Drill a hole just below the running water line as a siphon break. Angle it down towards the water so there is no spray or noise. It'll take care of yaHello. I'm taking over the service of my tank. I'm not happy with the water discharge line. It was installed several inches below the water line. If the pump stops, all that water back siphons. I searched and couldn't find an outlet nozzle with anti-siphon that fits the discharge line (1-1/2"). Any suggestions?
If the return ends several inches below the water level drilled holes will do nothing but make it worse.
You need to extend the return up to near the water surface. This makes it so only a very small, easily measured, amount of water will back siphon to the sump in a power outage or if you shut the pump off. No drilled holes to have to clean and maintain, and still fail, and no check valves to fail. Keep it simple.

I went with this back flow valve. No springs, no flapper, just a gravity driven stopper and work like a charm. I have just above the return pump. I over plumbed my systems sump so that there are no overflows of the sump issue that will happen.
I even put a emergency drain at the top of the sump so that the water will flow directly outside even if the overflow kept draining.

Thanks to all for your input. I went with AZDesertRat's suggestion. Although I think the back flow valve would have also worked, I use them in my line of business and they do fail at times. Thanks again!
