Guys,
These damn wheels keep popping off the valves. If you just screw them back on they seem good and tight, so do that until we find a better solution. If you need to drain one of these vats and the wheel is missing, one's probably lying around nearby. If not, check the locker by the stairs.
And one other thing. I know that one of you dropped his pocket watch into the reservoir pit and got the bright idea to drain the vats in order to raise the oil level to get the watch back. Do it again and the cost of the wasted oil comes out of your pay.
