I have a tank where I constantly have to adjust as well. When I use the trickle into the Emergency drain method its not long before it starts to trickle faster, then I have to adjust again. I also have a gate valve and all that...tried adjusting the return flow as well. Tried drain line submerged and above also. Noise isn't an issue for me so I just opened it up and let it rip.
