Hello all. I have my 110.4 WaterBox running and cycling. Just a couple things I can’t find help with. I see with the overflow the sweet spot is with the tank water level being just below the emergency drain in the overflow, is it is a simple as just draining water from my display as it is currently over the emergency drain? Also I have made adjustments with the gate valve and it is constantly making a noise like a bath drain when it starts to take in some air with the water draining so quickly, is that normal? Even with that I am getting some gurgling which I’m not sure is my emergency drain or main drain. Thanks.
