    A tidbit of info on that system: The knob is supposed to rotate freely on the push rod. If it is corroded and stuck, pushing on it tends to unscrew the rod from the nut on the bottom, resulting in a leak. You might try just turning it back in. You might get lucky. But of course the real solution is to free up and lubricate the knob so it doesn’t turn the rod.
