Hey thanks for the quick reply.
I replaced my monovalve about 6 months ago. I just pulled it out and checked it again though. All the rubber looks good on it. Should I maybe just try a new one? What you said makes perfect sense.
Well actually, I didn't test the electrical connection there yet. I'll make that my next course of action.
Thanks again.
