So after a while of being a PC enthusiast, I finally decided to tying hardline tubing for a watercooling system I build. Everything went well up until the point I put my fluid in my res. I am using a D5 pump and when I power on the system the pump is clearly running (it hums and creates ripples in the coolant) but the pump doesn't want to move the coolant to any other components in the system. I don't know what the problem is and thanks to anyone in advance for helping.
