I noticed one of my autopots water line was never going down. Water was constantly leaking thru the valve and not allowing a proper dry cycle. Plant showed signs of overwatering. This is what I did to fixed the problem.
Unscrew the tube collar and hold the valve upside down in your palm and blow into the valve. If you can blow any air thru the valve then you need to reset both rubber pieces by taking it out and giving it a good squeeze. Repeat steps until you can longer blow thru the valve no matter how hard you try.
