I should probably know this, but I'll ask to be positive....are GRC (or all PB) radiators plumed to only flow on one side or are there cross vents to flow through both sides of the radiator?
If feels as if only one side is flowing. Most radiators flow in the top of one side and exit the bottom of the other.....or am I mistaken. Let me know.
