Hi guys,
sorry for the long delay between responses. I have so many projects going on at once that I had to put this off for awhile.
So, you were correct about the pressure. I didn't have everything sealed and that was the first problem. After I got everything setup correctly the pump did indeed work, but the pressure was far too great (even with a ball valve) so I returned the pump and bought the same exact one you recommended.
Now i'm having another issue unfortunately. The mist king valves do mist but only when I have the ball valve turned off completely, and then after about 20 seconds the tubing bursts out of the pump spraying water all over my living room. The pump also makes weird noises and ticks now. I'm not entirely sure what the problem is.
I'll try to post a video shortly so you can get a better idea of whats going on.
