Hi Guys,

New to watercooling here so i'm curious if someone might be able to lend some insight. I'm building a Monsoon Reservoir that has couplers (2 ports on each one) that can connect individual segments of 50mm tube. I thought I could use the 2 ports as one as an outlet, and one was an inlet for my CPU block, but someone told me they are both inlets. Does anyone know? I've enclosed a photo and would appreciate any insight?

Appreciate it,

They are all inlets, the only outlet would be from the pump. In order for any of the upper ports to be an outlet there would need to be pressure at the port that would mean the tube would have to be split one side pressurized an one for return. I don't see that in your pic.
