Depressurising sealed system.

What assumptions are you making about my, or anyone elses, education?

In my experience, despite having provided ample space for the inhibitor by draining a quantity of water from the system, it will not flow from the Tee pipe into the radiator that I use as the insertion point for inhibitor. Rather it flows out. It doesn't matter if I use the Tee at the other end of said rad so it's not the angle of the rad that is causing problems.

Having enough space in the radiator to accept the inhibitor is only part of the solution . As I said previously air must be able to get out as the inhibitor goes in .( I cannot believe we are still discussing this 48 hours on after all the answers already given) so if the tube is not allowing air to leave then the inhibitor will not go in . Try using a smaller bore pipe or, as someone else suggested ,remove the plug that the bleed screw sits in and that should allow both the inhibitor to go IN and the air to come OUT .
