the impeller, and it will work. Many ways to do it...

But don't use an aqualifter or any air pump, becasue if it fails, you are hooped....
