Answer to question 1 (Why doesn't my suction cup suck very well?):

You may have the secondary regulator turned down to low, or if you used a flow control valve, it may not be in the fully open position. Set the secondary reg. to 32 psi for maximum effectives. Also, try using more than one suction cup (we did) and it might work better. Also check for leaks.

Answer to question 2 (How to stop the suction?):

Turn the spike off, just like you would with any other solenoid or motor (or the compressor for that matter), the suction should stop within several seconds.
