So this tank has been up for over a year. Over the last 6 weeks or so I can't get the water level down in the overflow so it's not rushing into the emergency drain. This causes that annoying chugging sound in the sump. I've turned the adjustment knob both right and left 100 times. I don't know if it's not opening and closing the valve? The level doesn't move an inch in the over flow. I've even sped up and turned down the speed of my return pump. Anyone have suggestions?
