thanks for the reassurance. When I read about this, it sounded good but I was hesitant to start cutting pvc. I’m newer to a sump tank so I’ve been lost. It’s nice to hear you both recommending to do this so I definitely feel more confident now.
No problem. Like said above. It's the siphon you want to eliminate. Right now you are causing an intermittent siphon causing the water level to rise and fall randomly. By raising the water to hit the emergency drain then you will break the siphon and equal it out. You just want to lower the emergency drain so your water level isn't so high.
