Now be careful you don't kill them.
Visions of draining a clarifier tank flashed thru my head....
If you're referring to the time my drain on the clarfier tank consisted of a hose in the vertical position, when not draining the tank, and due to a defective zip tie fell to the floor and drained the system that can't happen again. My clarifier drain hose now has a valve on it in the closed position when I'm not draining it and it's no longer in the vertical position. Likewise the external standpipe has a gate valve aka knife valve on it although I will soon have a valve behind the gate (knife) valve as they are prone to a slow leak as you know.
As they say on Koiphen site: If you don't prepare for Murphy he will get you!
