Hi all,
Finished up a custom watercooling setup and started leak testing. However, the water in the loop has been making it to each point and then sat there for a while now, not completely filling the tubes. The reservoir is topped of, but the pump doesn't seem to be pulling any water from it, it seems to be just stuck in the tubes. The pump is on and there are no leaks anywhere. The loop is xspc bay reservoir to Swiftech pump to ek cpu block to Asus GTX 780 Poseidon to 360mm HL Black Ice Stealth GT V2 back to res. The pump is on the bottom and some of the tubing does "rollercoaster" a little but nothing I would think that the pump couldn't handle.

Thanks in advance for any help.

Sounds like you may have an air bubble trapped in the pump.
You can try starting and stopping it several times. This sometimes works .
Or while it is running tilt the case forward and back then side to side several times.
Nothing drastic like completely on its side but 15 to 20 degrees tilt in all directions.
Do not let it run for very long without water in the pump. the ceramic bearings/seals will overheat and crack.

You are the man! Starting and stopping it finally worked the water through!
