Does anyone have experience adjusting the radiant floor distribution valves? Some of my distribution lines seem to be cold while others are warm to the touch. I've tried opening the valves on the lines that are cold but it doesn't seem to make any difference how much I turn them.
In order to adjust the valves do I need to only turn them a slight amount or do they need to be turned alot?
Which way do they need to be turned to open the valve? to the Right or Left?
Thanks for any advise you have.
