Swapped the mid position vale and it will now not fill back up.

The odd thing is the header tank did not drain off - it was still full
when I went to turn the water on.


Suggestions?

If there is a pump, make sure that there is water in it by opening the
bleed screw and then apply power.

Also bleed radiators.




There may also be a bleed in the high point of the hot water system.
Mine had an auto bleed valve but the screw on cover was tightly on thus
only allowing a limited amount of air to escape until the cover was
unscrewed.
