Im trying to see if there is a easy solution to this problem that I have not thought of. Im trying to prevent my tank from siphoning back into the sump should the power go out. I know I could raise the level of the outlet above the water line but that is noisier than I would like. My temporary sump is tall enough that it can absorb the water that will siphon back until the output nozzle is above water but once my more permanent sump is in place I do not know if that will be the case. I am looking at using a check valve but that is an additional layer of complication and I have heard they fail often. Any ideas or suggestions are appreciated.
DIY alternatives to check valve?

There is an internal corner overflow box. tank is drilled at the bottom and drains to sump. pump then returns water to tank via hose and nozzle. If pump turns off water siphons back from output nozzle. My camera broke so I dont have pics at this point.
You can raise the return pipe in the tank so it will catch air and lose siphon right away if the power goes out and also drill a small hole in the bottom of the return pipe to do the same thing. A check valve is not a big deal to install and IMO should be used, go with a quality valve like "Wye" a little expensive but a nice peace of mind.
Yeah, I raised the return pipe so that its just barely submerged. Any higher and I get more noise. I will probably get a check valve too but as a back up. Just wonderring if there are any other options as well.

Is this a mass produced tank/overflow or DIY? You can drill a small hole in the elbow of the return pipe just before it enters the tank. here is a pic
saw this on youtube, maybe it can help

btw, can some one help me with embedding vids?

Drilling a hole is the easiest (and cheapest) way to break a siphon. Check valve is unnecessary and will impact your return gph.
For redundancy, you can drill 2 holes.

When embedding a video, hit the "YouTube" button when in the advanced mode of posting and paste ONLY the letter coding in between the coding boxes.
So you will see this when you hit the you tube botton. You will get YT wrapped in "[]".
Like this [here] video code here [/here] but replace the "here" in between the brackets with "YT"
Then from the link that you posted above take everything AFTER the "=" Sign.
So you will see this FWK0BKKMnok between YT wrapped in brackets with no spaces....
When done correctly you will see this...
