I cut out the bad valve (was afraid I would break things trying to pull the tubes off). Desoldered and resoldered the leads to the replacement. Somehow the valve that wouldn't close has started working!
I was also able to verify the 12volt PWM was actually working but the little pump wouldn't run while the signal is pulsing. I assume the pulse isn't long enough for the little DC motor to rotate to the next fixed magnet.
Investigating configuring the arduino timers to lengthen the pulse cycle, or alternativley programatically pulsing the motor to adjust the water output.
