Help with overflowing sump system

[Myka]

Twist the black loc-line pipe so the output is closer to the surface and/or drill a 1/8" hole in the plumbing somewhere to cause a siphon break (though I don't really see a spot that would help you out). If the black pipe is too short, add more to it. The output should be as close to the surface as possible without causing splashes or a vortex. This will minimize the back siphoning.

lift the return line u closer to the surface to suck in air and break the syphon on a power outage

edit: you hit reply, you go pull out dinner and you get beaten to the answer

You could also put a flap checkvalve right on the output of the pump. The weight of the water in the return line will shut the valve when the water stops preventing the back siphon. I know alot of people don't use them but I put them in all my systems and have yet to have one fail. Combine that with a siphon break hole up top and you should be pretty safe all round.

Did a quick search and I think a flap checkvalve looks very efficient. Do you know where I could get one specific to my size of tubing? I will measure the diameter tomorrow. Also I dont have lots of supplies for plumbing so what needed pieces do I have to purchase before installing the valve? also where would I drill the hole and how big would it be?

Many thanks to the helpful replies

You have misunderstood what myka and I are saying.
The black plastic thats the output of the pump just aim a little bit higher say 1/2 inch under water so when power goes out and creates a siphon as soon as the black loc line #1 is out of the water it will break the siphon stopping flow.

My flap valve fails all the time the best solution is to lift the black return pipe as close to the surface as you can , you can also snap on some more links to make It longer , also you don't need it completely out of the water just right at the surface , when the pump stops running the water will drain a bit lower the level and breaking the siphon

Thanks everyone , I tried raising the black pipe to the point where it breaks the siphon but water is still slowly going down so It seems like it is leaking so I would need to get more black pipe pieces


Does anyone know where I can purchase more of them and also a more specific name other then black pipes?

Thanks

its called loc line and its cheep. I have a bunch you can have but the trek out to male ridge would probably cost more than buying it at JL.

Thanks to everyone who responded.
I took apart the valves and added teflon tape, and drilled a little hope underneath the PVC connector and it seems to have fixed the problems.

Also redid my aquascape a little bit and ill post an image once water a cleared up to get some opinions.

Thanks
