Stopping drippers

Let me begin by saying this is never been a problem for me before, but recently I’ve had a new build. I’m trying to get the siphon to stop after pump turns off, it doesn’t, it’ll drip all 95 gallons if the system had its say. So I installed a 10’ riser bar at top of grade. Still nada. Today I’m gonna try pinholes right above the pump line, gonna put a drip like on it and reroute.

I’m surprised I didn’t find much, no NRV valves, I did find some solonoid valves but I don’t wanna wire that up to my pump , using 1/2 pvc. I though dig or another irrigation would have this easy problem fixed. Unless I’m not seeing it lol.

Thanks guys

Depending on flow you can buy an anti sython valve but I have one I tried but returns to much.
In the end I had a 90* in the tank with a tiny hole drilled in the end, that needs the be above the water line and will return a small spray back into the tank, but when the pump shuts off it takes in air and stops the sython

That’s what I did, along with a riser bar. It works great! Thanks
