Me too, but it was just a trickle, also possibly acting as a syphon.
Anyways the solution to cleaning trub out of the spunding valve:I took a 2" peice of the silicone wort transfer hose, pushed it over the top of the valve, then looked for the 4 holes in the valve, and cut one hole in the hose that lined up with one of them. Hooked up an empty (rinsed and dried) keg to my fridge, and shoved the other end of the hose over the draft tap, turned it on. Repeated 8 timers, meaning two rotations, so that each of the four holes was the only air escape at two times, gave each time a couple second C02 Blast.
fixed.
The seperate pressure guage on the other hand... I'll be getting a new one of those.
