Are there gate valves that are more precise than the schedule 80 ones found on BRS? It’s just weird that the smallest adjustment makes the water level in the overflow go up and down so muchI had to put a strainer on my old tank to keep it from tornadoing inside the overflow box. I did this act for 2 years. Best I got was super tall emergency drain, short main drain with strainer and set it as best as I could with the gate valve. Hope you have better luck then I
