Quick question:
How do you know what is the flow rate in parts of your loop?
By definition, flow rate within a continuous loop must be uniform unless you have different ID tubes within the same loop.
It sounds more like you think you have a block/restriction rather than a change of flow rate.
the tubing is the same the only difference I can tell the tubing connected to the pump is full and you can feel it moving, the part connected to the rad seams empty and you cant feel it.
the ones with the blue line are the ones, I cant tell if they have any water
Yes it helps, I can not find any leaks, Im getting good temps, I hope theres no leaks.
I just wanted to know if it was normal.
Perhaps next time when you re-do your loop, you can stick it a flow meter to see how the flow rate is in your loop.
